DNA Off Brazil Researcher Samuel Gruber explains what makes the waters around Fernando de Noronha and Atol das Rocas a great place to study sharks. A hundred miles off Brazil's northeast coast, two remote atolls rise abruptly from the Atlantic depths. Shallow havens in the otherwise deep sea, the waters of Fernando de Noronha and Atol das Rocas teem with color and life.
Lemon sharks are reasonable animals.
Nothing at all is known about the breeding strategy of requiem sharks such as the lemon shark. The lemon sharks that can be caught will be tagged in hopes to better understand and protect them. Gruber is no shark rookie. Having dedicated his life to studying the animals, he's considered one of the world's foremost shark authorities. Data from his previous research in the Bahamas will provide a good contrast to the information collected off Brazil.
