A team
of engineers and marine biologists from the University of California have devised
a tool, taking inspiration from sea urchins’ (Strongylocentrotus fragilis)
intricate mouth and teeth, to sample sediments on other planets. The device was attached to a
remote-controlled small rover and used to claw on sand that simulates Martian
soil in density and humidity. It is worth mentioning here that a colony of sea
urchins can destroy an entire kelp forest by churning through rock and
uprooting seaweed.
Details
appear in the latest issue of the Journal of Visualized Experiments.
