Starting at the top of our list of craziest creatures found in the ocean is the rattail fish, known for its large eyes and mouth and a rat-like tail responsible for its name.

The Grenadier, as it is otherwise known, is a small fish that grows to a maximum length of 1.5 meters, with some smaller species growing up to 10 centimeters.

This family is so large that it makes up to 15% of the sea’s animal population. Found in depth ranges of 200-7000 meters, these fish swim in schools, especially round nose grenadiers which spend the winter in shallow waters and the summer in the deep oceans.

2. Sea cucumbers

Yes, you are absolutely right. This crazy sea creature looks exactly like cucumbers with their almost cylindrical shape and leathery skin. Coming at number nine, the sea cucumbers are small animals that grow within the range of 10-30 centimeters in length with very many species all across the world.

Their length varies with different species, with some growing to lengths of 3 meters and the largest having volumes of up to 500 cubic centimeters.

3. Deep sea dragonfish

At number 3, the dragon fish is indeed a strange creature of the sea, and TRULY a dragon of the deep sea, and its special characteristics explain it all.

From its strange appearance and adaptations, the fish is able to survive in the deep seas of up to 1500-4500 meters, and in some cases 5000 meters below the water surface.

At these depths, the pressure is crushing and the temperatures go up to -4 degree Celsius. Chances of survival are slim. For the species though, its special adaptations which include a minimal skeleton in its entire body, having jaws with which it uses to feed are enough for survival.
