Arthropods Flashcards
Arthropod
is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages
Molting
is the manner in which an animal routinely casts off a part of its body, either at specific times of the year, or at specific points in its life cycle
Pheromones
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.
Thorax
the corresponding part of a bird, reptile, amphibian, or fish.
Abdomen
the posterior part of the body of an arthropod, especially the segments of an insect’s body behind the thorax.
Cephalothorax
the fused head and thorax of spiders and other chelicerate arthropods.
Exoskeleton
a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection.
Cheliped
one of the pair of legs that bears the large chelae in decapod crustaceans.
Malpighean tubes
are slender tubes normally found in the posterior regions of arthropod alimentary canals.
Arachnid
joint-legged invertebrate animals
Metamorphosis
the process of transformation from an immature form to an adult form in two or more distinct stages.
Crustaceans
form a large, diverse arthropod taxon which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill, woodlice, and barnacles.
Insects
are hexapod invertebrates and the largest group within the arthropod phylum
Antennae
either of a pair of long, thin sensory appendages on the heads of insects, crustaceans, and some other arthropods.
Swimmerets
a forked swimming limb of a crustacean, five pairs of which are typically attached to the abdomen.
