Two years after the massive Gulf of Mexico oil spill, scientists say they're finding trouble with sick fish that dwell along offshore reefs and in the deep waters - especially in places where the oil spill hit the hardest.

The scientists are unsure what's causing a small percentage of the fish they're catching to have large open sores and strange black streaks. The biggest question is whether contaminants from the BP spill are causing the problems.

According to a lengthy report by Al-Jazeera English, Gulf Coast fishermen as well as scientists have found "disturbing numbers of mutated shrimp, crab and fish."
