A species of brittle sea star sprawls, indolent on a sun-bathed rock, one arm testing a crevice it can secret itself in. It spreads itself, comfortable in its long limbs that name them also serpent stars. They are quick and flexible; we find them hiding under rocks, jammed in impossible small cracks. They are slender surprises as we roam, spotted from an arm snaking out from a small gap, pushed slightly by the water as if it were no more than a piece of seaweed, an unusual glint of light off their body. They form cryptic, but welcome, surprises.
