Elasmobranchii (sharks and rays) > Orectolobiformes (Carpet sharks) > Ginglymostomatidae (Nurse sharks)
Etymology: Ginglymostoma: ginglymus (Gr.), hinge; stoma (Gr.), mouth, presumably referring to how corner of mouth has a hinged appearance (See ETYFish); unami: In honor of UNAM (Universidad Nacional Autónoma de México), for the “vital role it plays in educating the people of México” (translation) (See ETYFish).
Eponymy: This is an acronym of the Universidad Nacional Autónoma de México (UNAM). (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

This species is distinguished from G. cirratum by comparing several meristic characters where the distance between the prebanchial and interdorsal regions, and that of the posterior end of the second dorsal fin and the beginning of the caudal lobe, are both shorter; it also differs by the position of the insertion of the first dorsal fin with regard to the pelvic fins and in the form and number of keels on the dermal denticles and teeth morphology (Ref. 113902).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
