Detailed explanation-1: -Eastern North Pacific gray whales migrate annually between wintering grounds in the lagoons of Baja California, Mexico, and summer feeding grounds in the Arctic. This migration follows the coast of North America and overlaps with areas of heavy coastal shipping, commercial fishing, and resource exploration.

Detailed explanation-2: -In the winter, these eastern gray whales migrate south along the west coast of the US to Mexico to breed and have their calves. The calm, warm waters of the lagoons are a safe place for young whales, free from predators like killer whales.

Detailed explanation-3: -There are several reasons behind whale migration. The two main reasons for whale migrations are feeding and mating. During the warmer months, whale feeding sources can become scarce. This leads to whales migrating to colder waters where food sources have not been exhausted and are plentiful.

Detailed explanation-4: -Overall Body and Skin Adaptations: s long, sleek torpedo shape is perfect for swimming and diving with less drag and more speed. The whale’s skin excretes tiny droplets of oil that decrease drag even more. The outer layer of the skin is shed rapidly, which also helps reduce drag.
