White-chested agropelter (SciiFii)

The white-chested agropelter (Xenoanthropithecus cebus), also known simply as the agropelter, is a species of New World primate, most closely related to the squirrel monkeys (Saimiri), that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests across the Caribbean Islands to help boost biodiversity. The white-chested agropelter is a medium-sized New World monkey and can grow to be about 32 to 57 centimetres (13 to 22 inches), a tail length of 38 to 56 centimetres (15 to 22 inches), and a weight of 1.9 to 4.8 kilograms (4.2 to 10.6 lb). The white-chested agropelter is considered both frugivorous and insectivorous, preferring fruits on branches and various insects. The white-chested agropelter has longer limbs than most monkeys, with its limbs being three-quarters its overall body length, with equally longer hands and feet with longer fingers/toes to match. Like apes and unlike most monkeys, it has ball-and-socket joints on the wrist, which greatly reduces the amount of energy needed in the upper arm and torso, while also reducing stress on the shoulder joint. The white-chested agropelter has thicker soles on the feet so it could better gain access to unsuitable terrain. It also has taller cheekbones to support more muscles to the jaw. It has a combination of thick enamel and large teeth, similar to those of baboons and chimpanzees. All noticeable differences, but perhaps not as noticeable as the brain itself. While most simians have brains of varying size ratios, white-chested agropelters have just one same ratio--2.7% of their overall body weight. The white-chested agropelter's olfactory bulb, a piece of the brain dedicated to smell, is 40% larger than most simian primates. The hippocampus, a piece dedicated to memory, is 32% larger. The white-chested agropelter has strong memory but also decision-making and emotional responses. The inner ear canal is identical in length to most simian primates, but it is 70% wider. While the outer ears are still symmetrical, the inner ears aren’t, a lot more like owls than most mammals. This is pretty efficient, particularly when its night vision is poorer than its hearing. This is because the occipital lobe, the region dedicated to the sense of sight, is twice as large in proportion as that of other simians, which means that it has higher numbers of cones, photoreceptors dedicated to color vision. Whereas humans have only five million cones, an average white-chested agropelter can have as much as 24 million. Another difference is in the white-chested agropelters' blood. They have high concentrations of plasma, which is pretty useful in warding off infections. But perhaps the most unique thing about the white-chested agropelter is its bisexual behavior. In a troop, all the males mate with each other before mating with all of the females, who also mate with each other. That way, every member in the troop gets to raise their young, regardless of who the real father or mother is. Both sexes produce energy-rich milk, and they are not confined to feeding growing babies. Even the adults feed on each other's milk, sometimes to refuel themselves, sometimes as a way of contributing sex appeal. Whereas reports of bisexual white-chested agropelters crop up to the scientific community in droves, there is virtually nothing on the existence of hetero- or even homosexual white-chested agropelters. The conservation status of the white-chested agropelter is Least Concern due to successful conservation efforts, the white-chested agropelter's wide range and its tolerance to many of the human activities.
