Unlike their Echinoderm brethren, brittle stars do not move along on tube feet that can propel them in any direction. Instead, brittle stars ‘walk’. This mode of movement by brittle stars is even more astonishing when it is considered that brittle stars, like all echinoderms, are not bilaterally symmetrical, i.e mirror imaged halves.

Daniel D. Brown, LaughingMantis.com. Echinoderms are one of the most highly derived groups of animals with many species as significant components of several marine communities. They’re classified by three fundamental shared characteristics: 1) pentaradial symmetry, 2) skeleton made of three-dimensional calcitic elements, and 3) the presence of a water . . . → Read More: Veins of Water: The Evolution of the Echinoderm Water-Vascular System

Where do we come from? Where are we going? Are we alone in the universe? The answers to these thrust at the core of our humanity and uniqueness. Through science we seek out replies to these inquiries.
