This female specimen of a Xyloplax seastar was collected along the Juan de Fuca Ridge off the coast of the state of Washington; it measures less than a quarter-inch (4 mm) and shows brooded embryos Some of us never grow up.

Heightened biodiversity may make an ecosystem more stabile and robust. One of the reasons for this is that high biodiversity may create redundant species, i.e. species that serve a similar ecological role in the ecosystem.
