In some invertebrates and outer covering that protects their bodies. EX. exoskeleton or shell.		PROTECTIVE COVERING
Is a hard covering that some invertebrates (bivalves) and mammals (tortoise) have.		SHELL
Articulated protective covering that arthropods have,Can be thick or thin.		EXOSKELETON
Animals adapted to live in water most of its life.		AQUATIC ANIMALS
Animals that live in the sea		MARINE ANIMALS
Animals adapted to live in fresh water, as lakes or rivers.		FRESH WATER ANIMALS
Animals that live during all or most of their life on land		TERRESTRIAL ANIMALS
The top layer of the earth's surface (ground)in which plants can grow, and some animals live.		SOIL
Tinny holes on the skin of some invertebrates (sponges), that filter the nutritive substances in seawater.		PORES

is the name of the limbs that we can find in some aquatic inverterbrates such as octopuses, cuttlefish or jellyfish.		TENTACLES
These invertebrates have got poisonous tentacles and jelly-like bodies. They are aquatic.		JELLY FISH
soft body invertebrates, most of them protected with one or two shells. Some could live on land but most are aquatic.		MOLLUSCS
They have got soft body protected by two shells. They are aquatic		BIVALVES
They are terrestrial or aquatic. Some of them have got a single spiral shell to protect them.		GASTROPODS
They have got limbs with suction caps. Their limbs grow from their heads. They are marine animals		CEPHALOPODS
Round shallow cups that we can find around the cephalopds tentacles.		SUCTION CAPS
Invertebrates with and skeleton made of hard plates, or spines. Some have got five limbs called rays. Others got spines and round shape. Are marine animals.		ECHINODERS
Is the name of the protective covering that forms the rays of an star fish.		HARD PLATES
It is a pricky and pointed part of some echinoderms. They use it to move with it and to protect their bodies.		SPINES
The name of the limbs of an starfish. Most of them got five of them.		RAYS
Invertebrates with and skeleton made of spines and round shape. Are marine animals.		SEA URCHINS
Invertebrates with and skeleton made of hard plates. Some have got five limbs called rays.		STAR FISH
Invertebrates with an arituclated exoskeleton, and a segmented body. Most numerous group of animals on earth.		ARTHROPODS
These invertebrates are the most numerous on Earth. They could be terrestrial or aquatic. They have got six legs and two or four wings. Most have two antennae.		INSECTS
Three main parts that divide the body of an insect.		-HEAD -TORAX -ABDOMEN
Transformation process during which a larvae hatch from an egg and throughout some stages become an adult insect		METHAMORPHOSIS
Arthropods with eight legs but without antennae. Some of them, produce silk to make webs		ARACHNIDS
Arthropods with a hard exoskeleton. They have got antennae. Many of them have got ten legs. most of them are marine animals, but there are also freshwater and terrestrial.		CRUSTACEANS
Arthropods with long bodies made up of many identical segments. Each segment has got one or two pairs of legs. They have got also a pair of antennae		MYRIAPODS
These invertebrates have got a long and soft body. They haven’t got legs, and no protective covering		ANNELIDS OR WORMS
