Biodiversity and systematics of skates (Chondrichthyes: Rajiformes: Rajoidei),or collaboration have accounted for 78 of the 131 species described since 1948 and for nine of 13 genera named since 1950. Furthermore, detailed regional surveys and accounts of skate biodiversity have also contributed to a better understanding of the diversity of the skates.

Southern African skate biodiversity and distribution,opes, and none are confined to inshore environments. Skate diversity increases on the outer shelves and upper slopes. At least half of the skate species are endemic to the southern African region; other species also occur off East or West Africa, a few extend to European waters, and records of one s性学院 发表于 2025-3-27 09:42:31

Comparative feeding ecology of four sympatric skate species off central California, USA,ially shrimps and euphausiids) less important in the diets of large individuals. Crabs contributed substantially to skate diet compositions on the shelf, but were uncommon prey items at deeper depths, probably because of their relative scarcity in slope waters. Conversely, cephalopods were common pr多余 发表于 2025-3-28 02:23:58
Standardized diet compositions and trophic levels of skates (Chondrichthyes: Rajiformes: Rajoidei),composition data revealed four major trophic guilds, each dominated by one of these prey groups. Fish and decapod guilds were dominant comprising 39 of 48 species analyzed. Analysis of skate families revealed that the Arhynchobatidae and Rajidae had similar TL values of 3.86 and 3.79 (.-test, . = 0.ABYSS 发表于 2025-3-28 08:06:28
