0:00:00.080,0:00:01.199
today we're going to talk about the

0:00:01.199,0:00:03.199
urticating hairs of tarantulas so

0:00:03.199,0:00:06.160
let's get started

0:00:06.840,0:00:08.480
[Music]

0:00:08.480,0:00:10.240
welcome to the tarantula collective my

0:00:10.240,0:00:11.920
name's richard and if you're new to the

0:00:11.920,0:00:13.759
channel i make videos about tarantulas

0:00:13.759,0:00:15.679
scorpions and other inverts so if that's

0:00:15.679,0:00:16.800
something you're interested in

0:00:16.800,0:00:18.560
make sure you hit that subscribe button

0:00:18.560,0:00:20.240
now we all know that some species of

0:00:20.240,0:00:22.240
tarantulas have urticating hairs but

0:00:22.240,0:00:24.720
when it comes to exactly which species

0:00:24.720,0:00:26.720
have exactly what type of verticating

0:00:26.720,0:00:28.240
hairs it seems a lot of us

0:00:28.240,0:00:30.400
are confused on that topic so today

0:00:30.400,0:00:31.599
we're going to dive deep

0:00:31.599,0:00:33.600
into sete not literally though because

0:00:33.600,0:00:45.840
that would be very itchy

0:00:47.410,0:00:56.559
[Music]

0:00:56.559,0:00:58.480
there are two types of tarantulas in the

0:00:58.480,0:01:00.719
world divided up depending on what part

0:01:00.719,0:01:03.160
of the world you find them

0:01:03.160,0:01:04.239
[Music]

0:01:04.239,0:01:05.840
there are new world tarantulas that can

0:01:05.840,0:01:07.760
be found in north central and south

0:01:07.760,0:01:08.560
america

0:01:08.560,0:01:12.960
sometimes referred to as bird eaters

0:01:12.960,0:01:14.720
and there are old world tarantulas that

0:01:14.720,0:01:16.560
can be found in the rest of the world

0:01:16.560,0:01:19.200
usually referred to as baboons old world

0:01:19.200,0:01:21.439
tarantulas like those found in africa

0:01:21.439,0:01:23.759
and throughout asia for the most part

0:01:23.759,0:01:25.600
lack any urticating hairs

0:01:25.600,0:01:27.360
though they do seem to possess much

0:01:27.360,0:01:30.240
stronger venom

0:01:30.479,0:01:32.400
there can always be exceptions to these

0:01:32.400,0:01:34.400
rules especially as tarantulas have not

0:01:34.400,0:01:35.680
nearly been studied as

0:01:35.680,0:01:37.280
thoroughly scientifically as they

0:01:37.280,0:01:39.680
probably should be at this point

0:01:39.680,0:01:41.119
even the assumption that old world

0:01:41.119,0:01:43.119
tarantulas have stronger venom than new

0:01:43.119,0:01:44.159
world tarantulas

0:01:44.159,0:01:46.399
with the exception of a few species has

0:01:46.399,0:01:48.320
not been scientifically proven in all

0:01:48.320,0:01:49.260
cases

0:01:49.260,0:01:50.479
[Music]

0:01:50.479,0:01:52.799
that being said it is easy to observe

0:01:52.799,0:01:54.640
that old world tarantulas seem to be

0:01:54.640,0:01:55.439
more defensive

0:01:55.439,0:01:57.360
faster to flee and more apt to show a

0:01:57.360,0:01:59.520
threat pose in an attempt to intimidate

0:01:59.520,0:02:03.040
compared to new world species

0:02:03.780,0:02:06.640
[Music]

0:02:06.640,0:02:08.399
new world tarantulas are not as

0:02:08.399,0:02:10.720
defensive but they do possess urticating

0:02:10.720,0:02:12.480
sete that they will kick up in the air

0:02:12.480,0:02:15.040
when they feel threatened

0:02:15.040,0:02:16.480
around ninety percent of new world

0:02:16.480,0:02:18.480
species have these hairs though some

0:02:18.480,0:02:19.920
species like some opius

0:02:19.920,0:02:22.319
do not possess them urticating setae can

0:02:22.319,0:02:24.480
be found on the femura of the pedopalps

0:02:24.480,0:02:26.319
or more commonly on the abdomen

0:02:26.319,0:02:27.840
different types of tarantulas have

0:02:27.840,0:02:30.160
different sette or combinations of setae

0:02:30.160,0:02:32.270
located on different areas of the

0:02:32.270,0:02:34.840
[Music]

