Description
Squatina guggenheim is shaped like a ray and in males, a spiny surface is located on its pectoral fins. However, this spiny surface is absent in females and younglings. This spiny structure is thought to help males hold females while mating. Both males and females range from 89 to 130 cm in length. S. guggenheim have 18-22 teeth in the upper and lower jaw.
