Part of the reason why life under the sea is so interesting is because there are many species down below that we have never even heard of! Take a look at some…
Eunice aphroditois--bobbit worm (aquatic, predatory, polychaete worm. It as has one of, if not the, longest bodies among the polychaete worms – their average length is one metre, and specimens measuring a whopping three metres have been discovered in the waters of the Iberian Peninsula, Australia and Japan.)
Rarely growing larger than a foot (30 centimeters) in length, the Axolotl is one of nature’s smaller bundles of amazing. A critically endangered species thanks to water pollution and predatory introduction in their native Mexico, these amphibians are a species of salamander that never undergoes metamorphosis and therefore remains gilled and aquatic for its entire life.
The Oarfish is a rare, solitary, and giant denizen of the ocean depths (arguably larger than a Whale Shark. (The Oarfish,17m as opposed to the Whale Shark, 12.96m in the Guinness Book of World Records.)) and is a filter feeder, comfortable cruising at depths of 200 m. Mistakenly named for its prominent pectoral oars with which it was thought to 'row', it undulates serpentlike with its dorsal fins and has been seen orienting itself vertically. This is a rare photo.
