Sea Dragon

Created on Day 5


The sea dragon has an interesting design. It lacks a caudal fin, and has bony plates covering its body. These characteristics restrict its mobility, but the bony plates provide great protection from possible predators. Because of this protection as well as its great camouflage, the sea dragon does not have many predators.


  • The sea dragon has elaborate skin filaments that hang from its head, body, and tail.
  • The appendages of the leafy sea dragon are usually a shade of green or yellow, and the appendages of the weedy sea dragon are purple with a black border.

Fun Facts

  • To eat, this creature sucks plankton and tiny crustaceans into its tube-like snout.
