Jul 22, 2019 · Why are sea lions endangered? Sea lions around the world are endangered, in part due to humans hunting them in the 19 th century, where whole colonies were wiped out. Sealing stopped in Australia in the 1920s, but population numbers of all pinnipeds have taken a long time to recover.
Sea lions (and fur seals) are distinguished from true seals by their comparably large front flippers, visible ear flaps, and ability to curl their back flippers under their body to walk on all fours. Sea lions are vocal, expressing themselves in loud barks.

There are several species of ice-associated seals including bearded seals, ringed seals, spotted seals, ribbon seals, harp seals, and hooded seals. They are generally found in the Arctic, and depend on sea ice for at least part of the year to rest, breed, nurse and rear pups, molt, and avoid predators. However, the warming climate is changing the r...
Hawaiian monk seals are one of the most endangered seal species in the world and one of NOAA Fisheries’ Species in the Spotlight. They are found almost exclusively in the Hawaiian Archipelago. Hawaiian monk seals spend time on small low-lying islands to give birth, nurse their pups, and escape predators such as sharks. Climate change impacts includ...
Guadalupe fur seals live and breed on small rocky islands off southern California and the Pacific coast of Mexico. These areas are susceptible to warming waters, ocean acidification, and harmful algal blooms, all of which are increasing in frequency due to climate change. Guadalupe fur seals mostly eat squid and may be unable to adapt their diet to...
The effects of climate change on marine species and habitats will continue and increase in the coming decades. NOAA Fisheries is committed to our mission to conserve protected species in the face of these threats. With our partners, we have taken a series of steps to advance climate-focused science and management including: 1. Climate vulnerability...
Seals and sea lions are still in need of protection. Hundreds of seals and sea lions are killed each year by human-related activities, ranging from the unintended consequences of entanglement in fishing gear and vessel strikes to intentional shootings. [13] Federal law recognizes the important role of seals and sea lions in their ecosystems.
Oct 27, 2018 · In our region, researchers are working to address the basic understanding gray seals- from what they eat, to where they go, how they interact with fisheries, how human behavior alters seal behavior, and how they contribute to ecosystem function.
Seals are found along most coasts and cold waters, but a majority of them live in the Arctic and Antarctic waters. Harbor, ringed, ribbon, spotted and bearded seals, as well as northern fur seals and Steller sea lions live in the Arctic region.

Mar 23, 2011 · For more than 10,000 years, Native Americans from Alaska to southern California relied on aquatic animals such as seals, sea lions, and sea otters for food and raw materials. Archaeological research on the interactions between people and these marine mammals has made great advances recently and provides a unique lens for understanding the human ...
