Scientists are noticing unexpected trends in some squid populations. Scientists are surprised that the squid are gathering in new regions of the ocean. Usually, squid congregate deep in the oceans. Recently, however, a large number have been found in shallower waters off the coast of San Diego, California. Scientists have several possible theories for this occurrence. They believe that there may be a lack of food driving the squid into new areas of the ocean. The creatures may be responding to rising temperatures. Or there may be a decline in the squid's natural predators.
