Crustaceans

(Crustacea)

 

Category: Invertebrates

 

 

This very large group of arthropods includes familiar animals such as shrimp, crabs, lobsters, crayfish, and barnacles. Like other arthropods, they have an exoskeleton which they must molt in order to grow. Crustaceans are distinct in their possession of two-parted (biramous) limbs and unique larval form. They are an important source of food for humans, with over 10 million tons being produced via farming and fishing every year. Most crustaceans are aquatic, though a few are adapted to a terrestrial lifestyle.

Interesting Animal Facts

Body horror in the insect kingdom

Learning about animals, you can discover many fascinating, even beautiful facts, but there are also things that can give you nightmares! Enter the strepsiptera (“twisted-wing parasite”). The adult female has no limbs, wings, or mouth - she simply lives in and feeds off her host (typically a wasp). When it becomes time to mate, she protrudes part of her abdomen from between the plates of her host and uses mind control to get the wasp to fly off to nearby males. Sexually mature males have wings, and fly around for about five hours before dying - spending their entire short existence seeking out females to mate with. After the female is impregnated, her own young grow and consume her. And once there is nothing left to eat, they leave their host wasp, infiltrate the nursery, and latch on to a larvae to create their own “zombie wasp” host and continue the grisly cycle!