0:02:34.840,0:02:36.239
abdomen

0:02:36.239,0:02:38.160
it is said that species of tarantulas in

0:02:38.160,0:02:40.879
the gramostola lostyodora or acanthus

0:02:40.879,0:02:43.360
curia genera possess the most urticating

0:02:43.360,0:02:44.720
sete on their bodies

0:02:44.720,0:02:47.040
but to different levels of effectiveness

0:02:47.040,0:02:48.800
the er dedicating sete of gramostola

0:02:48.800,0:02:50.959
species are typically harmless to humans

0:02:50.959,0:02:52.800
and not very irritating at all

0:02:52.800,0:02:54.720
though tarantulas in the acanthoscuria

0:02:54.720,0:02:56.480
genus can have hairs that are much more

0:02:56.480,0:02:58.560
irritating and can cause severe itching

0:02:58.560,0:02:59.440
in rashes

0:02:59.440,0:03:01.360
while specimens within the genus of

0:03:01.360,0:03:03.280
theraposa are known to have the most

0:03:03.280,0:03:05.599
serious urticating sete that can cause

0:03:05.599,0:03:06.720
not only itching

0:03:06.720,0:03:09.599
and rash but burning sensations bumps or

0:03:09.599,0:03:11.519
blisters that can last for weeks

0:03:11.519,0:03:13.519
as well as the possibility of causing

0:03:13.519,0:03:14.640
breathing issues

0:03:14.640,0:03:19.519
especially if the hairs are inhaled

0:03:19.519,0:03:21.200
these hairs are not just kicked into the

0:03:21.200,0:03:22.560
air in self-defense

0:03:22.560,0:03:24.560
but they can also be used passively by

0:03:24.560,0:03:25.760
some species

0:03:25.760,0:03:27.360
and are transferred onto the webbing of

0:03:27.360,0:03:30.159
their burrows and surrounding areas

0:03:30.159,0:03:32.080
as well as onto their egg sacs in an

0:03:32.080,0:03:34.319
attempt to ward off predators

0:03:34.319,0:03:35.920
and counter to the common belief that

0:03:35.920,0:03:38.000
one can build up a tolerance or immunity

0:03:38.000,0:03:39.760
to hairs like can happen with medicine

0:03:39.760,0:03:40.640
or alcohol

0:03:40.640,0:03:42.400
the reaction to urticating hairs can

0:03:42.400,0:03:44.239
become worse the more you are exposed to

0:03:44.239,0:03:44.720
them

0:03:44.720,0:03:46.720
some hairs you found slightly irritating

0:03:46.720,0:03:48.560
in the beginning can become extremely

0:03:48.560,0:03:49.519
uncomfortable after

0:03:49.519,0:03:51.760
years of repeated contact leading some

0:03:51.760,0:03:53.680
people to no longer even be able to stay

0:03:53.680,0:03:55.200
in the same room as some of their

0:03:55.200,0:03:56.879
favorite species that they have kept for

0:03:56.879,0:03:57.439
decades

0:03:57.439,0:03:59.200
because the discomfort has become so

0:03:59.200,0:04:01.200
intolerable that is why it is important

0:04:01.200,0:04:03.040
and even imperative to be careful when

0:04:03.040,0:04:04.640
rehousing or interacting with your

0:04:04.640,0:04:06.640
tarantulas and take precautions like

0:04:06.640,0:04:07.519
wearing gloves

0:04:07.519,0:04:09.680
eye protection and even long sleeves

0:04:09.680,0:04:11.200
when there is a chance you can come in

0:04:11.200,0:04:12.560
contact with the cete

0:04:12.560,0:04:14.640
being macho and saying they do not

0:04:14.640,0:04:15.760
bother you now

0:04:15.760,0:04:17.600
may be true but after years of that

0:04:17.600,0:04:19.680
mindset you may realize your resistance

0:04:19.680,0:04:21.280
has turned into a sensitivity

0:04:21.280,0:04:22.560
that could make keeping some of your

0:04:22.560,0:04:24.479
favorite tarantulas very uncomfortable

