The pygmy seahorse is one of the ocean's most remarkable masters of camouflage and a bucket-list sighting for macro enthusiasts visiting Komodo. At barely 2 centimetres in length, this tiny fish is virtually indistinguishable from the gorgonian sea fan on which it spends its entire adult life. Its body is covered in rounded tubercles that perfectly mimic the polyps of its host fan coral, matching in both colour and texture. There are two main colour forms — pink with red tubercles on Muricella plectana fans, and yellow with orange tubercles on Muricella paraplectana. Pygmy seahorses were only discovered in 1969 when a scientist noticed them on a sea fan being examined in a laboratory, and they remained virtually unknown to divers until underwater macro photography advanced enough to capture them. In Komodo, experienced dive guides know the locations of specific sea fans that host resident pygmy seahorses, and they are a highlight of dives at sites with large gorgonian gardens.

Feeds on tiny crustaceans and zooplankton that drift past its sea fan host. Uses a sit-and-wait strategy, sucking in minuscule prey with its tubular snout as they pass within range.
