Do you know how many feet eight hundred and twenty meters is equivalent to? The answer is two thousand, six-hundred and ninety feet. That is an example of how deep marine biologists travel to study marine animals. So being a marine biologist is neither entirely safe nor easy, but the challenges prove to be worth it because the areas they explore and the creatures that they study are utterly fascinating. Some of the animals that they’ve studied include bioluminescent jellyfish, yeti crabs, giant squid, and zombie worms.

To begin with, the bioluminescent jellyfish, yeti crabs, giant squid, and zombie worms all live in different environments and adapt to their habitats differently. Bioluminescent jellyfish are located at a depth of about 820 meters. They’ve adapted to their habitat by being bioluminescent. Often referred to as a “burglar alarm” which serves as a defense mechanism, the jellyfish’s bright lights scare predators away. Sometimes the lights will attract an even bigger predator than the one that was about to attack the jellyfish, so then the bigger predator will eat the fish that was planning on killing the jellyfish. Yeti crabs are located near the Antarctica in the Southern Pacific; 7,200 feet below the surface are a chain of hydrothermal vents. They pile up around the thermal vents while waving their claws simultaneously. Supposedly scientists think that their thriving depends on mineral eating bacteria that might grow on the crabs’ hairs and that the crabs collect the bacteria.
