The difference between a sea lion and a seal is that the former had has flaps over its ears and large front flippers that allow it to maneuver around on land more easily. Seals and sea lions have many similarities with land carnivores like dogs and cats such as a long snout and sharp teeth and are thought to have developed from land mammals about 20 million to 25 million years ago. There are 34 species of seal, all of which mate and give birth on land and feed at sea.
There are records of Otaria flavescens inhabiting the Galapagos and Falkland Islands. South American sea lions reside along shorelines and beaches. They also inhabit flat rocky shelves or cliffs with tidepools and boulders.

Sea lions are 7 species of large marine mammals in the pinniped seal family. The sea lions ancient ancestors were land animals somewhat similar to bears.

Behavioral Ecology and Sociobiology. Proximal mechanisms underlying a faster growth rate in male compared to female California sea lion pups were investigated. Males are significantly larger at birth than females. Specifically, we asked if differential maternal investment contributed to enhanced male growth via: 1 larger mothers having disproportionately more male pups, 2 more time and energy put into foraging by mothers of male pups, and 3 greater milk production in mothers of male pups.
