Bathyraja aleutica
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 narrow,...

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.
