I had the opportunity to take some measurements and samples for a fisheries scientist who studies sharks. Having never dissected a shark, I soon found it was unlike anything I had ever seen up close before.
It was about nine feet long, though I later found that sleepers can grow to over 14 feet. It also had incredibly thick muscles along the spine for propelling the shark forward with powerful strokes of its tail.
Unlike most groups of fish, sharks have no swim bladders and must swim continuously to keep from sinking. Their skeleton is made entirely of cartilage, which is much lighter than bone. But this is not the only advantage the shark possesses for staying afloat.
