Celebrated on June 18th
Fish can form schools containing millions of fish. They use their eyes and something called a lateral line to hold their places in the school. The lateral line is a row of pores running along the fish’s sides from head to tail. Special hairs in the pores sense changes in water pressure from the movements of other fish or predators.
We use the term ‘Fish’ when we refer to only one species of fish like 10 Shark are 10 fish while the term ‘Fishes’ is used when we refer more than one species like 10 Shark, 2 Salmon, and 4 Trout are 16 fishes.
The mudskipper fish has the ability to spend half of its time outside of the water and actually use its fins to ‘walk’ on land. It breathes out of water in two ways: through a portable water supply that is maintained in its gill chambers and also through wet skin pores.
