An Ocean That’s No Longer Wild
At the very least, tens of millions of sharks killed are every year, mostly for their fins. At the most, that number is closer to 100 million. In this interview, Simon Thorrold, a biologist at Woods Hole Oceanographic Institution, explains the situation with sharks and how tagging projects can aid conservation efforts.
Coincidence or trend? Second oarfish washes ashore in California
People are going to stop believing that oarfish sightings are rare if this keeps happening. A second giant oarfish washed up on a Southern California beach less than a week after the first. The 14-foot-long oarfish washed up along Oceanside, California on Friday and was discovered by a group of third-graders on a beach study trip. Now scientists are trying to determine if this is just a coincidence or a trend.
I Don’t Think You’re Ready for This, Jelly
Did you know that jellyfish have been orbiting Earth since the early 90s? To study the effects if weightlessness, NASA launched into space 2,487 jellyfish polyps that eventually became more than 60,000 jellies. The end goal of the experiment was to see how the jellyfish developed without gravity and how they would respond once back on Earth. Jellyfish were used because they, like humans, orient themselves according to gravity. It turns out that the space jellies didn’t develop that gravity-sensing abilities and they had trouble getting around once back in gravity.
