Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Carcharhinidae
Etymology: Glyphis: Tautonymous with Carcharias glyphis Müller & Henle 1839. (See ETYFish); glyphis: Greek for knife, referring to how anterior lower teeth are serrated and flare outward, arrowhead-like, before coming to a sharp point. (See ETYFish).
More on authors: Müller & Henle.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal. Tropical; 5°N - 21°S
Western Pacific: northern Australia and New Guinea (Ref. 84281).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 244); 175.0 cm TL (female)
Found presumably inshore. Largest whole specimen collected was that of a female with maturity unknown, 175 cm TL. Large sets of jaws examined indicate that size can attain up to 2 m and possibly 3 m (Ref. 76952). Viviparous (Ref. 50449). Biology poorly known.
Life cycle and mating behavior

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00234 - 0.01075), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (90 of 100).
