Making our way down into the ocean depths, I bring you the giant isopod! These creatures are related to crustaceans and pill bugs (aka, rollie pollies). They help keep the ocean floor clean by stripping all the meat possible off of fallen carcasses that reach the ocean floor.
First the Stats…
Scientific name: Bathynomus
Length: 7 – 54 inches
Lifespan: 4 years + (unknown for sure)
Now on to the Facts!
1.) These isopods, although typically scavengers of decaying flesh, will sometimes eat live prey and have been spotted trying to feast on trawl catches and eating sponges and other slow-moving prey items.
2.) Due to the great depths at which they live, these critters can go long periods without a meal. They are capable of going years without eating.
5.) When they eat they tend to eat a ton!
But wait, there’s more on the giant isopod!
6.) Since food is usually scarce, isopods live in a constant state of partial brumation.
7.) Female isopods have a marsupium (brood pouch), located on their undersides. There they hold between 20 – 30 eggs. Males have two specialized organs called peenies, that carry sperm to be delivered to the female.
Did you know…?
Like rollie pollies, they curl up into a ball when threatened and use their armor plating to help keep them safe.
8.) They use their antennae to experience the world around them and don’t really rely on their sight.
