| phylum | Chordata | Odontaster validus is a species of starfish in the family Odontasteridae. Its range includes the Southern Ocean and the seas around the mainland and islands of Antarctica. Odontaster validus can grow to about 10 cm (4 in) in diameter. The disc is broad, thick and cushion-like, creased by interambulacral grooves. There is a large madreporite near the centre and the surface is covered in small granulations organised in radial rows. The five short arms are wide at the base tapering sharply and the tip is often raised off the substrate showing the pale coloured tube feet beneath. The colour of the upper or aboral surface is plain red while the underside is pink.
