Callorhinchidae (Plownose chimaeras)
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).

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).
生活于大陆棚到深度至少 200 公尺。 (参考文献 6871) 在春天游进大的河口与近海海湾内繁殖。 (参考文献 6871) 主要吃贝。 (参考文献 26346) 卵生的.(参考文献 50449) 卵被包在角状的外型突起中。 (参考文献 205) 肉是有好吃的品质。 在腹鳍附近的头部以及长的链接器官上雄鱼有一个小又棍棒状的突起。 (参考文献 557)

Migrates into large estuaries and inshore bays in the spring to breed (Ref. 6871). Oviparous, two egg cases (Ref. 26346) are laid on sandy or muddy bottoms and take up to 8 months to hatch (Ref. 6871). Embryos feed solely on yolk (Ref. 50449).Young hatch at about 15 cm (Ref. 26346).西南太平洋: 澳洲南部與紐西蘭。
