These are warm blooded animals with hair who can learn and the female produces milk to feed to her young.
This is the largest of all animal phyla. They have jointed legs and the body is divided into sections. They have a hard skeleton on the outside of the body called an exoskeleton.
This kind of animal spends part of its life in water and part on land. They are cold-blooded. Their skin usually damp and smooth. They are found in wet, or damp places. Examples: frogs, toads, and salamanders.
These animals have dry scales on the skin or large plates. They have strong waterproof skin to help it live on land. They are cold-blooded. Their skin keeps water from escaping out of their body. Their eggs are tougher than amphibian eggs. Examples: turtles, lizards, snakes...
These animals are covered with feathers, have beaks, no teeth, two legs with clawed feet and wings. They are warm-blooded. They lay eggs with hard shells and most sit on their eggs until they hatch.
These animals have a slender, rounded body with pointed ends. Many of them attach themselves to a plant or animal for food. The food goes in through one hole and in the body and the waste comes out the hole in the opposite end.
These animals bodies are divided into sections called segments. They have a 3-layer body with bilateral symmetry. They have a digestive system with two openings.
These are soft-bodied invertebrates with a seashell. Some of them have internal shell-like structures.
This is a spiny-skinned animal that is usually with a star design. They have an endoskeleton usually with protective spines and tiny tube feet with suction.
Name 5 vertebrates
Some examples are: bird, cheetah, human, snake, elephant...
This is the simplest invertebrate. It's body has no symmetry. It has only 2 cell layers. It filters the water trapping tiny food particles.
This is an animal that shoots poison darts. They have poison stingers on their tentacles used to catch prey or protect themselves. They have radial symmetry, a mouth and simple tissues.
This is a more complex animal than the sponge and cnidarians. They have flat, ribbon-like bodies with a head and tail. They have bilateral symmetry and 3-cell layers.
An animal without a backbone.
An animal with a constant body temperature that does not change.
An animal with a hard covering to protect its body.
Name 5 invertebrates.
Examples: sponge, sea star, butterfly, earthworm, jellyfish, insect, and crab.....
What do we call an object or animal with no line of symmetry.
An animal whose body temperature changes according to its environment.
An animal with a backbone.
An animal with bones inside its body that support him.
Name five characteristics animals have in common.
1. They are made of many cells.
2. They reproduce.
3. They move in some way.
4. They grow and change.
5. They eat food.
Know the following steps of the food chain in the correct order...
1. Energy come from the sun.
2. Producers use sunlight to make food.
3. Consumers that eat plants are primary consumers. They use some of the energy to stay alive. The rest is lost as heat.
4. Secondary consumers get energy by eating other consumers.
5. After organisms die, decomposers like fungi and bacteria break down their remains into chemicals.
When an object or animal has two sides that are mirror images.
When body parts extend outward from a central point and match up (like a star fish).
