The Anatomy of a Tarantula & Spider Biology

today we are going to talk about the

anatomy of a tarantula

[Music]

welcome to tarantula collective my name

is richard and if you enjoy videos about

tarantulas scorpions and other

invertebrates and exotic pets make sure

you hit that subscribe button and don't

forget to click the notification bell to

turn on all notifications just to

reiterate i am not a biologist and i

have no scientific background i'm just a

guy that keeps and loves tarantulas and

other invertebrates as well as reptiles

amphibians pretty much any exotic pet

but my friends over at arthropods

ambassadors gave me this really cool

gift it is a 40 vision tarantula spider

model at least that's what it says here

and it's stem certified and we're going

to put this together and learn all about

the different parts of a tarantula i

don't want to dissect a real tarantula

or anything like that but i thought this

would be a good opportunity since i get

so many questions from people asking

about different names or different parts

of tarantulas now if you're not familiar

with arthropod ambassadors i will leave

a link form down below in the

description they breed and sell a lot of

mantises and isopods as well as other

invertebrates and they do a lot of

educational work so a huge thanks to

them for sending this out and if you're

interested in getting one for yourself i

will leave an affiliate link for this

product down below in the description as

well now it won't cost you anything

extra to use that link but the channel

does get a small commission from amazon

if you end up purchasing it so that

definitely helps and i always appreciate

the support but to start off what we

have is just the body of the tarantula

you know a lot of holes where stuff is

supposed to go and really the only thing

that's featured on the body that isn't

listed or broken apart are the

spinnerets which this tarantula looks to

be a brachypelma homore or a mexican red

knee tarantula they only have two

spinnerets like most tarantulas now i

think i've got it laid out correctly but

we'll find out as we put it together now

tarantulas have eight legs sometimes

people get confused because they see the

pedops and think they have ten legs but

we'll talk about that in a little bit

right now let's get these legs attached

[Music]

[Music]

now i'm noticing while putting this

together there's definitely a right and

wrong slot for the legs and each of the

little end pieces are slightly different

they got a different little shape so you

know that you're putting it into the

right hole so we got the legs on the

body and you can see there are little

nerves they have what they refer to as

the nerve cord that's running through

some of the legs which is very cool to

see again i'm just going off what is the

little booklet says inside of this i'm

not a scientist or biologist so i guess

what i'm trying to say is don't base a

research paper off of the anatomy that i

describe in this video

i'm just assuming that they know what

they're talking about so the first thing

we're going to put in here is the brain

and the eyes now tarantulas don't have a

brain like you and i do or other mammals

or even reptiles i mean you can see that

it looks a lot different and the eyes

are actually connected directly to the

brain and the eyes are referred to as a

celly which i think is how you pronounce

that but it looks like you just popped

these in here in the top

all right so we've got the eyes set in

here and then on top of the brain we

have these are actually connected

together but you can separate them but

it's the arteries and the mid-gut

branches and the sucking stomach so you

can see this sucking stomach and the

mid-gut branches which are like the

reddish orange color

and then the arteries are the greenish

piece

the sucking stomach we'll just put in

right through the eyes

[Music]

and attach it right on top of the brain

next we're going to do the cheliceric

kind of like the fang something that

most people are familiar with and

they're hollow and connected to the

venom gland which you can see this

purple venom gland here that goes down

into the fang

all right fangs are installed let's see

what's next so it looks like the next

piece is the silk glance which there are

two of them they go on either side

so we'll just pop those in there

all right so those are in and the next

piece we have is the sperm receptacle

and ovaries so obviously this is a

female that we're

assembling

[Music]

all right so we got that popped in there

now on top of that is the intestine

which has the gastric seca

casa ceca and the stur coral pocket

[Music]

[Music]

and then the last piece to put in there

is essentially the circulatory system

this is the the book lungs and the heart

the book lungs you can definitely see

here the heart is kind of in the middle

of this green part

all right so we got all of that together

so

[Music]

and then they have these cool little

see-through domes you can put on there

so that way you like the insides don't

come spilling out

all right so now we have a completely

assembled tarantula and there we go we

have it all together so we've got the

chalicerae or the fangs with the venom

gland we've got the pedopalps we've got

the four legs on each side the carapace

the abdomen and back here the spinnerets

and then just kind of break it down

further this part of the leg would be

the femur the patella

the tinta

the metatarsus

the tarsus then they don't really show

but at the end is the tarsus claw and on

the underside this would be the stem the

cephalo4x

the section where the legs kind of come

from is the coxa

then the book lungs

the epigenum

looks like right here with the

epigastric furrow

and then the crebellum

so if you want to learn more about

spider anatomy this is definitely a

pretty cool thing to pick up for

yourself or your kids or your grandkids

or if you're one of the people out there

that just love tarantulas but for

whatever reason you can't keep one on

your own i would definitely suggest

getting one of these it was it was fun

to put together i hope you enjoyed

watching me put it together though i'm

sure it'll be a lot more fun doing it

yourself and this is a massive tarantula

there's no tarantula i think it gets

this large but it definitely makes for a

cool little display piece as well as an

educational tool again if you if you

like this you want to get one for

yourself i will leave an affiliate link

for it down below in the description as

always i appreciate you watching

subscribe if you want to see more thanks

for buying tarantula collective

merchandise and i will see you next

tuesday
