These pinnipeds live along the rocky Pacific Ocean coastlines of western North America. They are very social animals and form groups of several hundred individuals onshore. In many areas they have become quite invasive and obnoxious. California sea lions are the most recognized pinniped species because they are commonly seen doing acrobatic tricks in shows at zoos and aquariums. While they are known for their intelligence and playfulness, these animals also quite athletic. In the wild, the California sea lion swims up to 25 miles per hour, which is faster than any other sea lion or seal. This superb speed is related to how they use their front flippers.

The Greeks associated them with both the sea and sun and were considered to be under the protection of the gods Poseidon and Apollo. Pinnipeds can be found in facilities around the world, as their large size and playfulness make them popular attractions. Zoologist Georges Cuvier noted during the 19th century that wild seals show considerable fondness for humans and stated that they are second only to some monkeys among wild animals in their easily tamability. Francis Galton noted in his landmark paper on domestication that seals were a spectacular example of an animal that would most likely never be domesticated despite their friendliness and desire for comfort due to the fact that they serve no practical use for humans. Some modern exhibits have rocky backgrounds with artificial haul-out sites and a pool, while others have pens with small rocky, elevated shelters where the animals can dive into their pools. More elaborate exhibits contain deep pools that can be viewed underwater with rock-mimicking cement as haul-out areas. The most common pinniped species kept in captivity is the California sea lion as it is both easy to train and adaptable. Other species popularly kept include the grey seal and harbor seal. Larger animals like walruses and Steller sea lions are much less common.

  • DENR Information Sheet Template
    Australian sea lions Australian sea lions (Neophoca cinerea) are part of a group known as ‘eared’ seals. A male (bull) sea lion has brown fur and a blonde mane and can weigh up to 300kg, while the female (cow) weighs less than a quarter of this weight and has a light brown back and yellow belly. It is an ‘eared’ seal, as can be seen by its ear flaps. It differs from earless or ‘true’ seals such as leopard seals, which have no external ear flaps and cannot use their hind legs when on land. Pups can be born at any time of the year after an 18-month gestation – the longest of any type of seal. The mothers nurse their young for at least 18 months after they are born. Australian sea lions are listed as rare on the IUCN Red List. They are also listed as endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999, and are protected in South Australia under the National Parks and Wildlife Act 1972. Commonly asked questions Where are Australian sea lions found? Sea lions are unique to South Australia and Western Australia. The population is about 15,000 animals, with 80 percent of sea lions located in South Australia. In South Australia, there are 39 breeding colonies, but most are very small and some of these are at risk of becoming extinct because each breeding colony is a closed population. Large colonies exist at Dangerous Reef in the Spencer Gulf, Seal Bay on Kangaroo Island and The Pages. There are smaller colonies on the West Coast and in the Great Australian Bight.

They do not require to be kept cool and wet as do stranded whales and dolphins. Species such as leopard and elephant seals can be comfortable around people and are almost always just onshore to rest, however fur seals and sea lions that are hauled out in public places are sometimes in poor condition. The most appropriate management for seals is simply to isolate them from people and leave them undisturbed to rest. This can also be important to ensure public safety. The information proposed below, can then be collected, starting with the species identification as this will usually give the first clue as to the likely predicament of the animal. If a seal is found on a beach, please undertake these two steps before any other action is taken: 1 Observe the seal and note the important information to report below; 2 Ring DPIPWE Wildlife Management Branch on the 24-hour hotline number 0427 942 537 for further advice ACTION FLOW CHART 1 Locate Observe and Record - 2 from 10m or more, see datasheet Ring Hotline - 0427 942 537 3 If in public area such as car park, road, built up area move to step 6 4 Isolate Fencing and signage Let Rest 5 Most seals are ashore to rest and leave on next tide Intervention 6 Only for welfare reasons or public safety Please ring DPIPWE Wildlife Management Branch 0427 942 537 for further advice 3 SEAL ONSHORE – INFORMATION TO REPORT: PLEASE FILL IN THE FORM BELOW The following information will be vital to staff when evaluating the seal onshore situation.

  • Molecular Ecology of Marine Mammals
    Molecular ecology of marine mammals Morten Tange Olsen Department of Genetics, Microbiology and Toxicology PhD thesis Spring term 2012 Supervisors: Per J. Palsbøll and Martine Bérubé © Morten Tange Olsen, Stockholm, Sweden, 2012 ISBN 978-91-7447-403-9 Printed in Sweden by US-AB, Stockholm, 2012 Distributor: Department of Genetics, Microbiology and Toxicology, Stockholm University, Sweden ii Abstract Marine mammals comprise a paraphyletic group of species whose current abundance and distribution has been greatly shaped by past climate fluctuations and anthropogenic impacts. This thesis describes molecular ecological approaches to answer questions regarding habitat requirements, genetic differentiation, and life-history trade-offs in three species of marine mammals. The annual sea-ice dynamics of the Arctic may have large effects on the abundance and distribution of Arctic species such as the pagophilic ringed seal (Pusa hispida). Paper I describes and applies a simple molecular method for isolating and characterizing a relatively large set of single nucleotide polymorphisms (SNPs) in the ringed seal. These SNPs have been genotyped in a yet-to-be-analysed dataset which will form the basis in an assessment of the micro-evolutionary effects of annual sea-ice dynamics on ringed seal. Current management efforts directed towards the North Atlantic fin whale (Balaenoptera physalus) are hampered by an unclear understanding of population structure. Paper II investigates the DNA basis for the high levels of genetic differentiation that have been reported in allozyme studies of the North Atlantic fin whale. We find that additional processes (at the organismal level) may have contributed to shaping the phenotype of the underlying allozyme variation.
