描述：

Description: The strongly triangular body shape, short tail, low number of thorns on the tail, absence of thorns on the disk, and eyes set far apart - are all consistent with Bathyraja richardsoni. Pale coloration is also right. Depth occurrence is OK. But, the most definitive character is the position of the pelvic fins. Very few skates have the pelvics situated wholly or nearly-wholly behind the disk. B. richardsoni is one that does - and so is the fish in this photo.
