  2. (narrator) Where do
    big reef fish go to hide,
  3. especially from threats
    such as overfishing and pollution?
  4. The Academy's Hudson Pinheiro
    has found that in many cases
  5. the fish head to deeper waters
  6. to an area of coral reefs
    known as the "Twilight Zone."
  7. Hudson calls it a "refugium."
  8. The refugium hypothesis predicts
    that mesophotic reefs,
  9. like the Twilight Zone,
    can work as an area
  10. where bigger fish are
    most commonly found there.
  11. It protects some fish and species
  12. that can contribute to the recovery
    of the shallow-water fish.
  13. (narrator) But the Brazilian scientist
    has found that it depends
  14. on how close the deep reefs are
    to shore and to human populations.
  15. Because the platform shelf
    of Bermuda is very long,
  16. the human impacts that happen
    more close to the coast
  17. don't breach these deep reefs
    that are situated far from the coast.
  18. In Curaçao, the deeper reefs were
    very, very close to the coast,
  19. so the human impacts were more likely
    to reach these depths.
  20. (narrator) Armed with this information,
  21. Hudson and his colleagues
    can help protect all of these areas.
  22. (Hudson) In some works
    that we did in Brazil,
  23. we found that many of the deep habitats
  24. were not inside
    current marine protected areas,
  25. so we started to propose
    the expansion of these protected areas.
  26. In the Philippines, we recently
    presented our dataset
  27. for the local managers there,
  28. and showed the importance
    to protect these deep fishes....
  29. and now they are planning to expand
  30. the marine protected areas there, too.
  31. In different areas that we visit,
    we are trying to send our data
  32. as fast as we can to the managers,
  33. and try to work together with them
  34. in order to answer these questions
  35. or fill some gaps of information
    and try to expand
  36. the actual marine protected areas
    for these deep reefs as well.
