A paxilla (plural. paxillae) is a small umbrella-shaped structure sometimes found on Echinoderms, particularly in starfish (class Asteroidea) such as Luidia, Astropecten and Goniaster that immerse themselves in sediment. They are ossicles composed of calcite microcrystals found on the aboral (upper) surface of the animal. Their stalks emerge from the body wall and their umbrella-like crowns, each fringed with short spines, meet edge-to-edge forming a protective external false skin. The water-filled cavity beneath contains the madreporite and delicate gill structures known as papullae.

dbo:abstract
  • Una paxil·la és una petita estructura en forma de paraigües que de vegades es troba en els equinoderms, particularment en les estrelles de mar (classe Asteroïdeus) com Luidia, i que se submergeixen en els sediments. Són ossicles compostos per microcristalls de calcita que es troben a la superfície aboral (superior) de l'animal. Les seves tiges surten de la paret del cos i les seves corones semblants a un paraigües, cadascuna de franges curtes, es troben de punta a punta formant una falsa pell externa protectora. La cavitat plena d'aigua que hi ha a sota conté la placa madrepòrica i delicades estructures branquials conegudes com a papil·les. (ca)
