Arthropods Flashcards
an invertebrate animal of the large phylum Arthropoda, such as an insect, spider, or crustacean.
arthropods
(of an animal) 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
an eight-legged predatory arachnid with an unsegmented body consisting of a fused head and thorax and a rounded abdomen. Spiders have fangs that inject poison into their prey, and most kinds spin webs in which to capture insects.
spiders
a change of the form or nature of a thing or person into a completely different one, by natural or supernatural means.
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 terrestrial arachnid with lobsterlike pincers and a poisonous sting at the end of its jointed tail, which it can hold curved over the back. Most kinds live in tropical and subtropical areas.
scorpions
another term for pleopod.
swimmerets
one of a pair of large green glands in some crustaceans (such as crayfishes) that have an excretory function and open at the bases of the larger antennae.
green glands
Any of various ticks of the genus Dermacentor that occur in wooded areas, infest mammals, and transmit the microorganisms that cause Rocky Mountain spotted fever and tularemia in humans.
woodtick
a plant-eating insect with long hind legs that are used for jumping and for producing a chirping sound. It frequents grassy places and low vegetation.
grasshopper
an insect with two pairs of large wings that are covered with tiny scales, usually brightly colored, and typically held erect when at rest. Butterflies fly by day, have clubbed or dilated antennae, and usually feed on nectar.
butterfly
a common small fly occurring worldwide in and around human habitation. Its eggs are laid in decaying material, and the fly can be a health hazard due to its contamination of food.
housefly
a slender long-legged fly with aquatic larvae. The bite of the bloodsucking female can transmit a number of serious diseases including malaria and encephalitis.
mosquito
a crustacean with a broad carapace, stalked eyes, and five pairs of legs, the first pair of which are modified as pincers. Crabs are abundant on many shores, especially in the tropics, where some have become adapted to life on land.
crab
a large marine crustacean with a cylindrical body, stalked eyes, and the first of its five pairs of limbs modified as pincers.
lobster
