Canis insectomorfus

CANIS INSECTOMORFUS (dog insect-shaped) is an apex predator of its territory. It is a socially complex animal who lives in groups with a very rigid hierarchy. Two of the trunks are in fact sensorial and mainly social organs used to communicate with their peers. This creature preys usually on creatures bigger than itself. It's highly intelligent and uses complex hunting strategies to hunt the prey down. The third trunk also corresponds to the mouth and has a dentate pincher on its extremity. This trunk can be elongated to arpoon on preys while running fast to injure them and slow them down. The first pair of legs is used as a cleaning tool for the respiratory orifices, to anchor on preys, and to lacerate the meat that has to be eaten in chunks because the creature doesn't have any chewing apparatus. The other two pair of legs are used as a locomotion apparati and the last one over time assumed the function of a tail to maintain equilibrium.

Three more creatures complete a single and simple biome's food chain that exist in the vast northern plains.

So the first one is a plant (VILEPLUMICUS MAGNUS, The Big Vileplum) originated from Sidobosia. since it needs a very big amount of surface to get the energy necessary to move the petals are as big as possible to be sostainable weightwise and resistent enough. The matrix of their cells are soaked with substances similar to lignin to make them rigid. Those petals can also wrap all together to form a shield. This happens in "cold season"\* when the plant almost interrupts its normal metabolic cycle and during nights\*\*. The plant also gains nutrients from the ground where it penetrates with its roots deep enough to get water and other nutritional substances (this happens when the plant closes it self as a shield because in daytime it mainly keeps moving with a very slow speed).
The second creatures belong to one unique species (COACTOR VAGUS, wandering gatherer) whose individuals are organized in colonies. This species has a symbiotic bond with the Vileplume Magnus and uses it as a headquarter for the colony, where they can also have protection when it wraps-up as a shield. The colony is also organized very similarly to ants with a queen, many workers and some warriors that use to stay on the edge of the leafs to protect it from predators and potential threats. The queen stays almost for the whole life in the middle of the trunk where it generates newborns. The workers instead sliding through little channels in the trunk of the plant tend to spend the most of the time outside the colony collecting food that will be brought in the inside of the plant where the queen, the babies and the other Coactor themselves can consume it. The excrement are deposited in a specific part of the plant where it gets digested and used as an additional nutrient, useful to move.
The third creature (AVIS CALAMITATIS, Bird of Misfortune) is a 4, 2 meters tall predator that prays on  Coactor Vagus and uses to eat them directly from the ground or either leaning with the elongated neck over the huge leaves of Vileplumicus Magnus. Two of the 3 trunks it originally had became sensorial and social organs, also used to move the Coactors closer to the third trunk where they get eaten. The mouth(third trunk) is very flexible and can be elongated and also retracted inside the skull of the Animal. This species shows sexual dimorphism and the male (as seen in the other image) has very colorful characteristics that are used to attract females and compete with other males. In this animal the respiratory orifices moved to the front side of it so that while moving fast they can function also passively to absorb oxigen. Of the original 4 pairs of legs the one in the front of the animal is used to clean the respiratory orifice when external bodies accidentally get inside; one pair is technically useless and is getting wasted over time; one pair is used as the only locomotion sistem; and the last one changed function and now works as a tail to maintain balance (this is because on a planet with relatively low gravity not many legs are needed to obtain sustainable walking and equilibrium is fondamental at high velocity). This animal is very fast and has to escape from its natural predator: Canis Insectomorfus.
