Sadly, most of the "Tenae" race is oversized, to the point where Tenae's are often indistinguishable, not just between male and female, but between a planet and a Tenae. It is predicted that by 2013 the International Union d'Aerospatiale will have catalogued and assigned codes to all the Tenae's on our planet, declaring them planets.
It should not be forgotten also, that many Tenae's have a particular affinity for blood, and are known to be more than rough in the bedroom, which they also spend alot of time in.
Other than these things, Tenae's are known to be fun, carefree and over the top, but in a good way (most of the time). Their natural habitat is the beach, doing sporty things (ironic considering their planetary size), whilst they particularly despise all forms of chemistry, except organic chem. Often they are quick to argue and jump at a sarcastic remark, and often they are left without any sort of response, their mouths gaping whilst they are dominated by superior beings such as Jason's and Nic's. It is believed by many animal experts that this "gaping mouth" explains both the sexual reactivity of a Tenae and their size, however it is not known for sure.
