sharks off antartica

Apparently sharks, crabs and other predators are returning, or are about to, off the coast of antartica. Can you guess what may be the cause of this? Did someone say global warming? If you did, you'd be right. The 1degree warming every 25 years is tipping the scale back in favor of large sea predators which for 40 million years were kept at bay by ice cold water temperatures.

"We expect the populations (of seafloor invertebrates) to take a dive," said one marine biologist. (discovery news)
