White-bellied spider monkey

(Ateles belzebuth)

Description

Ateles belzebuth has a dental formula of 2.1.3.3.As far as patterns within the teeth,there is a lot of variation but the following are often found within Ateles.Larger incisors and small molars reflect the largely frugivorous diet,with a diastema separating the upper canines from the upper incisors,for the lower incisor.The upper premolars have one to two cusps,with the first premolar having only one cusp,a paracone.The second premolar has a paracone and protocone cusp connected by transverse crest.The third premolar has three cusps,paracone,metacone,and protocone,with the metacone and protocone connected by a crista oblique.There is a recorded hypocone on the third premolar.In the bottom premolars,the first premolar has one cusp although it can be bicuspid.The second and third premolar generally have 2-3 cusps,although the second bottom premolar has an entoconid and hypoconid and the third bottom premolar in belzebuth has five cusps with a small hypoconulid.Upper molars generally have four cusps although the third molar may not have a hypocone (might even have only two cusps).With the bottom molars,there are generally four cusps and a fifth cusp on the third molar.(Why is the format of this species teeth so important that it deserves its own section? Is it very unusual from other similar species? There is a section needed for the species life cycle and how it survives,meaning food,and what climate would you observe this species in.)
