Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Seal

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Found across Europe (7 countries) and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Anchovy-Eater

The largest predatory fish on Earth, great white sharks can reach 6 meters and 2,000 kg, inhabiting cool coastal and offshore waters in all major oceans. Apex predators employing ambush attacks from below, primarily on marine mammals, large fish, and seabirds. Despite their fearsome reputation, unprovoked attacks on humans are extremely rare. Vulnerable, with populations declining from finning, bycatch, and targeted fishing despite legal protections in many jurisdictions.

Common Seal

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.