0:04:24.479,0:04:28.960
or even impossible

0:04:28.960,0:04:30.880
while researching tarantulas it is

0:04:30.880,0:04:32.639
common to come across descriptions of

0:04:32.639,0:04:33.280
species

0:04:33.280,0:04:34.960
stating different types of urticating

0:04:34.960,0:04:36.800
hairs that use the numbers one through

0:04:36.800,0:04:37.440
six

0:04:37.440,0:04:39.199
though they usually go into no further

0:04:39.199,0:04:41.120
detail about what this means or what the

0:04:41.120,0:04:42.639
differences are between the different

0:04:42.639,0:04:43.280
types

0:04:43.280,0:04:45.120
in fact there are actually seven

0:04:45.120,0:04:47.040
different types and some species have

0:04:47.040,0:04:48.400
two different types of urticating

0:04:48.400,0:04:48.960
setting

0:04:48.960,0:04:50.400
so today we're going to break down the

0:04:50.400,0:04:52.080
different types of hairs and explain

0:04:52.080,0:04:57.840
what kind of tarantulas possess them

0:05:02.240,0:05:04.880
type 1 hair these hairs are about 0.2 to

0:05:04.880,0:05:06.960
0.6 millimeters and are embedded into

0:05:06.960,0:05:08.800
the skin by a penetrating tip

0:05:08.800,0:05:10.479
they are found on many species of

0:05:10.479,0:05:12.400
tarantula except for the gramostola

0:05:12.400,0:05:13.120
species

0:05:13.120,0:05:14.479
they are also the only type of

0:05:14.479,0:05:16.560
urticating hair possessed by the nondu

0:05:16.560,0:05:17.440
carponius

0:05:17.440,0:05:20.880
the p amazonicus and vitalius species

0:05:20.880,0:05:22.720
these hairs are not just effective when

0:05:22.720,0:05:24.639
kicked into the air but these tarantulas

0:05:24.639,0:05:26.479
will also kick them onto their webbing

0:05:26.479,0:05:27.840
and around their burrows

0:05:27.840,0:05:29.360
as they are effective and quickly

0:05:29.360,0:05:30.800
warding off creatures that come in

0:05:30.800,0:05:33.600
contact with them

0:05:36.000,0:05:37.919
type 2 hairs are a little larger

0:05:37.919,0:05:41.199
measuring between 0.5 to 1.5 millimeters

0:05:41.199,0:05:43.120
and are also embedded with a penetrating

0:05:43.120,0:05:45.440
tip this type of hair is exclusive to a

0:05:45.440,0:05:46.800
vicularia species

0:05:46.800,0:05:49.280
pasha to pelme species and era de pelma

0:05:49.280,0:05:50.080
species

0:05:50.080,0:05:51.680
they are not kicked into the air as a

0:05:51.680,0:05:53.680
cloud rather they are transferred by

0:05:53.680,0:05:55.120
direct contact

0:05:55.120,0:05:57.039
so when your evicularia is rubbing its

0:05:57.039,0:05:58.880
abdomen on you it may look cute

0:05:58.880,0:06:00.160
and you may think it's a sign of

0:06:00.160,0:06:01.919
affection but it's actually trying to

0:06:01.919,0:06:07.120
rub urticating hairs on

0:06:07.120,0:06:09.360
type 3 hairs are around the same size as

0:06:09.360,0:06:10.639
type 2 measuring

0:06:10.639,0:06:13.680
0.3 millimeters to 1.8 millimeters

0:06:13.680,0:06:15.680
and are also embedded by a penetrating

0:06:15.680,0:06:17.520
tip these are known as the most

0:06:17.520,0:06:19.360
effective and most irritating type of

0:06:19.360,0:06:21.120
urticating hairs to vertebrates and

0:06:21.120,0:06:22.560
invertebrates alike

0:06:22.560,0:06:24.880
they can be found on species in genera

0:06:24.880,0:06:27.120
like nandu

0:06:27.120,0:06:31.440
mega fapelma rockypelma

0:06:31.440,0:06:33.850
among many others

0:06:33.850,0:06:35.440
[Music]

