During our excursions, we spotted the porpoise. This aquatic animal, known for its speed, poses a major challenge for both amateur and professional photographers. Capturing a sharp image of this cetacean is rare and requires great skill.
Besides the porpoise, the region is also home to sea lions and seals. Sea lions, recognizable by their external ears and long flippers, are often seen lounging on the rocks. Seals, with their streamlined bodies, excel in the water and are less frequently seen on land.
Porpoise (Phocoenidae)
Family: Phocoenidae (toothed cetaceans)
Size: 1.5 to 2.5 meters
Weight: 50 to 200 kg
Characteristics:
Small cetaceans resembling dolphins, but with a short snout and spade-shaped teeth.
Discreet: Often swim alone or in small groups, avoiding boats.
Iconic species:
Harbor porpoise (Phocoena phocoena): North Atlantic, threatened by gillnets.
Vaquita (Phocoena sinus): Critically endangered (fewer than 10 individuals).
Diet: Fish, squid, and crustaceans.
Conservation status: Varies, but several species are threatened by bycatch and pollution.
Sea lion (Otariidae)
Family: Otariidae (eared pinnipeds)
Size: 1.5 to 3 meters
Weight: 100 to 1,000 kg (males are much larger)
Characteristics:
Powerful front flippers: Can "walk" on land.
Social: Live in noisy colonies, with harems dominated by a single male.
Agile predators: Hunt fish, squid, and sometimes penguins.
Well-known species:
California sea lion (Zalophus californianus): Common in zoos and marine parks.
Steller sea lion (Eumetopias jubatus): Largest species, in decline in the North Pacific.
Conservation status: Some populations stable, others in decline (hunting, climate change).
Seal (Phocidae)
Family: Phocidae (earless pinnipeds)
Size: 1 to 5 meters (depending on species)
Weight: 50 kg to 3.5 tons (elephant seal)
Characteristics:
Rear flippers oriented backward: Move poorly on land (unlike sea lions).
Deep divers: Some (like the Weddell seal) dive to 600 m.
Iconic species:
Monk seal (Monachus spp.): Critically endangered (Mediterranean, Hawaii).
Gray seal (Halichoerus grypus): North Atlantic, expanding population.
Diet: Fish, crustaceans, sometimes penguins.
Conservation status: Varies, but several species threatened by hunting, pollution, and melting ice.
