arthropods Flashcards
invertebrate animal having an exoskeleton, a segmented body, and jointed appendages
Arthropod
shed periodically part or all of a coat or an outer covering
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
class of joint-legged invertebrate animals
Arachnid
an eight-legged predatory arachnid with an unsegmented body consisting of a fused head and thorax and a rounded abdomen
Spiders
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 terrestrial arachnid with lobsterlike pincers and a poisonous sting at the end of its jointed tail, which it can hold curved over the back
Scorpions
any of the small paired appendages on the abdomen of crustaceans, used chiefly in locomotion and reproduction
Swimmerets
one of a pair of glands near the base of the large antennae
Green glands
A North American tick which infests wild and domestic animals
Woodtick
a plant-eating insect with long hind legs that are used for jumping and for producing a chirping sound
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
Butterfly
a common small fly occurring worldwide in and around human habitation
Housefly
a slender long-legged fly with aquatic larvae can cause diseases
Mosquito
a crustacean with a broad carapace, stalked eyes, and five pairs of legs
Crab
a large marine crustacean with a cylindrical body, stalked eyes, and the first of its five pairs of limbs modified as pincers
Lobster
