Vertebrates (Back Bone)

Amphibians - Moist skin -lay eggs in water -eggs coated in jelly



**Amphibians** (class Amphibia), such as frogs, toads, salamanders, newts, and caecilians, are ectothermic (or cold-blooded) animals that metamorphose from a juvenile water-breathing form, to an adult air-breathing form.

Birds -Feathers -Eggs have a hard shell -warm blooded



**Birds** (class **Aves**) are winged, endothermic (warm-blooded), vertebrate animals that lay eggs. There are around 10,000 living species, making them the most numerous tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic to the Antarctic.

Reptiles -dry scales - eggs have a leathery shell


 * Reptiles**, or members of the class Reptilia, are air-breathing, generally "cold-blooded" amniotes whose skin is usually covered in scales or scutes. They are tetrapods (either having four limbs or being descended from four-limbed ancestors) and lay amniotic eggs, in which the embryo is surrounded by a membrane called the amnion.

Fish -have wet scales -live in water -have fins to move -breathe using gills



A **fish** is any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in fresh water, with species being known from mountain streams ( as well as in the deepest depths of the ocean.

Mammals -hair -give birth to live young -produce milk -warm blooded

**Mammals** (formally **Mammalia**) are a class of vertebrate animals whose females are characterized by the possession of mammary glands while both males and females are characterized by sweat glands, hair, three middle ear bones used in hearing, and a neocortex region in the brain.
