Male sea lions grow to twice the size of females. They can grow up to 200-250cm long
and can weigh 250-300kg. They have dark brown fur with long, yellow course hairs grown on the top of the head and around the
neck, almost like a mane.
Females have a silvery grey to fawn colour on the back, with a creamy yellow colour
on the belly. They grow to 130-180cm long and weigh between 70 to 100kg.
When born, pups are chocolate brown and after their first moulting phase their fur
is the same colour as the females except with a pale fawn crown on their heads. They weigh 6.7-7.9 kg and are 62-68cm long.
