Sandsharks are a dragon in the How to Train Your Dragon book series, first described in book 12. They are aligned to the Dragon Rebellion, but are considered to be one of the less fearsome rebel dragons.
Because of its aquatic like appearance and ability to 'swim' through the beach sands, the Sandshark might be classified as a type of Sea Dragon.
Traits and Abilities
Sandsharks are around the size of a wolf or large dog, and hunt in packs like them. They are called Sandsharks because of the sail on the tops of their heads that greatly resemble a shark's dorsal fin. They are able to 'swim' through sand like water, with only their head sails showing.
These pack hunters shoot poisoned darts at their targets, by lifting their heads from the sand just long enough to fire, then duck back under the surface. The darts are poisonous, but usually only bring about unconsciousness, rather than death. The larger the prey, the more darts are required to bring it down. The subdued prey then put up no resistance as the Sandsharks rapidly devour it.
