Bilaterally paired small, rodlike cartilages on the ventral surface of the abdomen (present at 7.9 mm). Their posterior tips expand laterally, forming L-shaped cartilages. Medially, a posterior spur of cartilage develops, which will later ossify as the ischiac process (Weitzman 1962). [ http://zfin.org/curator ]
