Seals are marine animals only mentioned in the DreamWorks Dragons franchise.
Their hearing and eyesight are adapted for both water and air. In addition, they developed advanced tactile system in their whiskers.
Their diet mostly consists of fish marine invertebrates, although some species (like the leopard seal) eat larger animals.
In the franchise, the seals have no function.
In reality, seals are hunted for their pup's fur, though it is illegal in most countries.

In the episode, "A Gruff Separation", the Twins compete against each other for the Thorston Initiation Trials. Each is doing it for the benefit of the other, but unbeknownst to them. Gruffnut tries to talk Ruffnut by telling her she might become an old maid, or "a baby seal named Derriq, with a Q".
According to Dreamworks' Youtube Video Series, "The DreamWorks Download", Toothless, and perhaps the Night Fury as a species, was inspired by many animals, including elephant seals. "The noises Toothless makes are a combination of elephant seals, elephants, tigers, horses, and domestic cats."
