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.
There are two sub-types of sea stars: Asteroideas are the true sea stars and sun stars. Ophiuroideas are brittle stars and basket stars. The differences between the two sub-types lies in how the arms connect to the central disk. Ophiuroids have arms that do not connect with each other. There is a distinct boundary between arm and central disk.
