Tentacruel are dangerous.

They live far out in the ocean and hunt large animals like Whales and even Gyarados.
Both have been found with large sting scars on their bodys where they have been attacked but failed.
The 'teeth' in an elongated beak. It is used to grip hold of prey while the stingers do the rest.

Tentacruels long tenticles drift beneith it as it waits for prey to accidentally swim into the forest of stinging vines.
They can make themselves look almost invisible by controlling the light that enters their translucent bodies.
Prey wont see them untill its too late.

In mating season they come together and flash at one another with their large red bulbs which have been named by sailors as the 'Rubys of the sea' or 'Devils eyes'. They are called the 'Devils eyes' because sometimes they mistake boats for food and drag them down into the sea.

Their sting can kill a full grown man instantly, so if training one you must know what your doing and should never capture on from the wild as they hardly ever listen to commands.
