Moulting is a complex process that is invariably dangerous for the arthropod involved. Before the old exoskeleton is shed, the cuticle separates from the epidermis through a process called apolysis. Early in the process of apolysis the epithelial cells release enzymatic moulting fluid between the old cuticle and the epidermis.
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
Juvenile shrimp will molt more frequently, as they must shed their exoskeleton as they grow. This discarded exoskeleton should be left in the tank, as the shrimp will eat it to recover the valuable minerals it contains. Pregnant N. davidi shrimp tend to hide in the dark. If they feel endangered by predators, they will abandon their eggs.
They are typically seen attached to substrate by their grasping appendages called the pereopods. Caprellids are omnivorous, feeding on diatoms, detritus, protozoans, smaller amphipods, and crustacean larvae. Some species are filter feeders, using their antennae to filter food from the water or scrape it off the substrate. Most species are ...
Discarded exoskeleton of dragonfly nymph Exoskeleton of cicada attached to a Tridax procumbens (colloquially known as the tridax daisy)An exoskeleton (from Greek έξω éxō "outer" [1] and σκελετός skeletós "skeleton" [2] [3]) is a skeleton that is on the exterior of an animal in the form of hardened integument, which both supports the body's shape and protects the internal organs ...
“The title of fastest punch in the animal kingdom firmly belongs to the peacock mantis shrimp, whose club-like appendages reach the speed of a .22-caliber slug, shatter clamshells with ease and ...
They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up ...
