Mike F,
In answer to you question the answer is Thornback Ray as we use common names.
However, it is really a skate........ ( I will put the scientific names on some time )
Been studying Fishbase ( amongst others ) as nothing on the TV and weather is awful etc. etc.
Sorry but I totally disagree with you M. Mike ......
If it makes it any clearer there is no such thing as a "Ray" genus
Skates and Rays are not different species of the same genus.
The genus Raja is in fact all Skates.
The family is Rajidae which is Skates and Rays.
Where's a biology teacher when you need one eh
===================================================
The species are classed as follows :-
KINGDOM = Metazoa ( Animals )
CLASS = CHONDRICHTHYES
Sub Class = ELASMOBRANCHII - SHARKS, SKATES AND RAYS
Order = RAJIFORMES = SKATES and Rays
Family = Rajidae ( Skates and Rays)
Genus = Raja (Skates)
What fish are "really" rays then ?
The Ray orders are
TORPEDINIFORMES = Electric Rays
MYLIOBATIFORMES = Stingrays and Eagle Rays
PRISTIFORMES = Sawfishes
RHINOBATIFORMES = Guitar Fishes
