Eeeeh works for me.

Sea lions, much like regular lions, are typical animals nobility chooses to represent them due to their strength and ferocity. Though they don’t seem much different from beasts as far as intelligence goes, they’re actually classified as monstrosities (thus spells like Beast Speak doesn’t work on them). While individually dangerous, wild sea lions are deadly effective pack predators and can often be found roaming in packs of 3-6 to hunt down large prey. Finally it is said that sea lion claws can be used to create water breathing potions and their manes are highly effective to keep one-self protected from cold weather and effects especially in the see ocean.
