Etymology: Loxodon: loxos (Gr.), slanting; odon (Gr.), tooth, probably referring to oblique teeth cusps [name first published with no included species; species added by Müller & Henle in 1839] (See ETYFish); macrorhinus: macro-, from makros (Gr.), long; rhinos (Gr.), nose, probably referring to its long, narrow snout (See ETYFish).
More on authors: Müller & Henle.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. A small, very slim shark with a long, narrow snout, big eyes with rear notches, short labial furrows, and small, oblique-cusped teeth with smooth edges; 2nd dorsal fin small, low and behind larger anal fin; interdorsal ridge rudimentary or absent (Ref. 5578). Grey above, pale below, fins with pale edges (transparent in life), caudal and first dorsal fins with narrow dark margin, first dorsal fin also with a dusky tip (Ref. 9997).

Found on continental and insular shelves; mainly near the bottom (Ref. 6871). Feeds on small bony fishes, shrimps and cuttlefish (Ref. 244). Viviparous (Ref. 50449); gives birth annually to litters of 2-4 pups (Ref.58048). Caught in artisanal and small scale commercial fisheries (Ref. 9997). Utilized fresh for human consumption (Ref. 244); meat and fins, but of limited value due to its small size (Ref.58048).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous, with a yolk-sac placenta; 2-4 pups per litter. Size at birth 40-43 cm; 54-55 cm TL (Ref.58048). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29, mean 28 °C (based on 1702 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00229 - 0.01045), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.4 se; based on diet studies.

Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=2).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).

Price category (Ref. 80766): Medium.
