The Crabeater Seal – Lobodon carcinophagus is a species of seal found in the Southern Ocean. It is one of the most abundant marine mammals on Earth, with an estimated population of over 15 million individuals.
Description & Characteristics
The Crabeater Seal is a relatively small seal, with adults typically measuring between 2.2 and 2.6 meters in length and weighing around 200 kilograms. They have a distinctive, slender body shape with a long, pointed head and a short, blunt muzzle. Their fur is short and dense, with a greyish-brown coloration that may appear darker in certain lighting conditions. One of their most notable features is their distinctive, narrow jaws with rows of small, sharp teeth, perfectly adapted for filtering krill from the water.
Habitat and Occurrence
The Crabeater Seal is a highly specialized species, adapted to thrive in the cold, icy waters of the Southern Ocean. Its range encompasses the Antarctic continental shelf and the surrounding islands, making it a prevalent presence in these aquatic ecosystems. They are often found in pack ice, where they can access their primary food source – krill.
Taxonomy
The species Lobodon carcinophagus belongs to the Class: Mammalia, Order: Carnivora, and Family: Phocidae. It is classified as a true seal, a group characterized by their lack of external ear flaps and their streamlined body shape, which allows for efficient swimming and diving.
Feeding
The Crabeater Seal is a carnivore and a highly specialized predator. Its diet consists primarily of krill, small crustaceans that form a significant part of the Southern Ocean ecosystem. They are adapted for filtering krill from the water, using their unique teeth to strain out the tiny crustaceans. While they do consume some fish, their primary food source remains krill, making them crucial to the balance of the Southern Ocean ecosystem. They are known to dive to depths of around 300 meters in search of food.
