Redspotted catshark
The redspotted catshark, ''Schroederichthys chilensis'', also known as the Chilean catshark, is a species of catshark commonly found in the coastal waters of the southeastern Pacific, from central Peru to southern Chile. They are typically found in the rocky sublittoral areas at the edge of the continental shelf, in waters down to 100 m in depth. They spend the spring, summer, and fall in rocky subtidal areas, but winter in deeper offshore waters due to the strong currents at that time of year.
==Description==
Redspotted catsharks range in length from 30 to 66 cm, although these sizes are taken from captured sharks, and it is believed that they may grow larger than this.
Their bodies are elongate and sleek, typical of the catshark family. Their dorsal side is a dark reddish brown with dark saddle patterns on their side. Their ventral sides are a creamy white with reddish spots. Redspotted catsharks have two dorsal fins, with the first dorsal axil over the pelvic region. Their dorsal fins do not have spines, and their tails have no upward bend.
Redspotted catsharks have multicuspid teeth. However, males typically have longer teeth with fewer cusps. This is believed to aid in courtship biting.
