20 New Sharks, Rays Discovered in Indonesia

This species of shark recently discovered in Indonesia, called a whitefin smooth hound, closely resembles similar sharks found as far away as Mexico.

Its discovery may provide important insights into the effects of fishing on shark populations, as smooth hounds are commonly caught as food.

The growing popularity of shark-fin soup in regions from China to California has caused an increased demand for shark meat, which scientists say calls for close attention to the trade's effects on shark numbers.

"Good taxonomic information is critical to managing shark and ray species, which reproduce relatively slowly and are extremely vulnerable to overfishing," said CSIRO biologist William White.

"It provides the foundation for estimating population sizes, assessing the effects of fishing, and developing plans for fisheries management and conservation."
