1. On April 20, 2010, an explosion on BP’s Deepwater Horizon oil rig killed 11 people and spilled at least 4.9 million barrels of oil into the Gulf of Mexico. Now, a new report from Al Jazeera says sea creatures are showing up with horrible mutations as a side effect of the spill.

    Among the disturbing mutations: Shrimp with tumors on their heads; fish that lack eyes or are missing flaps over their gills; fish with oozing sores; crabs with holes in their shells; crabs that are missing claws and spikes, or are encased in soft shells instead of hard ones.

    "I’ve never seen anything like this," Dr. Jim Cowan of Louisiana State University tells Al Jazeera. “The fishermen have never seen anything like this.”
