2009 Coral Morphologic

Here a 2 centimeter Periclemenes pedersoni shrimp is seen perched on its host colony of fluorescent orange Ricordea florida corallimorphs. Pederson’s shrimp are native to Floridian and Caribbean waters, and are found in symbiotic association with a variety of sea anemone and corallimorph species. Pederson’s shrimp live amongst the tentacles of these animals, immune from their sting. They act as ‘cleaners’ of much larger fish. The shrimp wave their antennae and swim in a characteristic swaying motion to signal that they are ‘open for business’. Fish seem to learn and remember the specific location of these ‘cleaning stations’, returning as needed for service. When not removing parasites from fish, these shrimp will forage for bits of food amongst its host’s tentacles and spend time preening itself, as can be observed in the video. Pederson’s shrimp form monogamous mated pairs that will live together on same host. These shrimp are quite territorial, fighting fiercely with its own kind if another Pederson’s shrimp tries to take up residence on its anemone or corallimorph. If an ‘unmated’ shrimp tries to take up residence too close to an established territory, the invader will usually be dissuaded through threat displays and physical harassment.

Pederson’s shrimp are closely related to the spotted cleaner shrimp (Periclimenes yucatanicus) featured last month.

During the nights of Art Basel Miami Beach our 2009 film reel was displayed on the 80′ X 42′ LED screen on the facade of the American Airlines Arena in downtown Miami as part of the Media Mesh Project. The video compilation was curated by artist George Sanchez-Calderon and featured short films by the following artists: Lou Ann Colodny, Aiden Dillard, Alvaro Ilizarbe (Freegums), Justin Long, Ferran Martin, Coral Morphologic, Gavin Perry, Carlos Rigau, Bert Rodriguez, Damian Rojo, TM Sisters, and Jen Stark.

During the night of Saturday, December 5th we displayed a video projection at the Art Basel Miami Beach satellite Moksha Art Fair. The subject of the the film was an Entacmea quadricolor sea anemone (right) and its corresponding reflection (left).

Pictured above and below is ‘Version Key’ as installed at the Miami’s Independent Thinkers art show during the days of Art Basel Miami Beach. The aquarium consisted of an eroded cinder block, red mangrove (Rhizophora mangle) seedling, and three upside-down jellyfish (Cassiopea xamachana) pulsating on oolitic sand; not an atypical South Floridian assemblage. It was displayed against a silver parachute backdrop on a concrete block pedestal surrounded by oolitic sand.
