简单描述 型态特徵 | 形态测量图

脊椎骨: 36 - 38. Somniosus antarcticus differs from S. pacificus by the following characters: interdorsal space about 80% of prebranchial length (vs. 70%); height of first dorsal fin about 3.0% of precaudal length (PCL) (vs. 3.7%); height of second dorsal fin about 2.9% of PCL (vs. 3.4%); number of turns in spiral valve 36-41 (mode 39) (vs. 32-37, mode 33); precaudal vertebrae 30-31 (mode 30) (vs. 28-30, mode 29) (Ref. 50224).