0:06:35.440,0:06:37.680
type 4 these hairs are much finer than

0:06:37.680,0:06:39.520
the previous urticating sete

0:06:39.520,0:06:42.560
usually measured around 0.06 to 0.22

0:06:42.560,0:06:43.440
millimeters

0:06:43.440,0:06:45.440
and like most cete are embedded by a

0:06:45.440,0:06:46.560
penetrating tip

0:06:46.560,0:06:48.319
they are most commonly found on many

0:06:48.319,0:06:50.639
species like those in the gramostola and

0:06:50.639,0:06:52.160
youthless genus

0:06:52.160,0:06:53.759
they are very irritating to small

0:06:53.759,0:06:55.360
animals but are among the least

0:06:55.360,0:06:57.039
irritating to humans

0:06:57.039,0:06:58.880
so if you are sensitive to urticating

0:06:58.880,0:07:00.960
hairs gramostola and youthless

0:07:00.960,0:07:02.960
tarantulas are probably a very good

0:07:02.960,0:07:05.520
choice for you

0:07:06.479,0:07:08.880
type 5 these are extremely short and

0:07:08.880,0:07:10.400
light compared to other types of

0:07:10.400,0:07:11.759
urticating setting

0:07:11.759,0:07:13.919
and instead of penetrating the skin they

0:07:13.919,0:07:16.000
are embedded in hair follicles

0:07:16.000,0:07:18.000
also unlike the previous sette these

0:07:18.000,0:07:19.759
hairs are found on the femura of the

0:07:19.759,0:07:20.560
petaps

0:07:20.560,0:07:22.639
and are exclusive to the ephebopus

0:07:22.639,0:07:24.960
species

0:07:24.960,0:07:27.599
type 6 hairs are relatively rare and are

0:07:27.599,0:07:29.759
found in the himmerhaga species and are

0:07:29.759,0:07:33.010
also embedded in the hair follicle

0:07:33.010,0:07:33.500
[Applause]

0:07:33.500,0:07:35.199
[Music]

