The Underwatertimes has an article that purports to show a baby shark with webbed feet. Looks more like the myxopterygia (i.e., claspers, intromittent organs, valva) of an adult reef shark.
myxopterygium (mix-op-ter-ridge-ee-um): The copulatory organ or clasper of Elasmobranchii and Holocephali; rod-like extensions of the inner side of the pelvic fins. It is composed of the long stem cartilage, a shorter distal cartilage, the dorsal terminal cartilage (or rhipidion, fan-shaped for dispersing sperm in a radiating spray during copulation), the hook-shaped terminal cartilage (or claw) which has a cutting edge on its inner margin, and the narrow, sharp spur. The claw and spur serve to anchor the clasper in the female oviduct and a groove along the clasper enables the sperm to reach the oviduct. The siphon contracts to propel sperm into the oviduct.
So basically, this shark died with an erection.
Seems this story has legs and got picked up again on digg.
