More importantly, surface clarity measured from satellites tells only part of the story. We can reduce our own pollution by properly disposing of waste and using environmentally-friendly products whenever possible. These toxins can cause serious health problems and even death. Orcas have sleek black-and-white skin which helps them camouflage when hunting prey in both deep water depths and near shorelines where light reflects off the water surface differently.The black coloring on an orcas back extends down its sides into a saddle area just behind its dorsal fin while its belly remains white; this coloration is thought help orcas blend in with both shadowed areas created by their own bodies when swimming at depth , as well making it difficult for prey species looking upwards from below to distinguish between an approaching orcas dark back against the bright sky above . This organism does the same things that sponges, sea stars, mussels, sea cucumbers, carrion, and polychaete worms are known to do. Many factors contribute to orca survival, but water clarity is a key element. Orcas are unique because they also have gills, but these are only used when the orca is young. In particular we want to look at how changes in water clarity combined with northward shifts in fish distribution affect catchability. values (darker colors) indicate lower water clarity.
