George (2004) found that, when compared to controls, subjects with DPN exhibited significantly lower walking velocity, and cadence, as well as impaired reaction time and ability to produce rhythmic limb acceleration (9).
Brittle stars are a moderately popular invertebrate in fishkeeping. They can easily thrive in marine tanks; in fact, the micro brittle star is a common hitchhiker that will propagate and become common in almost any saltwater tank, if one happens to come along on some live rock.
Natural History. Brittle stars live on spiny sponges and other sessile animals in massive fields on the muddy seafloor, as well as by themselves or in abundance directly on the seafloor.
