General Arthropod
The type of circulatory system Arthropods have
What is an Open Circulatory System?
Shrimp-like crustaceans which make up a huge percentage of the biomass in the oceans. They are the key link in the food chain for marine life near Antartica.
What are krill?
Arthropods with one or two body sections and clawlike appendages for grabbing and immobilizing prey.
What are horseshoe crabs and arachnids (spiders, ticks, mites, and scorpions)?
The most abundant animals in the world.
What are insects?
The type of skeleton of Arthropods
What is Exoskeleton?
The appendages near the mouth used by crustaceans to crush food.
What are the mandibles?
Appendages that chelicerates use to eat, mate and sense their environment.
What are pedipalps?
The number of pair of antennae in insects.
What is one pair?
The layers of carbohydrate substance which make up the suit of armor for arthropods
What is chiton?
The crustacean cephalothorax is covered by this single plate.
What is a carapace?
Type of eyes with only one lens which chelicerates have.
What are simple eyes?
Insects are often classified by the number, arrangement, and kind of these.
What are wings?
Periodical shedding of the skeleton to allow for growth.
What is molting?
The first three pairs of crustacean walking legs exhibit these claws.
What are chelipeds
Organ for breathing found in land-bound chelicerates.
What are book lungs?
The respiratory system for an insect is made of these tubes.
What are tracheae?
The type of appendages of arthropods which enable movement.
What is jointed?
The 3 uses of chelipeds in crustaceans.
What are capturing prey, defending against predators, grooming, and sparring?
Organ for breathing in aquatic chelicerates.
What are book gills?
Insects are able to use these, besides antennae, for smell and taste.
What are feet?
The type of eyes of crustaceans and insects which contain thousands of lenses which give it an almost 360 degrees field of view.
What are compound eyes?
Pairs of flipper-like appendages extending from the abdomen of crustaceans.
What are swimmerets?
A system by which spiders can get rid of nitrogen-containing wastes without losing necessary water.
What are malpighian tubules?
Chemicals released to indicate a readiness to mate, or to communicate about danger or food sources.
What are pheromones?
The three body divisions of a typical Arthropod.
What are the cephalothorax, thorax, and abdomen?
The number of pairs of walking legs in most crustaceans.
What are five?
An organ used by spiders to spin silk.
What are spinnerets?
Female insects lay their eggs through this extension of their last body segment.
What is an ovipositor?
The two components of the arthropod nervous system which function as a brain.
What are a pair of ganglia and two major nerves?
The number of sets of antennae on a crustacean.
What are two?
Type of reproduction in aquatic chelicerates.
What is external fertilization?
Three characteristics of insects. (Hint: number of segments and walking legs are two of them)
What are three body segments, six walking legs, and wings?
These are located in the head region and give information about taste, smell, and touch.
What are the antennae?
Type of eyes in crustaceans.
What are compound eyes?
Type of reproduction in terrestrial chelicerates.
What is internal fertilization?
An insect begins as a larva that bears little resemblance to the adult form. The larva molts and becomes a pupa, from which it transforms into the adult form. (egg,larva, pupa, adult)
What is complete metamorphosis?
The largest phyla in the kingdom Animalia.
What is Arthropoda?
Enable the crustacean to change color in order to blend into their surroundings or to communicate.
What are chromatophores?
Two kinds of chelicerates that typically live as parasites.
What are ticks and mites?
An insect passes through a series of stages, called nymphs, which resemble the adult form, between molts. They do not pass through a pupal stage of development.
What is incomplete metamorphosis?
