Seahorses rely on camouflage as their primary form of survival.  As if sea horses weren’t hard enough to find already, there is a type of seahorse called a “dwarf seahorse”.  To find these, you need a sharp eye, patience, and luck.  This photo is a dwarf seahorse that is about the size of my thumbnail.  Besides being exceptionally small, they are also very slow moving.  In fact, the Guinness World Records says the dwarf seahorse is the “slowest-moving fish”.  Top speeds max out at about five feet per hour.  Like some other fish, seahorses have cirri (small skin growths that look like algae) that help them camouflage.
