Etymology: Carcharhinus: karcharos (Gr.), sharp or jagged; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, both words alluding to a shark's jagged, rasp-like skin (See ETYFish)sealei: In honor of American ichthyologist Alvin Seale (1871-1958), Stanford University, who described this shark in 1910 but used a preoccupied name (C. borneensis) (See ETYFish).
Eponymy: Alvin Seale (1871–1958) was an ichthyologist and designer of aquaria. [...] (Ref. 128868), visit book page.

Biologi     Ordlista (t.ex. epibenthic)

Found on the continental and insular shelves, from the surf line and intertidal region to deeper water (Ref. 244). Feeds on small bony fishes (including sea horses), prawns, and squid (Ref. 9997). Viviparous (Ref. 50449). Specimens caught with size ranging from 37.0-67.4 cm TL were found to be immature, males apparently begin to mature around 71.0 cm TL and birth size is between 32.0 and 37.0 cm TL (Ref. 89954). Often caught by shore anglers (Ref. 5485). Utilized as a food fish (Ref. 244).
