[I discovered this creature doing an image search for the alicanto, and was immediately enamored of this horrible disease-ridden pig-seal. Most of the best information on it is in Spanish–thank god for Google Translate!]
Cuchivilu This horse-sized beast resembles
an elongated, serpentine pig. Its forelimbs end in stout cloven hooves, but its
hind legs are little more than stubs.
Many
strange and terrible creatures live in the sea, but it is especially terrible
when they do not stay there. The cuchivilu is a foul hybrid creature that is as
common on shorelines and in estuaries as it is in the ocean deeps. A cuchivilu
is malicious in the extreme, and delights in killing more than it can consume.
A cuchivilu’s presence is revealed by massive fish kills and may be mistaken
for a red tide, but no red tide can tear apart fishermen or beachcombers with
disease-dripping tusks.
Cuchivilu
prefer to lair in sea caves or other submerged dens, as the suffocated victims
of marine life wandering into their cursed auras provides them with easy meals.
Their lairs are desolate, lifeless places, although aquatic undead often are
attracted to the anoxic zones cuchivilu create and cohabitate with them. Cuchivilu
are solitary creatures and only tolerate each others’ company briefly to mate.
A cuchivilu is clumsy on land, but will not hesitate to leave the water to kill
or avoid being killed. On land, they move with vertical motions like an immense
caterpillar, anchoring themselves with their hoofed forelegs. Marine humanoids
such as merfolk and locathah despise cuchivilu, and even evil creatures like
sahaugin may ally temporarily with other races to exterminate a cuchivilu.
A
cuchivilu grows up to twelve feet long and weighs 3000 pounds.
Cuchivilu are found throughout the Swirling Sea. They are rather rare due to the fact that no other sea-dwellers tolerate their presence, even evil creatures like calafex rakshasas and wastriliths.
