skull

Animals that grow inside the mother's womb.
Why do we say that amphibians live a double life?
When amphibians are born they live in water and breathe with gills. They grow and change. They develop lungs and grow legs and they can live on land. Their first stage of life is aquatic and the second is terrestrial
True or False. Bats are birds.
False
What do most invertebrates have in common?
Don't have internal skeleton or backbone, all are oviparous, most are symmetrical, they can live on land and in water, they can be carnivores, herbivores or omnivores.
Some vertebrates don't have a tail. An example of a vertebrate without a tail is......
snake, frog,etc
We can classify vertebrates into 5 groups. Name them.
Birds, Reptiles, Amphibians, Fish, and Mammals
What are the characteristics of reptiles?
Live on land and in water, breathe with lungs, covered in scales, have four legs, are mostly oviparous, are mostly carnivores, lay eggs on dry land.
Explain why a platypus is a mammal.
Even though they lay eggs, once the babies are born they feed on the mother's milk.
What is an exoskeleton?
Armour plates or shells to protect the body.
Herbivores eat..................... An example of an herbivore is ........
plants and rabbits.
What is the difference between young amphibians and young reptiles?
Young amphibians live in water so they have gills to breathe and fins to move. As they become adults they develop lungs and legs.
Reptiles breathe through the lungs their entire life as the eggs are laid on dry land. They are also born with limbs, such as legs.
What are the characteristics of birds?
Land animals, covered in feathers and have wings, they have beaks, can be herbivores, carnivores or omnivores. They are oviparous and tails.
True or False. Mudskippers breathe through gills.
False
True or False. Echinoderms have soft bodies.
False. Molluscs have soft bodies
What is the difference between carnivores and omnivores?
Carnivores eat meat and omnivores eat plants and meat.
Dolphins and whales are mammals. Explain why.
They have lungs, they give birth to live babies and their offspring feeds on the mother's milk.
What are the characteristics of mammals?
Land or aquatic animals. They use the lungs to breathe. Bodies covered in fur or hair. They have limbs. Almost all mammals are viviparous. Young mammals feed on their mother's milk. Herbivores, carnivores or omnivores
An example of a poisonous mammal
Platypus
Name all the groups of invertebrates.
Cnidarians, Worms, Echinoderms, Molluscs, Arthropods, and Porifera
