stay fixed in one place-SESSILE. they are animals.• Their bodies are full of pores and their skeleton invpiky (spicules) or rubbery sponging fibers. invertebrates

Front 2

Insects

Back 2

• A group of invertebrates with jointed appendages, such as claws, legs, and antennae, and a hard exoskeleton that protects the arthropod; also have bilateral symmetry. .As it grows, it molts, or sheds its old exoskeleton. • Then it grows a new exoskeleton that allows its body to continue to grow. They are the only invertebrates that can fly.

Spider

Back 6

They have 2 main body parts: a cephalothorax and an abdomen. The thorax has 4 paris of jointed legs: no antennae. They do have special mouth parts like fangs. They kill more insect pests than any other animal. As it grows, it molts, or sheds its old exoskeleton. Then it grows a new exoskeleton that allows its body to continue to grow.

Sea Star

Back 11

• Belongs to a group of invertebrates that have tiny tube feets and body parts arranges arounf a central area. Has five arms and no head. The hard, spiny covering gives the animal protection. Radail symmetry. Diet vary _ Predators, filter feeders, come eat rotting material. Spiny skin covering an internal skelation of plates. Water – vascular system to help them move and eat. Some can reproduce through regeneration from parts

Front 12

Endotherm

Back 12

an animal that controls the internal heat and produces and regulates its own temperature. its temperature is always fairly constant. they have adaptions such as sweet glands, fur, and feathers for maintaining body temperature
