South American sea lions (Otaria flavescens), also known as southern sea lions, are also called sea lions (Otaria byronia). These are seal-like marine animals who can swim in the water and stay on land. They range in size within the species and between males and females, adults have dark-brownish backs and light brown chests. The manes on males are more moderate than females, and females’ fur seals on their heads and necks are lighter than that of males. Males have massive heads and necks with characteristically extended noses. South American sea lions live for about 20 years. These marine animals rarely walk far from the coast, relatively talking.

In coastal areas, they tend to group in large herds, on rocky outcroppings. The astounding creature also carries mating practices and nesting practices in the same general region. The beautiful powerful animals also evolved as fully hungry carnivores and possess the same habits and patterns as their relatives. They also maintain a moderately broad diet but show a strong choice for a species of fish. They also feed on other species, though normally opportunistically. This other prey mainly involves small cephalopods, such as squids and octopuses. Occasionally, they have been seen feeding on young South American fur seals and sea birds such as penguins and pelicans. The population of these marine animal is stable as of now which is why they are listed under Least Concern.

What is a South American sea lion's habitat?

The South American sea lion is seen from northern Peru as far south as Cape Horn. When at sea, most of them prefer coastal waters, with adult males differing most faraway. Many breeding colonies are on Falkland Islands, Brazil, Uruguay, Argentina, and other regions with limited human disturbance, and sandy beaches are more often used than solid beaches. They prefer ocean shores for habitat, especially during mating season.

Who do South American sea lions live with?

South American sea lions are a regular and social species that live in groups usually consisting of multiple females with one or several males who defend their colonies.

How long does a South American sea lion live?

South American sea lions have a lifespan of about 20 years.

How do they reproduce?

In biological environments, successful mating follows in males, as young as two years. In the wild, social factors greatly affect males breeding success. Males may not successfully reproduce until about nine years of age when they achieve the full size and can compete for females. For these southern sea lions, the breeding season starts from August to December. The male South American sea lion is very proactive when it comes to herding females into their zenanas. Most of these females will already be pregnant from the last breeding season. Soon after giving birth, fur seals will mate. Males with no harem of their own may band into groups and try to take over mating with adult females. They are also known to kill the pups in the group due to feeling threatened by them.

In the past, it seemed that all of the matings took place on the sandy beaches. However, experts know now that they can also mate on the hard mountains in their habitat. Adult females will nurse their young pups for about a year because they need to get ready for the birth of the next one. Pups stay on land until they are about a month old. Many of them expire due to the mothers having to go into the water to get their food. Once reaching a maturation period of 11 months, the southern sea lion gives birth to a single pup. They are detached at 6-12 months old. Male pups are known to mature later than female pups, as they generally reach maturity at six years of age, whereas female pups are mature at four years of age. Both reproductions reach their full adult size at around eight years of age. Depending on the size of the population, the death of a pup generally ranges from two to 50%. Higher pup deaths have been observed because of the greater risk of pups being crushed to death by adult sea lions. Pup deaths also occur due to starvation (when they lose their mother), predators, diseases, and drowning. Pups spend their time, staying in groups, playing, sleeping, or residing near the water. Unless guided by their mothers, they rarely swim in deeper waters. At about three to four weeks of age, they generally swim underwater, with other sea lions in a large group.

What is their conservation status?

The conservation status of South American sea lions are of Least Concern since their population is stable for now. In certain regions, some of the species of this animal are under threat or have gone nearly extinct.
