Exposure to organochlorines known to affect health impacts in other species have been found in parts of the western and eastern DPSs, though impacts on Steller sea lions are not clear. Brazilian Porcupine: Beautiful and Threatened, Save the Vaquita: On the Brink of Extinction, Discover the Little Known Aristocrats of the Animal Kingdom. Incidental take due to interactions with active fishing gear, (PDF: see Table 10).

Californian sea lion. Entanglement, Most parts of the range of the western DPS are not systematically monitored for carcasses, so there are no current studies on evaluating levels of illegal shooting; large parts of the fishing industry, including fisheries near Steller sea lion rookeries, haulouts, and feeding areas, have either no or very limited observer coverage. WWF helped support a project on San Cristóbal Island that built and installed two floating bases for sea lions to rest on and a “primary care nursery” for sea lions and other species.

Because of unexplained widespread population declines in Alaska, listing the eastern distinct population segment (DPS) as threatened and the western DPS as endangered.
Federal agencies that undertake, fund, or permit activities that may affect these designated critical habitat areas are required to consult with NOAA Fisheries to ensure that their actions do not adversely modify or destroy designated critical habitat. Data show that the foraging ranges of the two DPSs overlap, especially in the non-breeding season. Take a closer look at these encyclopedia books including information about animal habitats, behavior, and scientific classification.

They also use their swimming strengths for survival by hunting hake, sardines, squid and red octopus. The decline in the abundance of Steller sea lions was first observed in Alaska in the 1970s, and the rate of decline increased dramatically in the late 1980s. Historically, Steller sea lions were highly abundant throughout many parts of the coastal North Pacific Ocean. Come with us on an unforgettable journey behind the scenes during a SeaWorld or Busch Gardens Camp. We are required by the…. While there is likely much less shooting than during the period of sharp decline in the 1970s and 1980s, recent documented increases in the Copper River Delta area, as well as fishermen’s reports of greater interactions with fisheries leading to increased anger towards the species, are cause for concern.
Thus, we are highly uncertain about the size of this threat. About The Species. This is true especially in the most remote parts of the range of this species. Diving ability changes with age. Below are some species: 1.

As a result, the stock is classified as a "strategic stock". E, In Alaska, report a sick, injured, entangled, stranded, or dead marine mammal to the Alaska Marine Mammal Stranding Hotline at.

Internet Explorer lacks support for the features of this website. They may frequent sandbars; sheltered coves; tide pools; and structures such as piers, jetties, and buoys. Our scientists collect information and present this data in annual stock assessment reports. The sea lion’s body has adapted so that it can retain its body heat even when submerged in water and at low temperatures.
This species is very intelligent and is therefore a popular choice for theme park shows. Both adult males and females have light blonde to reddish brown coats that are slightly darker on the chest and abdomen. Sea lions range mainly from light to dark brown, with a streamlined body.
