We were recently commissioned to create the official video for the London/ Paris based electronic music collaboration WALLS, released by Kompakt Records in Berlin. ‘Hang Four’ was premiered on NME.com.

The yellow coral in the opening and closing shots is a sun coral (Tubastrea coccinae). The polyps are seen expanding in reaction to the addition of food to the aquarium. Unlike most reef building corals, the sun coral is non-photosynthetic, and relies on the capture of plankton as its sole energy source. In the Gulf of Mexico and Florida, this is an invasive coral species that most likely hitched a ride into the Caribbean basin following the opening of the Panama Canal. It has since spread northward into the Gulf of Mexico, colonizing oil rigs one-by-one. This particular colony was collected from one of the rigs not far from the BP Deep Horizon disaster about 2 years ago. It is unknown to us whether these corals have been negatively impacted from the spill, but as an invasive species, it raises a number of questions about whether their potential loss should be considered a detriment or not. Nevertheless, research on the impact these sun coral communities have experienced in the Gulf will be useful in determining oil tolerance on a stony coral species in close proximity to the oil disaster.

The iridescent, twinkling gelatinous creatures are called ctenophores (TEEN-o-fores) (aka comb jellies) ranging in size from 5-10mm in total length. They float in the open ocean and beat their rows of cilia (the iridescent, beating ‘combs’) which allows them to filter plankton out of the water. They often float in huge conglomerations of hundreds of thousands. They are an important part of the pelagic (open ocean) community of plankton likely impacted by the oil spill in the Gulf.

The little jellyfish are called ‘club hydromedusa’ (Orchistoma pileus) and range in size from 7-10mm. They also live in the open water near the surface, using their stinging tentacles to capture smaller zooplankton.

Morphologic friend and colleague Akihiro Shiroza recently returned from a stint at sea aboard a NOAA research vessel. He spent several weeks floating amidst the oil slick in the Gulf of Mexico studying the effects of the spill on the pelagic plankton community. As an accomplished artist and videographer, NOAA asked Aki to formally document their work on video. This allowed him unprecedented access to capture film of the rainbow-hued sheen of oil that coats the surface of the Gulf. ‘Resonance of Contrary Components’ is at once disconcerting and sublime.

The Squat Urchin Shrimp (Gnathophylloides mineri) is an amazingly successful creature that can be found living amongst the spines of sea urchins throughout most of the world’s shallow tropical waters. In the Caribbean they hitchhike exclusively upon the black and white West Indian Sea Egg (Tripneustes ventricosus), traveling along where ever its host may go. The squat urchin shrimp is very small, reaching no more than 6mm in length, and orients itself parallel with the spines making it all but invisible and protected from a would-be-predator. Often colonies of up to half a dozen squat urchin shrimp of varying sizes will all share the same urchin. Beyond its circumtropical distribution and perfect camouflage, the squat urchin shrimp further demonstrates its successfulness by feeding upon the epidermal tissue of the very spines that grant it protection. This is a relatively benign form of parasitism that doesn’t seem to bother the urchin. These shrimp will also feed opportunistically upon detritus that the urchin picks up as it moves along the sea floor. The squat urchin shrimp is a creature that has found a near perfect niche in a truly self-sustaining, self-contained world of spines.

‘Cleaner’ Pt. 3

The sun anemone shrimp (Periclimenes rathbunae) is the least common of the three species of Floridian anemone shrimp. While the other two anemone shrimp (P. pedersoni and P. yucatanicus) act as cleaners to passing fish, the sun anemone shrimp doesn’t seem to engage in this behavior. Instead, it spends its time living almost exclusively upon its namesake sun anemone (Stichodactyla helianthus). Aquarium observations suggest that this shrimp may supplement its diet by occasionally nipping off and eating the tentacles of the anemone. This parasitism suggests a more complicated symbiotic relationship than the sort of simple mutualism that these shrimp are often categorized by.

In Floridian waters, the scarcity of this shrimp is likely related to the infrequency of its host sun anemone. However, where they are found, the sun anemone often lives in dense clonal colonies that can literally carpet shallow reefs. The tentacles, while short and stubby, are packed with powerful stinging nematocysts that act like microscopic harpoons to deliver their venom. The end result of all these nematocysts and tentacles, is an anemone that is very ‘sticky’, and capable of producing painful welts to the careless diver.

The tiger flatworm (Pseudoceros crozieri) is a stunning species of flatworm that can be found living on rocks and mangrove roots along the shores of the Caribbean. Colonial orange tunicates (Ecteinascidia turbinata) constitute the tiger flatworm’s only food-source. At 35mm in length, it is considerably larger than the previously featured red flatworms. As simultaneous hermaphrodites, the tiger flatworm often travels as pairs and mate regularly. Their pseudotentacle antennae help aid them in finding mates by detecting chemical cues in the water.

Locomotion in this larger flatworm species is accomplished by rippling muscle contractions along the edges of the animal, and aided by a slippery mucous slime. The video is shown in real time.

‘Flatworms’

The flatworms (Convolutriloba retrogemma) featured in the video are shown at 3x normal speed. They each range from 2-4mm in total length.

These particular flatworms harbor symbiotic zooxanthellae in their thin tissue and utilize the excess sugars they create as their primary energy source. Packets of zooxanthellae can be seen as the tiny, red-brown dots along the back of flatworm. Their reliance upon this photosynthesis requires that these flatworms bask in sunlight like little photovoltaic cells, and enables them to live without a developed digestive system.

In the wild, this species can be found in the shallow water of protected lagoons and around mangroves. Reproduction is accomplished asexually via fission, in which the flatworms literally split into two. This strategy enables exponential population growth in optimum conditions. They are the preferred prey of several species of larger flatworms and sea slugs; animals that can tolerate their toxic bodily fluids.

While it appears that the flatworms just glide along like magic carpets, they are actually propelled by invisible cilia (flapping filaments) that slide them across a thin layer of mucous laid over whatever surface they happen to be upon.

Upon close inspection of flatworm-to-flatworm interaction, it is apparent that these flatworms do not like making direct contact with each other. If they do, they react as if stung. It seems that this reaction prevents the worms from piling on top of each other in an effort to gain the best solar power. Instead, they jockey for position until they each find a place in which to ‘park’ themselves, like sunbathers on a crowded beach.

On Saturday April 17th, we projected two video loops during ‘Sweatstock’; a free, all-day, all-ages block party in Miami’s Little Haiti neighborhood celebrating Sweat Records 5-year anniversary.  For No Age (Sub Pop), Sweatstock’s headliner, we projected the neon green mouth of a Fungia sp. coral that actively ‘smiled’ over the energetic performance and enthusiastic audience, as seen in the video above.

Prior to No Age, we displayed an undulating, double-mouthed Ricordea florida polyp for Otto von Schirach‘s swamp-freak take on Miami Bass electronica (below).

We are proud to have helped contribute to what we consider was the best music festival Miami has seen in recent memory. Congrats and thanks to Lolo and Sweat Records for an awesome 5 years of organizing and promoting our Miami music scene; the Magic City would be a lot less magical without your hard work and drive.
