The two species of panrays are generally poorly known and one of the species was only scientifically described in 2016.[1][6] They are up to about 60 cm (2 ft) long, and brownish above with a heavily mottled, blotched or barred dark pattern. They are ovoviviparous and feed on benthic invertebrates.[1]
