The teeth of sea lions are categorized as heterodont, meaning they have different types of teeth that serve specific purposes. Towards the front of the jaw, sea lions have sharp incisors that help them grip onto prey. This is followed by elongated canine teeth that are used for puncturing and holding onto their catch. Further back in the jaw, sea lions have premolars and molars with flattened surfaces that allow them to crush and grind the food.

The jaw joint of sea lions also plays a crucial role in their feeding adaptations. They have a mobile joint that allows for a wide range of movement, enabling the jaw to open wide to catch and swallow large prey. Additionally, the jaw joint is well-muscled, providing the necessary strength and power to exert force during biting and tearing.

Sea lions rely on their jaw and teeth structure to hunt and consume a variety of prey, including fish, squid, and sometimes even small seals. This adaptation enables them to efficiently capture and process their food, ensuring their survival in their marine environment.
