For the best experience, please use a modern browser such as Chrome, Firefox, or Edge. The male elephant seals can grow to 4 metres in length, and weigh around 2,300 kg. As human interactions with seals and sea lions increase, so does the risk of disturbing or injuring these animals. The projected increase in vessel traffic arising from the opening of trans-polar shipping routes (as arctic sea ice continues to decline) will increase the risk of vessel strikes and also increase ambient noise and pollution. This dataset follows Northern elephant seals and Sooty Shearwater seabirds. Overseeing marine mammal health and stranding response. A colony of elephant seals that took over a popular tourist beach in a Californian national park during the recent US government shutdown have given birth to … Elephant seals migrate so that they can move to warmer waters and stay away from prey. The elephant seal tagging efforts to date have provided a detailed understanding of their movement patterns, unparalleled among open-ocean species. During the molt, these animals fast and lose weight. Threats such as disease, contaminants,and entanglement. During the winter months they migrate north to South America. Technically, the waters that are extremely deep for air-breathing divers, between 200-1,000 meters deep, are at midwater depths with respect to the total depth of the oceans. Females travel further and for longer on their second migration, after their molt. What scientists have found is consistent with feeding in midwater and benthic environments. Never approach or try to save an injured or entangled animal yourself—it can be dangerous to both the animal and you. Populations of northern elephant seals in the U.S. and Mexico were all originally derived from a few hundred individuals surviving in Mexico. It is believed that only about one percent of all male elephant seals actually get to mate during their life. This species will haul out during molting season and may stay in the same area for weeks at a time. Elephant seal make this migration twice a year, also coming back to the rookery to Human beings shed hair and skin all the time, but elephant seals go through a catastrophic molt, in which the entire layer of epidermis with the hairs attached is sloughed off in one concentrated time. Learn more about how to safely and responsibly view seals and sea lions, Learn more about the rules regarding feeding and harassing marine mammals in the wild. Pregnant elephant seals arrive at the rookery for the purpose of giving birth, and often do so within two days of their arrival. Though they range as far north as Alaska and as far south as Mexico, they typically breed in the Channel Islands of California or Baja California in Mexico. Northern elephant seal cools off in the sun with cold sand. The cephalopods include mid- and deep-dwelling squid and octopus, the fishes include deeper and bottom-dwelling fishes such as Pacific hake (Merluccious productus), and mid-water crabs such as tuna crabs. Northern elephant seals were once thought to be extinct due to commercial sealing in the 1800s. It is also the only mammal known to undertake two migratory journeys annually. The largest colonies of northern elephant seals are found off southern California in the Channel Islands. Over the two migrations, northern elephant seals travel linear distances of at least ~21,000 km for males and ~18,000 km for females during 250 (males)- 300 (females) days at sea [31]. Southern elephant seal . Elephant seals migrate in search of food, spending months at sea and often diving deep to forage. Polar-orbiting satellites like the ARGOS satellite orbit the Earth in about 90 minutes. World map providing approximate representation of the northern elephant seal's range. Northern elephant seal post-molting migration. Molting takes from 4 to 5 weeks to complete. They look shaggy and unkempt as they lose sheets of fur and epidermis before growing new skin and silvery new fur. New satellite-based technologies make it possible to track animals at sea. Their prey is dominated by deeper dwelling species that includes cephalopods, fishes and crustaceans. Call the NOAA Fisheries Enforcement Hotline at (800) 853-1964 to report a federal marine resource violation. Adult males use their large, inflatable noses during the winter breeding season to resonate sound when vocally threatening each other. The southern elephant seal (Mirounga leonina) is one of two species of elephant seals.It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest extant marine mammal that is not a cetacean.It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. Both Asian and African elephants migrate and generally follow the same migratory routes annually. They go to forage and build up energy reserves that allow land-based activities while fasting for 2-4 months. Elephant seal food preferences aren't entirely clear because each new study still reveals new food preferences [28][29][30]. The results of this research are used to inform management decisions and ensure stable population levels for this species. Image courtesy photographer - Nichole Dillon-Lee. Scientists in our Marine Mammal Laboratory conduct wide-ranging research on the biology, life history, and health of northern elephant seals including: Learn about our northern elephant seal research. Rough annual schedule for California rookeries. Females generally live for about 19 years, while males only live for about 13 years. Adult males may grow to over 13 feet (4 m) in length and weigh up to 4,500 pounds (2,000 kg). Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. Elephant seals that are outfitted with satellite tags can be tracked. Marine debris, Alaska, Basic measurements include water depth and temperature. It’s a short walk from the Chimney Rock parking lot to the elephant seal overlook. Photo: NOAA Fisheries/Eric Boerner. Now about 17,000 elephant seals call this beach their home. (GA image) Sneaker males hang out along the periphery of the rookery and try to mate when the harem master is asleep or busy.
