Fish Fun Facts
Fishes are cold blooded like reptiles and amphibians as they cannot control their body temperature. They are vertebrate animals. Fishes make half of all known vertebrate species. They have a spinal cord surrounded by bone or cartilage. There are more than 30,000 known species of fish. Approximately 1000 of them are threatened by extinction. They have gills that are used to extract oxygen from the water around them. Starfish, jellyfish and crayfish have the word ‘fish’ in their name but they are not actually fish.
