Gizzork

The Gizzork are space borne creatures who are capable of surviving in the vacuum of space for long periods of time, if not indefinitely. They have a very complicated language of hand signals mixed with alternating lights from their antennae. Strangely the name "Gizzork" is a common name used by all members of the species, and each individual Gizzork cannot understand why members of other species cannot tell them apart from each other.
