Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the whitesnout guitarfish; in the meantime, see the similar species.
identification
Guitarfish with a disc longer than wide and a long snout with a rounded tip, like other Pacific guitarfish. The common name comes from its pale snout. To tell it apart from the shovelnose guitarfish, which also lives in the Mexican Pacific, look at the pale snout and the depth: this species lives in very shallow water, 2 to 8 m.
