I desire, with all of my heart, to see a mollusc I have never seen before
The Spanish dancer (Hexabranchus sanguineus) is a large nudibranch that inhabits tropical and subtropical waters in the Indo-Pacific region. Unlike most nudibranchs, it is capable of free-swimming, using undulations of the wide, flattened edges of its mantle to propel itself through the water. The whirling motion as it swims is reminiscent of the skirt movements of a flamenco dancer, hence its common name.
