2. Leafy seadragon (Phycodurus Eques):- These are mainly restricted to the southern Australian coast. Leafy Seadragon gets its name because of their plant like appearance. Everyone gets confused whether it is a fish or a plant. This appearance helps them to blend with their habitat and this camouflage helps them to avoid predation. When a Leafy Seadragon gets hatched, it attains sexual maturity only after 2 years.

3. Flashlight fish (Photoblepharon Palpebratum):- These are chiefly distributed in the Eastern Indian and wider Pacific Oceans. These are nocturnal fishes. During the daytime, they hide in caves or holes on the reef surface. They have specialised light organs that assist them to communicate with each other and to locate their prey.

5. Clownfish (Amphiprion Ocellaris):- These are native to Indian and Pacific oceans.  This fish cartoon is very famous among children. How can anyone forget Nemo and his Dad? These can be preserved in aquariums. Clownfish have a symbiotic association with the anemone. Anemone provides protection to clownfish. In turn, clownfish remove parasites from their body. Clownfish are protandrous hermaphrodite, meaning they can alter their sex. If the largest female dies, the male become the breeding female.
