Etymology: Cephaloscyllium: cephalus, from kephale (Gr.), head, referring to its very broad and depressed head; skylion, Greek for dogfish or small shark. (See ETYFish); silasi: In honor of Eric Godwin Silas (1928-2018), Sri Lankan-born Indian ichthyologist and fisheries scientist, Director, Central Marine Fisheries Institute (India), “whose excellent publications on the ichthyofauna of the continental shelf of the south-west coast of India have added much to our knowledge of the fauna of this region”.

This is a small shark with the following characters: stout body with expanded belly; labial furrows absent but a vestigial lower labial furrow may be present; anterior nasal flaps are broadly triangular; head depressed, flattened and broad, rounded in dorsal and ventrally; mouth large and arched; 5 gill slits, dorsolaterally placed and last two gill slits over pectorals, the 1-3 gill slits are subequal in length, 5th smallest; eyes dorsolateral and slit like; large mouth, arched or crescentic; mouth width 0.6 times HL; first dorsal origin slightly in front of pelvic insertion and placed above pelvics (Ref. 95495).

Found on the uppermost continental slope. Probably a dwarf species. Oviparous (Ref. 50499). This species could possibly attains a maximum size of 50.0 cm TL, with males reported (Ref. 26842) to reach length at maturity at 36.7 cm TL. A 45.0 cm female was found gravid and have two egg cases, one in each uterus, containing visible embryos (85.1-86.2 mm) with attached yolk sac. Stomach examined contains crustaceans and cephalopods (Ref. 95495).
