Phoca largha, commonly known as the larga seal, is a species of true seal found in the northern Pacific Ocean. This large seal is a prominent member of the marine ecosystem, playing a crucial role in the food chain and contributing to the biodiversity of the region. It is a fascinating and unique creature, adapted to the harsh conditions of the Arctic and subarctic.
Description & Characteristics
Phoca largha is a large seal, with adults typically measuring between 1.5 to 2.5 meters in length and weighing up to 200 kilograms. They have a robust body shape, with a thick layer of blubber for insulation in cold waters. Their fur is typically a dark gray to brown color, providing excellent camouflage in their natural habitat. The head is relatively small and rounded, with prominent whiskers that aid in detecting prey. They have large, dark eyes and small, external ears.
Habitat and Occurrence
Phoca largha is a circumpolar species, meaning it is found in the Arctic and subarctic regions of the northern Pacific Ocean. They primarily inhabit the coastal areas of Russia, Alaska, and Canada, spending much of their time on ice floes or rocky shores. The species is particularly common in the Bering Sea and the Sea of Okhotsk, thriving in the cold, nutrient-rich waters of these marine zones.
Taxonomy
Phoca largha belongs to the Class: Mammalia, Order: Carnivora, and Family: Phocidae. This classification places it among the true seals, a group of marine mammals characterized by their streamlined bodies and flippers. They are closely related to other seal species, such as the harbor seal and the grey seal.
Feeding
Phoca largha primarily feeds on fish, including small species like cod and herring. Their diet can also include crustaceans and squid, depending on the availability of prey. They are opportunistic feeders, adapting their hunting techniques based on the specific prey they are targeting.
