Mollusks
In addition to a soft body, mollusks have this thin layer of tissue that covers its internal organs.
What is the mantle?
No matter what gastropods eat, they all use this organ, a flexible ribbon of tiny teeth.
What is a radula?
One pair of legs per body segment.
What is a centipede?
This is the waxy waterproof covering of an arthropod.
What is the exoskeleton?
Crustacean larva develop into adults through this process.
What is by metamorphosis?
Most groups of mollusks have this type of circulatory system.
What is an open circulatory system?
Gastropods usually move in this way.
What is creeping along on a broad foot?
Jointed appendages define this group.
What are arthropods?
These give arthropods flexibility and the ability to move.
What are jointed appendages?
The characteristics all crustaceans share.
What is having two or three body sections, five or more pairs of legs, and two pairs of antennae?
An organ of a mollusk used for movement.
What is a foot?
Bivalves obtain food in this way.
What is filter feeding, straining tiny animals and plants from the water?
Two pairs of legs per body segment.
What is a millipede?
As a crab grows in size its exoskeleton cannot expand, therefore this process occurs.
What is molting?
Characteristics all arachnids share.
What is having two body sections, four pairs of legs, and no antennae?
This group of mollusks do not move quickly and most larva swim or float through the water.
What are bivalves?
This is the reason pearls form in an oyster.
What is sand becoming lodged between a bivalve's mantle and shell and the mantle then produces a smooth pearly cover to coat the sand or grit?
Adaptation of the cephalopod's foot.
What are the tentacles?
An arthropod may have up to three of these body sections.
What is the head, thorax and abdomen?
This is the section to which an insect's wings and legs are attached.
What is the thorax?
These mollusks have excellent vision and large brains that enable them to remember what has been learned.
What are cephalopods?
Biologists classify mollusks into groups based on these four (4)physical characteristics.
What is the presence of a shell, the type of shell, the type of of foot, and the type of nervous system?
Characteristics of insects.
What are three body sections, six legs, one pair of antennae, and usually one or two pairs of wings?
Name three (3) characteristics of arthropods are shared by ALL arthropods (extra points if you can name up to 3 more characteristics):
What is invertebrates, an external skeleton, a segmented body, jointed appendages, bilateral symmetry, and an open circulatory system?
These are the stages of an insect's complete metamorphosis.
What is egg, larva, pupa, and adult?
