Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

This species is characterized by the following: disc approximately 2.2-2.4 times as broad as it is long, the maximum disc width size approximately 550 cm; slender whip-like tail approximately 123% of disc length if intact; no distinct caudal spine or cartilaginous mass at base of tail; some specimens have small hump at the base of the tail on the dorsal surface, while others have a slight depression and groove on the dorsum of the tail immediately posterior to the posterior margin of the dorsal fin; small, knob-like dermal denticles evenly distributed on both the dorsal and ventral surfaces, with ventral surface having slightly larger denticles; dental ligament with small cusped teeth on the lower jaw measuring roughly 22% of total disc length, approximately 6-8 rows, 142-182 files across entire width of the tooth band; total tooth counts of 900-1500 for entire tooth band; top jaw lacks rows of enlarged denticles (Ref. 82755).
Body shape (shape guide): other.

Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults are commonly sighted inshore, within a few kilometers of land; found around coral and rocky reefs as well as along productive coastlines with consistent upwelling, tropical island groups, atolls and bays (Ref. 82755). Maximum movement recorded is >500,000 m (Ref. 97317). Known aggregations include sites in Hawai'i, Mozambique, Maldives, Ryukyu Island, Yap Island, Indonesia, eastern and western Australia (Ref. 82755). Gestation period is 12-13 months. Major food consists of planktonic organisms and probably small bony fishes (Ref. 114953). Maximum correted to 450 cm WD by Giuseppe Notarbartolo di Sciara (pers. Comm. 01/2025).
