Slimahacc

Rearing up before you, shedding rivers of sand from its green-scaled hide, is an extremely long serpentine creature with a bony maw and long, hollow, horn-like protrusions sweeping back and outward from the top of its scalp.

Combat
Slimahaccs normally attack only for food, and after a full meal they must rest for 2 days to digest. They need the equivalent of 2 Large creatures every third day, or 1 Large creature every day if eating on the run (a technique that avoids torpor). If cornered or trained, they will fight larger opponents but shun these otherwise, preferring to seek refuge beneath the sand and wait for the threat to pass.

Description
Slimahaccs are a sinuous species of reptile with uncertain heritage. They are also sometimes known as "sand drakes", but it is unknown if they are truly related to drakes or are instead some sort of native reptilian or "worm" offshoot. They roam the deserts, using stealth and speed to overrun and devour their prey.

Pterrans sometimes domesticate slimahaccs as riding animals or beasts of burden. While the riding position directly behind their head and an additional 10 feet of the back are relatively safe, cargo and passengers further down their back are occasionally mistaken for parasites and casually removed by the slimahacc.

In the wild, slimahaccs normally lead solitary lives hunting and sleeping. In sandy or gravelly areas, they burrow under the loose matter to a depth of about 2 feet to avoid both the heat of the day and any predators. While burrowing, slimahaccs possess tremorsense with a range of 30 ft. Above ground, the slimahacc's hearing is extremely acute. The horn-like scalp protrusions are actually powerful aural amplifiers whose wide degree of separation allows the slimahacc to triangulate the source of any sound that it can hear. It is not unusual for pterran riders to psionically link their hearing to the slimahacc they are riding in order to augment their hunting and defensive abilities.

Although rarely available for sale, a trained slimahacc will sell for as much as 40 gold pieces, ten times the price of a war crodlu. Slimahacc eggs are relatively rare and fetch a market price of 2 gp as a culinary delicacy. The "horns" of a slimahacc are actually composed of strong, hollow bone, and sections are sometimes used in constructing datchi clubs and inix yokes. Slimahacc meat is edible, though tough and muddy tasting. An adult slimahacc can grow to be over 30 feet in length.
