Wikipedia Abstract

The shovelnose guitarfish, Rhinobatos productus, is a ray in the family Rhinobatidae.It becomes mature at an estimated seven to eight years old. Males are between 90 and 100 cm long, while females are around 99 cm at that age. The ray can live up to 11 years, and full-grown sizes are around 120 cm for males, and females reach 137 cm. They range from central California south to the Gulf of California. Morphological and genetic variations occur in the mitochondrial DNA in those found in the Gulf of California, evidencing their isolation from the rest. Because of this, the conservation of this species must be carefully managed to preserve the biological diversity. The shovelnose is considered to be a primitively developed ray, with many features of both sharks and rays.
