All fish are alike in three ways:
1. All fish have gills. Gills help them to breathe in water.
2.All fish have fins. Their tail fins help them to swim.
3.Fish are coldblooded. This means that their body temperature changes when the temperature of the water changes. They slow down when the water becomes cold. They move faster when the water is warm.

Angler fish
Many species are made of teeth and mouth and almost nothing else. Their stomachs can expand to hold an extra large meal.

Parrot Fish
At night, some species cover themselves in a cocoon made of mucous prior to going to sleep. This mucous is excreted from an opening on the head and wrapped around the body, masking its scent from its potential enemies and securing the fish to one spot. As if that weren’t enough, the mucous also has special restorative and healing properties, regenerating any wounds they may have sustained, and even protecting them from harmful UV rays.

Stonefish
The stonefish is the most venomous of all fish. Along its back are 13 large spines. Each spine has a pair of venomous sacs attached to it. Any light pressure on the spine will cause the sacs to eject their venom. The nuerotoxic venom causes extreme pain to humans. Other possible reactions are severe shock, heart failure and infection. Wounds obtained by touching a stonefish won't heal for months. There is an anti-venom available and scalding hot water also helps to stop the venom's activity. |
Sunfish
They have such huge bulk that you can hardly imagine how much jellyfish they must eat to survive!
