Some fish can swim backwards. The diet of the flying fish mainly consists of small crustaceans and planktons. Stingrays use electric sensors to find food. This enables it to find its prey even if it is burried in the sand. The flying fish are attracted to light. This habit allows fishermen to catch them easily. At night many Parrotfish secrete and then sleep inside a mucous cocoon. This cocoon protects it from parastes and snails, also helps it warn about the presence of predators and adds a horrible taste and smell to the parrot fish thus keeping the predators at a safe distance. Some fish species are able to change their sex. Clown fish is a classic example of this, they are all born males and the dominant males change their sex during the course of life. Bettas breathe air. If they don't breathe air they will drown. Male betta fish builds a bubble nest for the arrival of eggs. The Salmon fish spends most of its time in the ocean but comes back to the freshwater for spawning. Oils from orange rough which is a deep-sea fish, are used in making shampoos.

Amphibian facts What Makes an Amphibian? Amphibians are animals that live part of their lives in water and part on land.  They usually have soft, moist skin that is protected by a slippery layer of mucus. They also tend to live in moist places or near water to keep their bodies from drying out. There are three main groups of amphibians: caecilians; salamanders, newts, and mudpuppies; and frogs and toads.

Reptiles Dry leathery skin Small brains Several dozen of eggs Cold blooded

Facts about Reptiles Reptiles are found in every continent except Antarctica. Reptiles have existed for more than 300 million years. There are more than 8000 reptile species in the world. Reptiles are lizards, snakes, turtles, and crocodiles as well as the lesser-known groups of tuataras. Reptiles have scales or horny plates that cover their body. You will often find reptiles lying in the sun on rocks and logs. They can rarely breath underwater. Reptiles are called cold-blooded because they can't regulate their own body temperature. Their body temperature is dependent on the external temperature. Most reptiles lay eggs which have leathery shells that are resistant to drying.

Birds Feathers Beak besides teeth (they don’t chew) Dozen or so eggs

Bird facts Birds have feathers, wings, lay eggs and are warm blooded. There are around 10000 different species of birds worldwide. The Ostrich is the largest bird in the world. It also lays the largest eggs and has the fastest maximum running speed (97 kph). Scientists believe that birds evolved from theropod dinosaurs. Birds have hollow bones which help them fly. Some bird species are intelligent enough to create and use tools. The chicken is the most common species of bird found in the world.
