Editing Trill (section)

==Physiology==

The Trill are distinguished by two rows of spots going down each side of their body, from head to toe. One of the main neurotransmitters in the Trill brain is isoboromine. Joined Trill are also extremely allergic to insect bites; the biochemical connections between the host and symbiont can not tolerate the reaction caused by the insect's venom. One Trill peculiarity is that they are known for having cold hands. 

The few Trill that are given a symbiont are typically joined in their early to mid-twenties. The physical process of being joined is irreversible. Once joined, the host and symbiont are dependant on each other. If the symbiont is removed the host will die, even if they are otherwise healthy. The symbiont will die within hours if not transplanted to another host.
