Bathyraja aleutica Gilbert 1896
Bathyraja aleutica (Gilbert, 1896) Description : The egg cases of Bathyraja aleutica (Figure 3) are very large,> 120 mm in length, with MAW about 73–76% of ECL. Egg case surface very coarse, striated, and with long anteriorly directed prickles giving it a velvety texture. Lateral keels very narro...

Egg case surface very coarse, striated, and with long anteriorly directed prickles giving it a velvety texture. Lateral keels very narrow, about 6–7% of MAW. Attachment fibers present, originating near base of posterior horns. Anterior apron border broad and concave, similar in width to the posterior. Anterior horns relatively short, about 60–80% of ECL, curved inwards, tapering towards tips, becoming thin and filamentous.
