Large sharks benefit from marine reserves

Current research has shown that waters off Florida and the Bahamas are important pupping and feeding grounds for several sharks, providing them with the critical habitat required for the conservation of these slow-to-mature ocean animals.

Researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science studied the core home range of 86 bull, great hammerhead and tiger sharks tagged in waters off south Florida and the northern Bahamas.

Stewart Island shark cage diving creates controversy

A New Zealand parliamentary select committee has raised concerns about the potential human risk from shark cage diving around Stewart Island. The Local Government and Environment Committee published a report considering a petition calling for the Department of Conservation (DOC) to immediately and permanently cease shark diving. The petition was created by Stewart Island resident Helen Cave and signed by 768 people.

Although Bull sharks have been implicated in many attacks on bathers, divers are normally not harassed unless they are spear fishing.

New Strategy for Embryo Nourishment Found in the Tiger Shark

Drs. José I Castro, Keiichi Sato, and Ashby B. Bodine, have discovered a new method of embryonic nourishment in sharks. The tiger shark secretes a nutritive liquid which fills the egg sacs where the embryos are growing, permitting higher numbers of offspring to attain a large size. Their paper, entitled "A novel mode of embryonic nutrition in the tiger shark, (Galeocerdo cuvier)," has just been published in the journal Marine Biology Research.
