Aspidochelone

Thick fat reservoirs and a slight buoyancy from their shells allow aspidochelones to float along the surface of the Atlantic Ocean with minimal effort. They often sleep with the top of the textured shell protruding from the ocean. The thick spines and coarse exterior are easily mistaken for a small rocky island. Many unwitting sailors dock their ships and start fires on the presumed land mass. The activity and heat wake the sea monster and it dives deep into the water, dragging both vessels and sailors to a watery grave. Due to their immense size, aspidochelones eat constantly, emitting a sweet odor through their mouth to attract large schools of fish.
