Though it’s easy to see that our domesticated four-legged friends have quirky personalities, new studies show that some ocean animals may just have their own, too. And not only do some animals have unique personalities, but their disposition may just play unique evolutionary roles.

- This past weekend, more than 45 endangered Kemp’s ridley sea turtles became stranded on Cape Cod beaches after suffering from hypothermia. Animal strandings are typically a bad thing, but in this case, say scientists, strandings mean that the sea turtles can be rescued before dying from hypothermia. The Boston Globe

- In a new study, researchers say that identifying scars on humpback whales from killer whales and cookiecutter sharks is helping scientists better understand their migration patterns. Because cookiecutter sharks are typically found in warmer waters, whereas killer whales are widely distributed, scars from cookiecutters show that humpbacks recently passed through warmer waters.

Illegal and unsustainable fishing activity is taking a tremendous toll on the world’s oceans, stripping them of healthy fish populations and damaging precious ecosystems. Not only does the United Nations Food and Agriculture Organization estimate that nearly one-third of assessed marine fish stocks have been overfished, but they also estimate that 90 percent were either fully fished or overfished in 2011.
