Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Cephalurus: cephalus, from kephale (Gr.), head, referring to its expanded, flattened and rounded head; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish);  cephalus: From kephale (Gr.), head, allusion not explained, probably referring to its expanded, flattened and rounded head, “much wider” and with larger pores compared with the similar Parmaturus xaniurus, its presumed congener at the time. (See ETYFish).

Eastern Central Pacific: southern Baja California, Mexico and Gulf of California. Cephalurus specimens from Panama, Peru and Chile differ from Cephalurus cephalus and may represent one or more new species.
中太平洋東部: 墨西哥的下加利福尼亞南部與加州灣。 來自巴拿馬,祕魯與智利的 Cephalurus 標本不同於 圓頭鯊〔Cephalurus cephalus〕 而且可能是一個或多個新種。

生物学特性     字汇 (例如 epibenthic)

Found on the upper continental slope and outermost shelf. The expanded branchial region of this shark suggests that they are adapted to bottom areas with low dissolved oxygen levels. With little information available, reproductive mode could either be ovoviviparous (Ref. 244, 53776) or oviparous, paired eggs are laid (Ref. 50449).

栖息于大陆坡上层与最外的大陆棚了。 这一只鲨鱼的扩大的鳃部显示出他们用低容氧量适应底部区域。 藉由少的信息有用又生殖的模态可以或是卵胎生的 (参考文献 244,53776) 或者卵生的, 成对的卵生产.(参考文献 50449)

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Other sources describe ovoviviparity as an alternative reproductive mode (Ref. 244, 53776).中太平洋東部: 墨西哥的下加利福尼亞南部與加州灣。 來自巴拿馬,祕魯與智利的 Cephalurus 標本不同於 圓頭鯊〔Cephalurus cephalus〕 而且可能是一個或多個新種。
