Brown smooth-hound

[10] The shark is generally found in enclosed, shallow, and muddy bays and has the largest distribution in its genus in the eastern Pacific.

[4] The shark travels an average of 15.3 km per day as part of these migrations and has the ability to cover long distances through continuous swimming.

[18] A 2017 research study on food resource partitioning habits found that the species almost entirely feeds on Teleostei and that there was significant dietary overlap between juveniles and adults as well as males and females.

There have been no clear signs of population declines on account of the shark being fished in low volumes by recreational anglers and due to the species’ comparatively high fecundity and early maturation age.

[11] This species is not heavily pursued by any particular fishery and any accidental commercial catches are sold at low prices.

[8] There are very few threats facing this species since it is not caught in large numbers by recreational anglers and since bycatch comprises a majority of its commercial landings.

[6] The shark derives its ecological and fishing importance from the fact that it is a mesopredator, meaning that it occupies a trophic level in around the middle of the food web.
