Sea dragon that evolved to prey on small cetaceans. It locks its wings like an albatross and glides over the ocean for weeks, even months at a time. Its fire-breathing organs have adapted to become highly efficient gas bladders that help it maintain lift without expending energy. When it sees the spouts of a pod surfacing for air, it begins to circle. If a calf strays too far, the sea dragon strikes like a falcon. The calf is usually killed or paralyzed on impact. The sea dragon can then swim to the surface and safely carry its prey back to its nest.
Hunting the young of larger cetaceans can be risky. If the sea dragon strikes when the calf is still too close to its pod, the rest of the pod may be able to get above the submerged predator. The adults will proceed to push the dragon deeper underwater. Unable to surface, the dragon will drown.
Sea dragons nest on the cliffed coasts of volcanic islands. They are extremely territorial and aggressive towards other members of their own kind, and have even exhibited opportunistic cannibalism. There have been no documented sightings of sea dragons mating — they are widely believed to be parthenogenetic.
Sea dragons are around 15m (~50ft) long, with an approximately 35m (~115ft) wingspan.
