Maricorn

Maricorns are creatures with the forepart and head of a unicorn and the tail of a dolphin or fish. They have a dorsal crest from withers to the beginning of the flukes, similar to the water dragon's ridge. It can be sharp as a razor or soft like fin membrane at will, giving the maricorn an effective weapon and a safety mechanism to protect its spine. Similar to merfolk, maricorns have two forms - a water fin form (which includes cup-like fins over the front hooves, a mane like an equine, a horn of common color, and a long dolphin-like tail) and a land form (four legs and a tail like an equine). They generally lose the dorsal fin in the change to four legs, though this is pretty individual.

They lay eggs instead of giving birth to live young and royals can have clutches of anywhere from two to twelve eggs every seven months, in rare cases more or less. Common maricorns have typically one or two eggs at a setting. They are benevolent creatures by nature and enjoy having fun. The royals are marked by being either white or black with metallic horn. They can go without surfacing to breathe for a little over 20 minutes usually. Names end in "RA".
