What WWF Is Doing. Sea lions often rest aboard fishing boats, sometimes causing the boats to sink. Fishermen try to prevent them from coming aboard by putting up barbwire as a barrier, but this causes severe injuries to the sea lions. WWF helped support a project on San Cristóbal Island that built and installed two floating bases for sea lions ...

The genetically isolated Australian sea lion is believed to number 6,500 mature individuals in a decreasing global population throughout Western and South Australia and is endangered by the IUCN and on the state level within its existing range. Similarly, the Galapagos sea lion jumped from vulnerable to endangered by the IUCN in 2008 and is fully p...
Sea lion species are vulnerable to pollution, climate change, bycatch, and diseases introduced by other species. Complications from gillnet fishing represent a considerably significant threat to both Australian and New Zealand sea lions, while Galapagos sea lions are more susceptible to climate change, disease, and pollution.
Like seals, sea lions belong to a group of marine mammals known as pinnipeds who live primarily in the ocean but are able to come on land for long periods of time thanks to their adapted "foot-like" flippers. Because of this, they're not the easiest to count, identify, and monitor. Scientists in Glacier Bay, Alaska, are using a combination of count...
Sea lion. Sea lions are pinnipeds characterized by external ear flaps, long foreflippers, the ability to walk on all fours, short and thick hair, and a big chest and belly. Together with the fur seals, they make up the family Otariidae, eared seals. The sea lions have six extant and one extinct species (the Japanese sea lion) in five genera.

As marine mammals, sea lions spend time in the water and on land, and they usually live and hunt in large groups. However, during the breeding season, only the dominant males are allowed to pair up and mate. They compete for dominance, and the winner couples with an average of 16 females during the season. Sea lions are predators.
May 13, 2022 · New Zealand sea lions, Phocarctos hookeri, also known as whakahao/rāpoka, are the rarest species of sea lion in the world, and the most threatened because of their declining numbers. The IUCN added the New Zealand sea lion to the endangered list in 2015, whilst there were just 3000 individuals left in total, predicting a 98 percent probability of extinction within the next five generations.

Seals and sea lions belong to a group of marine mammals called pinnipeds, which means fin or flipper-footed. These animals live in the ocean, but are able to come on land for long periods of time. Some species have evolved the ability to hold their breath for up to two hours and dive to depths of more than 6,500 feet when looking for food.
