Axolotls live between 550 to 7020 feet deep underwater. In fact, they are called giant for a reason, some of these creatures can grow absolutely gigantic! Their enormous size helps them to compromise the pressure of the deep ocean.
They nearly exclusively eat carrion, and when something edible is found on the ocean’s floor, they eat a lot of it because they don’t always know when their next feast will be.
Isopods have extremely slow metabolisms and they may not need anything to eat for a few years thanks to this unique ability.
