Species Watch: Sharks Collapsing, Turtles Fighting Back

There's mixed news on the species conservation front. In the Mediterranean, evidence shows shark populations are being decimated while a rare turtle returns to Texas after a 70 year hiatus.

The populations of five shark species (including hammerheads, pictured) have been slashed by 96 percent over the past two centuries,
reports the NY Times. This is especially hard since sharks take a while to reach sexual maturity and they only have one offspring at a time. Overfishing seems to be the culprit.

Across the globe, along the Gulf Coast in Texas, the leatherbacks are back. For the first time since the 1930s, biologists have found evidence of leatherback turtles crawling ashore and laying eggs. Leatherbacks can grow up to six feed long and weigh a ton.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
