Researchers have found that shrinking sea ice is causing polar bears to migrate to land earlier in the spring than usual and stay later into the fall. Climate change is now affecting their health and breeding success because while on land, the polar bears can’t continue to hunt and instead rely on fat reserves to survive. The longer they stay on land, the more their health suffers.

Less than a year ago, the giant squid, Architeuthis dux, was filmed for the first time in its natural habitat. Before that, parts and pieces of it had been found around the world. Now, by analyzing its DNA, scientists have discovered that no matter where it is found, it is the same species.
Many sea snakes have “comically small heads” which seems impractical, as they swallow their prey whole and many of the fish they eat come equipped with large spines. Researchers have discovered that sea snakes can evolve shrunken heads rapidly to allow them to sneak into hard-to-reach places, like eel burrows.
Back in January, we shared an article about genetically modified salmon that grow twice as fast as normal salmon. The U.S. FDA released a notice stating that it was unlikely to harm the environment or populations of natural, wild salmon. Now, several supermarket chains in the U.S., including Whole Foods Market and Trader Joe’s, have pledged not to sell this genetically modified salmon. This decision was a response to a campaign led by consumers and environmental groups opposed to the idea of eating genetically modified animals.
UPDATE — April 21
Check out this article from SeafoodSource about the “fuss” over genetically modified salmon and how we are already eating fish that are fed genetically modified ingredients.
