Histriophoca fasciata, commonly known as the ribbon seal, is a species of seal found in the Arctic Ocean. It is a relatively small seal, with a distinctive pattern of dark brown and white bands that give it its name.
Description & Characteristics
Histriophoca fasciata is a relatively small seal, with males typically reaching lengths of 1.5 to 1.8 meters (4.9 to 5.9 feet) and weighing up to 140 kilograms (310 pounds). Females are smaller, averaging around 1.4 meters (4.6 feet) long and weighing up to 100 kilograms (220 pounds). The ribbon seal has a characteristic black and white banded pattern across its body, with darker bands on the back and lighter bands on the belly. This pattern is unique to each individual, making it possible to identify individual ribbon seals. They have relatively short, thick necks and small, rounded flippers.
Habitat and Occurrence
Histriophoca fasciata is a circumpolar species, meaning it is found in the Arctic Ocean around the entire globe. They are typically found in the marginal ice zone (MIZ), which is the area where the sea ice meets the open water. This habitat is critical for the ribbon seal’s lifecycle, as they use the ice for breeding, pupping, and molting. Ribbon seals are also found in coastal areas and inlets, particularly during the summer months when the sea ice melts.
Taxonomy
Histriophoca fasciata is classified within the Order Carnivora and Family Phocidae, which includes all true seals.
Feeding
Histriophoca fasciata is a carnivore, feeding primarily on fish, crustaceans, and squid. They are known to be particularly fond of cod, pollock, and shrimp. Ribbon seals hunt by diving beneath the ice and using their keen sense of smell to locate prey. They can hold their breath for extended periods, allowing them to stay submerged for several minutes at a time.
