Rajella Fyllae
''Rajella fyllae'' is a species of skate (fish), skate in the family Rajidae. Name The scientific name ''fyllae'' refers to the ship HDMS Fylla, HDMS ''Fylla'', from where the holotype was collected by the ''Fylla'' scientific expeditions of 1884 and 1886 to Greenland.

The name Fylla's ray is also used, perhaps by writers who thought that "Fylla" was the name of a person. Distribution The round ray lives in the North Atlantic Ocean and Arctic Ocean.

Skate (fish)
Skates are cartilaginous fish belonging to the family Rajidae in the superorder Batoidea of rays. More than 150 species have been described, in 17 genera.LAST, P.R. & SÉRET, B. & STEHMANN, M.F.W. & WEIGMANN, S. (2016) Skates, Family Rajidae. In: Last, P.R., White, W.T., Carvalho, M.R. de, Séret, B., Stehmann, M.F.W & Naylor, G.J.P (Eds.) Rays of the World. CSIRO Publishing, Melbourne: 204–363 Softnose skates and pygmy skates were previously treated as subfamilies of Rajidae (Arhynchobatinae and Gurgesiellinae), but are now considered as distinct families. Alternatively, the name "skate" is used to refer to the entire order of Rajiformes (families Anacanthobatidae, Arhynchobatidae, Gurgesiellidae and Rajidae). Members of Rajidae are distinguished by a stiff snout and a rostrum that is not reduced. Taxonomy and systematics Evolution Skates belong to the ancient lineage of cartilaginous fishes.
