Final answer:
Squid populations are displaying unexpected trends, gathering in new regions of the ocean. Theories for this occurrence include a lack of food, rising temperatures, and a decline in squid predators.
Step-by-step explanation:
Squid populations are displaying unexpected trends, with squid gathering in new regions of the ocean. Theories for this occurrence include a lack of food, rising temperatures, and a decline in squid predators. These theories are based on the fact that squid typically congregate deep in the oceans, but recently, a large number have been found in shallower waters off the coast of San Diego, California. Researchers are studying the reasons behind this shift in squid behavior.
