Pricklefin

Pricklefins are solitary creatures, known for their unique defense mechanism. When threatened, they can rapidly tense their muscles, causing their dorsal spines to stiffen and protrude, making them an unappetizing target for larger predators. Unlike true dolphins, they are less social, preferring to patrol their territories alone, using a modified form of echolocation that produces a series of high-pitched clicks and low-frequency grunts, allowing them to navigate murky waters and locate prey hidden in the seabed.

Their preferred habitats are shallow, murky coastal waters where the seabed offers ample foraging opportunities. They spend their days meticulously sifting through sand and mud with their sensitive snouts, often rolling onto their sides to expose their ventral spines, creating a disruptive profile against the seafloor. While primarily aquatic, Pricklefins have been observed briefly beaching themselves in secluded coves to rid themselves of parasites, a behavior rare among marine mammals.
