The most defining part of an Ethetinae is of course their beautiful shell. The lower part of the shell often has an azure blue colour and is filled with irregular gold patterns. Nobody exactly knows why the Ethetinae have these patterns or what puropose that they serve, but some theories suggest that they receive these from absorbing Water Magic
. The top of the shell is slightly more protruding and has a white colour. When the Ethetina uses Water Magic
this part of the shell is said to glow.
The front of the creature shows part of its exposed mollusk body. The lower tentacles are used to get food and bring it to the mouth. On the top of its head there are two antennae which it uses to sense magic around it.
For its regular food intake the Ethetina uses its tentacles to catch small fish or plankton. Sometimes it uses its Water Magic
abilities to alter the current around it and move its pray towards its tentacles.
Besides its food needs, the Ethetina also has to renew its magical supply from time to time. It is for this reason that the Ethetina are so commonly found near Sea Falls
. It uses its antennae to touch the crystals and absorb some of its magic. The amount they absorb is so small that the Sea Falls
are never depleted by this action.
