 The sixgill stingray has a bulky , flabby body with a rounded pectoral fin disc that is longer than wide . The triangular snout is much longer in adults than in juveniles ( making up almost two @-@ fifths of the disc length ) , and is filled with a clear gelatinous material ; because of this , the snout of a dead specimen can shrink significantly when exposed to air or preservatives . The tiny eyes are placed far apart and well ahead of the larger spiracles . Between the widely spaced nostrils are a pair of short and fleshy flaps that are joined in the middle to form a curtain of skin . The mouth is wide and nearly straight . In either jaw are 44 – 102 rows of small , blunt teeth arranged in a quincunx pattern ; the teeth are more numerous in adults . Six pairs of small gill slits occur on the underside of the disc ; all other rays have five pairs ( a few sharks also have six or more pairs of gill slits , for example in the genus Hexanchus ) . One recorded specimen had six gill slits on the left side and seven on the right . Their pelvic fins are rather large and rounded .
