Introduction Coral reefs are found on the coasts of most tropical oceans. They only take up about 1% of the ocean floor, but about 25% of all marine fish live there.
Introduction The coast is a very popular place for all types of animals. Birds love the coast because there is always food. Many ocean animals will come to dry land to lay their eggs.
Introduction All fish has a spinal cord, gills (which they use to breath the oxygen out of the water), and they are covered in scales. Fish have a small brain when compared to other animals.
Introduction Nocturnal animals are mostly active at night and sleep or are less active during the day. One of the main reasons many animals choose to be active at night, is to avoid predators that may try to attack during the day.
Introduction There are different levels on the endangered scale, including extinct, critically endangered, endangered, vulnerable, near threatened, and least concern. Extinct animals are no longer living on the Earth, like the dinosaurs. Critically endangered means that animal is at an extremely high risk for becoming extinct in the wild. Endangered just means that an animal is at a very high risk for becoming extinct in the wild. The biggest threat to most animals is humans; we are destroying and taking over their habitats. Humans are also over killing and illegally hunting several endangered animals.
Introduction Animals can be dangerous for several reasons, but they usually do not harm predators or humans without a reason. Humans may threaten them, their territory, or their babies; these could be causes for the animal to attack.
