Dewgong is a sea lion Pokémon. Its body is extremely streamlined, allowing it to swim up to 8 knots. Its fins and tail are larger, stronger, more fish-like, and more developed than its pre-evolution's. Its long tail is able to change swimming direction quickly when needed. It is covered in pure white coat of fur that obscures it from the view of predators when in the snow. It also has a layer of thick fat, that allows it to store thermal energy and protects it from intensely cold water and air. Dewgong also has a small black nose, and fangs or small tusks protruding out of its upper jaw.
