Venezuelan red howler
slouatta seniculus latin

Venezuelan red howlers are most active in the morning, when the group is on the move to find another feeding spot.

The hindgut contains bacteria that digest leaves and makes up a third of the Venezuelan red howler's total body volume.

Venezuelan red howlers were observed feeding F. maxima fruit in Colombia.

The leaves of philodendrons are also known to be eaten by Venezuelan red howler monkeys, making up 3.1% of all the leaves they eat.

It is sometimes considered a subspecies of the Venezuelan red howler and classified as Alouatta seniculus arctoidea.

The white-fronted capuchin frequently travels with the common squirrel monkey and at other times with the tufted capuchin and Venezuelan red howler.

Like other New World monkeys, the Venezuelan red howler's dental formula (maxilla and mandible) is two incisors, one canine, three premolars, and three molars.

However, in 1997 a Venezuelan red howler (Alouatta seniculus) was reported to use a stick as a club to hit a Linnaeus's two-toed sloth, (Choloepus didactylus), that was resting in its tree.
