Isn’t nature amazing? Just when you think you had heard it all, up pops something new and weird created by nature.
Check this out. Tawny Sharks dancing.
The tawny nurse shark is a species of carpet shark in the family Ginglymostomatidae. It is found widely along coastlines in the Indo-Pacific, preferring reefs, sandy flats, and seagrass beds from very shallow water to a depth of 70 m.
According to livescience.com: “Twenty wriggling tawny sharks (Nebrius ferrugineus) were recently caught on video undulating on a beach on Mer Island, Australia.But why were the sharks shimmying in the sand? Though the sharks were gathered in shallow water, they weren’t stranded or in distress. Rather, their sinuous moves dug up tasty marine clams known as pipis (Paphies australis, the name “pipi” comes from the Māori language), which were buried in the wet sand.”
Tawny nurse sharks are quite commonly encountered by divers. They can be seen lying on a sandy floor or huddled together in their favorite cave or crevice during the day. As they are nocturnal creatures, they can best be seen hunting when night diving. As a member of the nurse shark family, they are easily recognized by their elongated tail the thin, fleshy, whisker-like organs on the lower jaw in front of the nostrils. These protuberances provide their sense of taste and touch. They are not known to attack humans.
