The Science Behind the Science
The main difference between reptiles, amphibians and fish is down to their breathing mechanism. Reptiles breathe in oxygen from the air, fish breathe in oxygen from water and amphibians are able to do both.
Despite this, all three are cold blooded animals, which is also known as endothermic animals. Millions of years ago, amphibians and reptiles evolved from fish, which is why they have so many similarities, such as endothermism and scales.
Some species of reptile live in water or around water and they are able to hold their breath for long periods of time. For example, sea kraits are a species of snake and they can hold their breath for an hour before they need to come up for air.
Explore and use classification keys to help them group, identify and name a variety of living things in their local and wider environment and put vertebrate animals into groups, for example: fish, amphibians, reptiles, birds, and mammals; and invertebrates into snails and slugs, worms, spiders, and insects.
The study of the characteristics, systems, and behaviours of humans and other animals, and of plants; the interactions and relationships between and among them, and with the environment.
