Ixitxachitl

An ixitxachitl, or ixixachitl, also known as demon ray, was an aquatic creature resembling a manta ray. Ixitxachitls were evil servants of Demogorgon that dwelled in the oceans of Toril.

Combat
Ixitxachitls preferred to ambush their prey in groups, lying in wait underneath the sea floor.

Society
The labyrinthine dens of ixitxachitls were typically dug–out from coral reefs with the help of slave labor. Their surrounding environment were often left devoid of all plant and wildlife.

Groups were led by the strongest among them through intimidation. This position was most often taken up by clerics or a vampiric ixitxachitl.

Relationships
Ixitxachitls were largely hated by other aquatic life due to their avaricious behaviors and practice of slavery. They were typically known to wage war for territory and feeding grounds against the sahuagins, locathahs, merfolk, and coastal human settlements. With Merrow they had an intense rivalry over which of them were the superior servant of the Demogorgon.
