Arthropod Flashcards
an invertebrate animal of the large phylum Arthropoda, such as an insect, spider, or crustacean.
Arthropod
shed old feathers, hair, or skin, or an old shell, to make way for a new growth.
Molting
a chemical substance produced and released into the environment by an animal, especially a mammal or an insect, affecting the behavior or physiology of others of its species.
Pheromones
the part of the body of a mammal between the neck and the abdomen, including the cavity enclosed by the ribs, breastbone, and dorsal vertebrae, and containing the chief organs of circulation and respiration; the chest.
Thorax
the part of the body of a vertebrate containing the digestive organs; the belly. In humans and other mammals, it is bounded by the diaphragm and the pelvis.
Abdomen
the fused head and thorax of spiders and other chelicerate arthropods.
Cephalothorax
a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection.
Exoskeleton
one of the pair of legs that bears the large chelae in decapod crustaceans.
Cheliped
a tubular excretory organ, numbers of which open into the gut in insects and some other arthropods.
Malpighean tubes
an arthropod of the class Arachnida, such as a spider or scorpion.
Arachnid
the process of transformation from an immature form to an adult form in two or more distinct stages.
Metamorphosis
an arthropod of the large, mainly aquatic group Crustacea, such as a crab, lobster, shrimp, or barnacle.
Crustaceans
a small arthropod animal that has six legs and generally one or two pairs of wings.
Insects
either of a pair of long, thin sensory appendages on the heads of insects, crustaceans, and some other arthropods.
Antennae
a forked swimming limb of a crustacean, five pairs of which are typically attached to the abdomen.
Swimmerets
