Color In Nature: Leafy & Weedy Seadragons

April 29 2009, 12:31pm

As mystical as the legendary creature that shares its name, the sea dragon is a cryptic marine fish that uses color and weed-like appendages to camouflage itself. There are two types of sea dragons, which are related to the seahorse: leafy and weedy. These creatures are found around southern and western Australia. Leafies are generally brown to yellow in body color with spectacular olive-tinted appendages. Weedies have less flamboyant projections and are usually reddish in color with yellow spots.

These small fins are almost completely transparent and difficult to see as they undulate minutely to move the creature sedately through the water, completing the illusion of floating seaweed.

Sea dragons, sea horses and pipe fish are the only species where the male carries the eggs.

This is obviously not a real sea dragon but it's still a nice image, from Lush.i.ous. Text adapted from Wikipedia: 1, 2 & National Geographic.
