Exciting news from the world of mollusk research! Scientists have discovered new insights into how cuttlefish blend in so seamlessly with their underwater world.  Cuttlefish are chameleons of the undersea realm: they have the ability to change their color and texture in order to blend in with seaweed, coral, the ocean floor or whatever habitat they encounter.  Yet, even more remarkably, they can mimic the rough coloration and shape of other organisms, thereby fooling predators and prey by mimicking crabs and fish.

Cuttlefish copy the textures they find in their environment by means of small nodules known as papillae.  The cephalopods extend and retract these intricate bumps using muscles. They can become perfectly smooth in order to maximize their speed and maneuverability or they can take on the texture of rocks, coral, or even seaweed.  Scientists have discovered that the cuttlefish accomplishes this not by means of continuous concentration, but instead with muscles which can be locked in place by means of certain neurotransmitters (it pays not to contemplate the vivisection through which this knowledge was obtained).  If a cuttlefish takes on a certain texture and then promptly loses use of the relevant muscle nerve, the neurotransmitters remain active and it takes hours for the creature’s metabolism to return it to its neutral shape.

This may seem like a minor insight, but learning that cuttlefish (and presumably the squids and octopuses which use the same sort of papillae to alter their texture) are utilizing a muscle trick which is not unlike mechanism by which clams lock their shells in place is another step in unlocking the mysteries of these remarkable tentacled masters of disguise.

Maria Tomasula is a contemporary artist who paints strange collections of beautiful items coalescing into miniature glowing geometric systems (usually against an empty black outer space backdrop).  Dew, flowers, and fruit are the most frequent items in these compositions, but sculptures, amphibians, skulls, mollusks, weapons, and disembodied organs (among other things) also find their way into these little microcosms.

Tomasula paints the shining or dewy objects which make up her still life works with finicky photorealism, yet the abstract structure of the works takes these images towards mathematical abstraction. Her delightful little paintings give us the aesthetics of the natural world as viewed through a dark melting kaleidoscope.

Tomasula has a particular flair for teasing humankind’s magpie-like fascination with shininess and bright colors.  From across the gallery, her works beguile the viewer closer and closer.  Only when one is next to them does one notice the carnivorous pitcher plants and bird skulls among the velvet, petals, and jewels.   However the dark imagery does not outshine the sensuous appeal of these fastidious spirals, loops, and curtains.  Tomasula invites us to reach into the dark fractal pattern of beauty to grab the waxy flowers, the moist fruits, the polished gems…if we dare.
