Megamouth shark to be the sole extant species in the distinct family Megachasmidae, though suggestion has been made that it may belong in the family Cetorhinidae, of which the basking shark is currently the sole extant member. Researchers have predicted the feeding patterns of megamouth sharks in relation to the other two planktivorous sharks; the three plankivourous sharks have ram feeding in common, as it evolved from ram feeding swimming-type ancestors that developed their filtering mechanism to capture small prey like plankton. In addition to the living "M. pelagios", however, two extinct megamouth species – the Priabonian "M. alisonae" and the Oligocene–Miocene
Fish stringer Fish stringer A fish stringer is a line of rope or chain along which a fisherman can string fish so they can be immersed and kept alive in water. A rope stringer "(pictured)" is the simplest type of fish stringer. It consists of a line of rope or wire with a stringing needle made of metal or hardwood at one end.
