Hippocampi

Hippocampi share a common ancestor who was deeply affected by water magic. They will always possess two forms that they are able to shift between: a land form for traversing terrain, and a water form that allows them to swim and breathe underwater.

The aquatic half of a hippocampus can be based on fish, cetaceans, octopi, seals, or any other marine creature. And yes, you can also just 'make up' the fish half, there doesn't need to be a real-world equivalent!

Hippocampi are usually omnivorous, but they adapt well to any diet.

A hippocampus can have an affinity for water or vapor.

Pure hippocampi always have:


 * a land form.
 * a water form.

Hippocampican have (in both forms):


 * fangs.
 * fins and scales.
 * a fishtail.
 * stingers, tentacles, barbels - anything that correlates to their aquatic animal(s) really.
 * bio-luminescence.