0:07:35.199,0:07:37.280
type 7 these are the most recently

0:07:37.280,0:07:38.880
discovered urticating hairs

0:07:38.880,0:07:41.560
described by galves and perez miles in

0:07:41.560,0:07:43.680
2016. they are exclusive to the

0:07:43.680,0:07:45.120
colombian tarantula

0:07:45.120,0:07:47.520
and the konkuamu genus and are different

0:07:47.520,0:07:49.199
from other types of hairs

0:07:49.199,0:07:51.199
as they have a small patch of reverse

0:07:51.199,0:07:52.400
barbs near the tip

0:07:52.400,0:07:54.560
and small main barbs extending the

0:07:54.560,0:07:57.120
length of the sente

0:07:57.120,0:07:58.639
even though most people are worried

0:07:58.639,0:08:00.560
about the venom of the tarantula

0:08:00.560,0:08:02.319
concern and attention should really be

0:08:02.319,0:08:04.160
paid to urticating hairs

0:08:04.160,0:08:06.160
this seemingly innocuous defense

0:08:06.160,0:08:07.360
mechanism is often

0:08:07.360,0:08:09.360
overlooked or even joked about among

0:08:09.360,0:08:11.520
tarantula keepers

0:08:11.520,0:08:12.800
but if you have ever been on the

0:08:12.800,0:08:14.800
receiving end of urticating satay

0:08:14.800,0:08:16.879
you know how irritating the reaction can

0:08:16.879,0:08:18.960
be this is why it is very important to

0:08:18.960,0:08:20.879
not place tarantulas on your face

0:08:20.879,0:08:23.120
have them around your eyes or nose and

0:08:23.120,0:08:25.199
why you definitely should never put one

0:08:25.199,0:08:26.080
in your mouth

0:08:26.080,0:08:27.919
no matter how cool you think the picture

0:08:27.919,0:08:30.080
may be and how many likes you may get on

0:08:30.080,0:08:30.879
instagram

0:08:30.879,0:08:33.039
verticating hairs in the eye can cause

0:08:33.039,0:08:34.240
temporary blindness

0:08:34.240,0:08:36.240
and may require medical treatment

0:08:36.240,0:08:38.080
getting hairs in your mouth or throat

0:08:38.080,0:08:40.000
could cause swelling making it hard to

0:08:40.000,0:08:42.719
talk eat or even breathe and the

0:08:42.719,0:08:44.560
consequences could be even worse

0:08:44.560,0:08:46.880
if they get into your lungs in all my

0:08:46.880,0:08:48.720
years of keeping tarantulas

0:08:48.720,0:08:50.480
i have found no home remedy that can

0:08:50.480,0:08:52.240
alleviate the discomfort of getting

0:08:52.240,0:08:53.600
these hairs on your skin

0:08:53.600,0:08:56.320
i have tried ice packs warm compresses

0:08:56.320,0:08:57.360
calamine lotion

0:08:57.360,0:08:59.839
duct tape hot candle wax and about any

0:08:59.839,0:09:01.839
other suggestions you can commonly find

0:09:01.839,0:09:04.800
on message boards and facebook groups

0:09:04.800,0:09:06.560
the only thing to provide the slightest

0:09:06.560,0:09:08.160
relief has been ibuprofen

0:09:08.160,0:09:10.240
benadryl and a prescription steroid

0:09:10.240,0:09:12.240
anti-itch cream my doctor prescribed

0:09:12.240,0:09:12.800
once

0:09:12.800,0:09:14.160
for the most part you just have to

0:09:14.160,0:09:15.839
suffer through the discomfort and wait

0:09:15.839,0:09:17.680
for your body to heal itself

0:09:17.680,0:09:19.680
it is best to avoid getting hair on your

0:09:19.680,0:09:21.120
skin in the first place

0:09:21.120,0:09:22.959
by taking preventative measures like

0:09:22.959,0:09:24.800
wearing gloves long sleeves

0:09:24.800,0:09:26.800
eye protection and even a face mask

0:09:26.800,0:09:28.160
depending on the species that you're

0:09:28.160,0:09:29.120
interacting with

0:09:29.120,0:09:31.130
and your sensitivity

0:09:31.130,0:09:34.169
[Applause]

0:09:35.040,0:09:36.640
now i know it sounds silly to be

0:09:36.640,0:09:38.320
concerned about hair but if you've

0:09:38.320,0:09:40.240
gotten some of that urticating set

0:09:40.240,0:09:42.399
on your skin you know how serious it can

0:09:42.399,0:09:44.160
be and it's only going to get worse the

0:09:44.160,0:09:46.160
longer you let yourself be exposed to it

0:09:46.160,0:09:47.920
now don't let this scare you or

0:09:47.920,0:09:49.519
turn you off to the hobby because

0:09:49.519,0:09:51.279
keeping tarantulas is amazing

0:09:51.279,0:09:53.839
just don't fall into that macho mindset

0:09:53.839,0:09:55.600
and throw caution in the wind and not

0:09:55.600,0:09:56.720
care about hairs at all

0:09:56.720,0:09:58.240
because as i mentioned they can be

0:09:58.240,0:10:00.320
extremely uncomfortable and potentially

0:10:00.320,0:10:02.160
dangerous if they get in your eyes nose

0:10:02.160,0:10:02.640
or mouth

0:10:02.640,0:10:04.240
as long as you wear gloves and long

0:10:04.240,0:10:06.560
sleeves and a mask and eye protection if

0:10:06.560,0:10:08.000
needed you're not going to have any

0:10:08.000,0:10:08.560
issues

0:10:08.560,0:10:10.160
