About the Gorgona Guitarfish

Pseudobatos prahli, also known by its common name Gorgona guitarfish is a species from the genus Pseudobatos. It is distinguished from other members of the genus by its coloration and rostral cartilages, and is native to the eastern Pacific Ocean.

The Gorgona Guitarfish is a benthic, coastal marine batoid (ray/skate) that has a body type similar to others in its genus; flattened with symmetric dorsal fins, a pointed snout, a long, asymmetrical tail with no lower lobe, and a triangular body. P. prahli can be distinguished from other guitarfishes by its distinct coloring and rostral cartilages. Its dorsal side is brown with white spots and speckles, darker brown splotches, and its ventral side is tan. The brown coloration appears during early stage embryonic development, with the dots only appearing in late stage development. The rostral cartilages are unique for being widely spaced and converging at the tip of the snout in a round shape [4]. This guitarfish is a medium-sized fish, but has a large size variation. Its minimum and maximum recorded weight is 540g and 2220g, respectively.

Typically the size range is from 50 cm TL to 90 cm TL, but the average size... Wikipedia →
