Some isopods are adorable. These are my favorite isopods.

Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of other woodlouse families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. It is this ability which gives woodlice in this family their common name of pill bugs, roly polies or potato bugs. The best known species in the family is Armadillidium vulgare, the common pill bug.

Woodlice in the family Armadillidiidae are able to form their bodies into a ball shape, in a process known as conglobation. This behaviour is shared with pill millipedes (which are often confused with pill bugs), armadillos and cuckoo wasps. This behaviour may be triggered by stimuli such as vibrations or pressure, and is a key defence against predation; it also serves to reduce water loss through respiration.


Genus Alpheidae

(Pistol Shrimp)

one of my favorite animals! Genus Alpheidae more commonly know as Pistol/Aplheid Shrimp with around 250 species. they are similar to mantis shrimp in a way. they are quite small growing up to 1-2 inches most of it’s size is its large claw like a fiddler crab except its not a pincer it actually has a pistol like mechanism made of two parts, a joint allows a “hammer” like part of the claw to move backward into position when the shrimp releases this it shoots a extremely powerful wave of bubbles capable of stunning fish and even breaking glass it is so loud it is around the same level as a Concorde jet during the shot for 1 millionth of a second the bubble can get as hot as the sun!! they also have a symbiotic relationship with Goby fish the shrimp shares a burrow that the goby made and the shrimp protects the goby, also the goby having better eyesight acts as a spotted alerting the shrimp to any danger who keeps contact with the fish with it’s antennae

Arachnid enthusiasts love these guys, arachnophobes not so much.. Tarantulas (family Theraphosidae) are harmless spiders with venom less powerful than a bee’s, and a semi-painful bite that should be avoided. There are various species that live in plentiful locations, and a generic statement for this species is they burrow underground. By living underground, they can sense prey approaching their burrows and will grab the prey with their appendages, injecting a paralyzing venom and then gorging themselves using their fangs. Being nocturnal hunters, they eat anything from insects to small birds. Digestive enzymes are secreted to liquefy their prey, sucking them up with their straw-like mouths. If a meal is large enough, they may not need to feast for another month. With few natural predators, the only real animal they have to be scared of is another insect, the parasitic pepsis wasp. They will paralyze tarantulas with their painful sting, and leave their eggs to not only hatch on the still living arachnid, but then feast on it afterwards. Tarantulas also lay eggs, like the wasp, but will begin with a male spinning a web and then depositing his, erm, fertilization, on the surface of the web. He’ll attempt to scuttle away before the female gets a hold of him (some aren’t lucky enough, and get eaten by the female..) and the female will seal the eggs and guard them for six to nine weeks. Once the eggs hatch, up to a thousand baby tarantulas may be crawling around.

Encountering a peacock mantis shrimp (Odontodactylus scyallarus) would be a dream come true! Travelling across the globe is a must, considering the species lives in tropical Indian and Pacific oceans. A relative of shrimp and lobsters, the brightly colored peacock mantis shrimp is a voracious predator. Its large, mobile, compound eyes have sophisticated stereoscopic and color vision that includes some ultraviolet shades. It uses sight when hunting, while waiting quietly for unsuspecting prey to come within reach, then striking using its clublike pair of legs with immense speed (75 mph) and force (100 times its own weight).
