Deep Ocean and Marine Biology
Deep in the ocean, some creatures have adapted to the crushing pressure by ditching their bones entirely. Which animal is famous for being essentially a giant, gelatinous bladder that simply floats at great depths?
Correct
The blobfish is the ultimate professional at relaxing, as its body is composed of a gelatinous mass with a density slightly less than water, allowing it to float without wasting energy. The giant squid has a complex muscular system and a beak to hunt, so it is definitely not just a blob. The Dumbo octopus has adorable little fins and internal support structures that make it more than just jelly. As for the anglerfish, it is a ferocious predator packed with teeth and organs that would never survive as a simple floating sac of goo.
