### Identification The Arborescent Clinid is a master of disguise, reaching a maximum length of about 18 cm. Its elongated, tapering body is typically a mottled tapestry of mossy greens, rust-reds, and sandy browns—perfectly mimicking the kelp forests it calls home. The definitive field mark, however, is the magnificent pair of orbital cirri. These are not merely bumps but elaborate, branching, "tree-like" tentacles sprouting above each eye (giving the species its name). To distinguish it from the similar Super Klipfish, look for these bushy tufts and a dorsal fin that begins slightly further back, lacking the prominent "peak" at the front.
### Habitat & Range This species is a South African endemic, found almost exclusively in the cool, nutrient-rich waters of the Western Cape, ranging from False Bay to Still Bay. You won’t find them in the open ocean; they are specialists of the intertidal zone and shallow sub-tidal reefs. They tuck themselves into deep rock pools and crevices heavily draped in seaweeds and bryozoans, rarely venturing deeper than 10 meters.
### Behaviour A patient lurker, the Arborescent Clinid spends its day wedged into rocky fissures, using its stout pectoral fins to "prop" itself up or crawl along the substrate. They are highly territorial and sedentary, often staying in the same small patch of reef for life. Most remarkably, they are viviparous; unlike most fish that scatter eggs, the female gives birth to fully-formed, free-swimming young, providing them a significant head start in the turbulent surf.
### Diet As an ambush predator, it remains motionless until a meal drifts within reach. Its diet consists primarily of small benthic invertebrates, including amphipods, isopods, and tiny crabs. With a lightning-fast strike, it creates a vacuum to suck prey into its small but capable mouth.
### Fascinating Fact The "trees" on its head aren't just for camouflage; they are highly sensitive tactile organs. In the surge of the Cape coastline, these cirri help the fish "feel" the movement of the water and the presence of nearby prey, even when the visibility is churned to a murky soup!
