The Australian Sea Lion is one of the most endangered breed of sea lions in the world with an estimated decline of 60% of their population. The females are at least 6 – 10 years of age before they breed which is approximately once every 18 months. The females never leaving their bird site colony. Individual colonies breeding schedules can occur across different seasons any time of the year. They are particularly sensitive to disturbances. After the lion pups no longer require their mother’s milk, the mother spends another 18 months teaching the pup to catch their own food such as fish, crabs, squid etc.
