Etymology: Callorhinchus: Tautonymous with Chimaera callorynchus Linnaeus 1758 (but unnecessarily emended from -rynchus to -rhinchus: callum (L.), hard skin; rhynchus (L.), snout, referring to peculiar hoe-shaped proboscis. (See ETYFish); milii: In honor of Bory de Saint-Vincent’s “old friend” (translation) Pierre Bernard Milius (1773‒1829), a French naval officer, naturalist and civil servant, who supplied specimen upon which description and its accompanying illustration (shown here) were based; (See ETYFish).

Maturity: L_m 71.0, range 70 - ? cm
Max length : 125 cm TL ذكر/ مختلط الجنس; (Ref. 26346); common length : 75.0 cm TL ذكر/ مختلط الجنس; (Ref. 9258)

Occurs on continental shelves to depths of at least 200 m (Ref. 6871). Migrates into large estuaries and inshore bays in the spring to breed (Ref. 6871). Feeds mainly on shellfish (Ref. 26346). Oviparous (Ref. 50449). Eggs are encased in horny shells (Ref. 205). Flesh is of good eating quality. Males have a small, club-like protuberance on the head and also long copulation organs near the pelvic fins (Ref. 557).
