This is a creature from the Astraeos Mythological Creatures mod

Level 224

Gliding through shallow kelp forests and sparkling coral reefs, the Seahorse (Hippocampus mythica) presents a surreal sight: the front half resembles a graceful horse, while the rear tapers into a powerful finned tail, shimmering with bioluminescent patterns. Despite its delicate appearance, the Seahorse is no stranger to evasive maneuvers. When startled, it releases a harmless cloud of iridescent mist and vanishes into underwater foliage. Though non-aggressive, these creatures remain elusive and are rarely encountered near populated shores.
