Descriptions of skate egg cases (Chondrichthyes: Rajiformes: Rajoidei) from the eastern North Pacific Author Ebert, David A. Author Davis, Chante D. text Zootaxa 2007 1393 1 18 journal article 10.5281/zenodo.175296 e2a01bd5-e044-4bd8-bfbe-e95cb0480f75 1175­5326 175296 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 ).
