Yellow Breasted Venthi
90 cm (head to tail) 120 cm (primary wingspan)
Adaptations: K. pectoflavus is a four winged flying predator that has developed three primary traits that set it aside from its ancestor, K. flavocallus.
The first being a modification to its teeth. K. pectoflavus now sports new sets of sharp teeth in addition to its venom-delivering fang. On the top jaw, the fang is flanked by two teeth on either side. The bottom jaw now features four that interlock with the five on the top. These teeth originate from the same source of the fang. They began as bumps in the jaw, and eventually developed into bone outgrowths encased in a keratin-like substance. These teeth allow the Venthi to more securely grab prey when injecting venom and also lessen the stress on the previous single fang, lowering the chance of it breaking and crippling the Venthi. These teeth also allow for the second major adaptation involving feeding.
Feeding: K. Pectoflavus has changed its feeding behavior. Instead of swallowing prey whole like its ancestor the Yellow Breasted Venthi now tears prey apart with its newly developed teeth before swallowing prey chunk by chunk. It holds its prey down with its forearms and tears at it with its mouth. This is advantageous as once swallowed the food is broken up into smaller pieces allowing for more efficient digestion. The trade off for this however is that it takes a longer time to feed. This also severely decreases the resting time that K. flavocallus and its ancestors needed while digesting large meals. In addition eating already killed prey piece by piece reduces the risk of suffocation from larger prey items swallowed by more ambitious Venthis. This isn't needed for sufficiently small organisms (around 20cms and smaller) which are neither injected with venom nor torn apart.
K. pectoflavus hunt by diving at prey from above or behind, grabbing their target with their prehensile tail, and injecting it with venom. They then back off and wait from a distance until their prey dies before beginning to feed.
K. pectoflavus is a voracious predator and feeds on many organisms smaller than it in Zone D such as B. purpla, B. spikus, D. herbimothus, F. prakerus, J, fucopinna, K. killiskippus, P. velocius, T. gigalsothus, T. takydromus, D. chadensis, and D. mothus. The Yellow Breasted Venthi will typically only feed on larger prey such as T. gigaslothus, D. herbimothus, and D. mothus when hunting with a mate.
Reproduction: The third major change is a social one. Male and female pairs now live socially for periods around mating time, instead of the male simply impregnating the female and leaving. In addition to the male attracting a female with bright colored wings, rudders, and a newly evolved crest (now having patterning on more areas such as wrists, neck, and chest, drawing more attention to these areas and making it more obvious if these areas a damaged, indicating poor behavior or genes that more often lead to injury) mating pairs of K. pectoflavus now undergo a "trial period" before mating where the male proves to the female that he is a capable hunter, displaying that it has worthwhile genes. The female stays with the male through pregnancy, occasionally going on hunts together or the male going alone. This behavior began when females would begin to stick with males and bully them out of food to increase survivability. This is beneficial, as it increases female survivability. Once the eggs are laid, the male and female go their separate ways.
Fertilization takes place internally and females lay a camouflaged clutch of 8-10 purple eggs in the tops of trees.
