Ejector suncus

A member of an Alien fauna on a fictional Earth-like Planet called Snaiad.
The creature's description on the website:
"Dotting the endless lush plains of Pansavannah like bright green melons, these conspicuous terrestrial Turtiformes are given a wide berth by most predators. These animals spend most of their lives calmly wandering around the plains while their disturbingly hyperactive second heads constantly pluck small animals and nutritious plants from the earth. Should they be attacked, they “vomit” an extremely potent irritant from their striped first heads with uncanny precision. This substance, actually a modified form of genital lubricant, is always aimed at the attackers’ eyes and has been observed blinding or even killing young and inexperienced predators.

With the equally toxic (but unrelated) Turtletanks (Hoploderma sp.) and poisonous Bandia Lophophids inhabiting the same region, Snaiadi zoologists have been paying special attention to the Pansavannah region, trying to figure out why so many slow but well-armed herbivores have been concentrated in this area. One popular theory is based on the historical presence of unknown, vicious predators in the region, but no fossil discoveries supporting this claim have emerged. The current assemblage of predators inhabiting Pansavannah is not much different from those elsewhere on the mainland continents."
