Mermaid Apparition in The Waves

Looks an orca or dolphin.

In folklore, a mermaid is an aquatic creature with the head and upper body of a female human and the tail of a fish.[1] Mermaids appear in the folklore of many cultures worldwide, including the Near East, Europe, Asia, and Africa.

In ancient Assyria, the goddess Atargatis transformed herself into a mermaid out of shame for accidentally killing her human lover. Mermaids are sometimes associated with perilous events such as floods, storms, shipwrecks, and drownings. In other folk traditions (or sometimes within the same tradition), they can be benevolent or beneficent, bestowing boons or falling in love with humans.

The male equivalent of the mermaid is the merman, also a familiar figure in folklore and heraldry. Although traditions about and sightings of mermen are less common than those of mermaids, they are generally assumed to co-exist with their female counterparts. The male and the female collectively are sometimes referred to as merfolk or merpeople.
