Description
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, 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. Posterior apron straight, broad, transverse, posterior horns longer than anteriors and about 90% or more length of egg case, tapering towards tips with tendrils coiling towards filamentous tips. Color after preservation a golden brown, lighter along lateral keels.
Remarks: A common species in the Bering Sea and Gulf of Alaska its southern range is now known to extend into northern California (Hoff, 2002; Ebert, 2003).
