arthopod Flashcards
arthopod
segmented body and jointed appendages, a usually chitinous exoskeleton molted at intervals, and a dorsal anterior brain connected to a ventral chain of ganglia
molting
manner in which an animal routinely casts off a part of its body
pheromones
chemical substance that an animal or insect produces in order to attract other animals or insects and especially a mate
throrax
rib cage, which encloses the heart and lungs
abdomen
egion of the body in between the thorax and the pelvis.
Cephalothorax
tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind.
exoskeleton
external skeleton that supports and protects an animal’s body,
Cheliped
one of the pair of legs that bears the large chelae in decapod crustaceans.
malpighean tubes
type of excretory and osmoregulatory system found in some insects, myriapods, arachnids, and tardigrades.
Arachnid
four pairs of segmented legs and a body that is divided into two regions, the cephalothorax and the abdomen.
Metamorphosis
animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation.
Crustaceans
live mostly in water and have a hard shell, a segmented body, and jointed appendages.
Insects
3 legs and 2wings animal of the class Insecta, comprising small, air-breathing arthropods having the body divided into three parts
Antennae
“feelers”, are paired appendages used for sensing in arthropods
Swimmerets
adapted for swimming and for carrying eggs, as distinguished from other limbs adapted for walking or seizing.
