Teckarck eggs are extremely difficult to spot because, well, they look exactly like a giant leaf in the jungle.
Teckarcks are the alpha rat of the western jungles of Ark, off the coast of the Ark River. Sometimes they can be found as far northwest as Leila but oftentimes they just stay in the jungle.
Teckarcks absorb most of their nutrients and life energy from the moisture found in plants on the jungle floor. Unfortunately, this is a one-way transaction whereby the plants are completely depleted of their moisture and thus die. The Teckarck population, for this reason, is very strictly controlled by the government in Ark City to protect the western jungle.
Teckarcks are technically classified as a pest.
