Identification: Juveniles exhibit alternating brown/white or black/white banding. White bands become brown with maturity. Body shape is long and slender. Adults are light brown to greyish brown with no prominent color patterns. Dorsal fins larger than pelvic fins. Pectoral and pelvic fins forward of dorsal fin. From Compagno and Niem (1998) and Allen et al. (2003). Similar species: Nurse shark (Ginglymostoma cirratum) has a wider head, heavier body, and uniform grey to brown coloration. Juvenile nurse sharks do not have color banding on the body.
