(Ground sharks) > Carcharhinidae
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); hemiodon: hemi-, from hemisys (Gr.), half; odon (Gr.), tooth, allusion not explained, perhaps referring to how teeth on upper jaw are serrated basally and smooth distally. (See ETYFish).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; amphidromous (Ref. 51243); depth range 10 - 150 m (Ref. 106604). Deep-water; 25°N - 13°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 9997)
A little-known shark found on the continental and insular shelves (Ref. 244). Reports from river mouths and rivers are based on old records that need verification (Ref. 9997). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 9997). Viviparous (Ref. 50449). Utilized fresh for human consumption (Ref. 9997).
