 Description:
Well-preserved examples of a member of the Asteroidea, or True
Sea Stars. While it looks more like a brittlestar due to the slender
arms, members of  the family Echiasteridae are known by the common
term slender-armed sea stars. There are some fifty extant species
that make their living filtering out phytoplankton. The site has
been closed to collecting for some time now, so specimens like
this will be harder to replace. There is one repaired crack which
was done when it was collected in the field. The species derives
its name from the site where the specimens were found. |
