Spider monkeys

Similar constant checking across the cycle occurs in the Spider monkey (Ateles), where males directly sniff and nasally contact the females complex labial folds. The external genitalia lack visual peri-ovulatory alterations, hence usage of the AOS may occur. It is however unestablished in this, as in many other species without overt vulval colour change (Klein, 1971 Hunter et al., 1984).

New World monkeys are found from southern Mexico to southern Brazil, and are grouped into two separate families. Marmosets and tamarins are in the family Cal-litrichidae, while the capuchins, titis, night monkeys (or douroucoulis), sakis, howlers, wooly monkeys, and spider monkeys are included in the family Cebidae. The cebid monkeys are sometimes referred to as capuchinlike monkeys for lack of a better non-scientific term to separate them from the marmosets and tamarins. 

Cebid monkeys include capuchins (Cebus), night monkeys or douroucoulis (Aotus), titis (Callicebus), squirrel monkeys (Saimiri), sakis (Pithecia), bearded sakis (Chiropotes), uakaris (Cacajao), howler monkeys (Alouatta), spider monkeys Ateles), the woolly spider monkey (Brachyteles arachnoides), and woolly monkeys (Lagothrix). 

The cebid monkeys vary in size from the squirrel monkey (S. sciureus) with a body length of 10 in (25 cm) plus a 15 in (38 cm) tail, and a weight of about 1.5 lbs (0.68 kg), to the woolly spider monkey, or muriqui, which has a body length of 18 in (46 cm), plus a 30 in (75 cm) tail, and weighs about 35 lb (17.5 kg). The males and females of most species of cebid monkeys are approximately the same size, but the two sexes often have different colorings, a phenomenon known as sexual dimorphism. 

The subfamily Atelinae includes the spider monkeys, the woolly spider monkeys, and the woolly monkeys. These monkeys are as large as howler monkeys but thinner. 

The long tail is especially useful because, unlike many other monkeys, spider monkeys do not have an op-... 

In coastal parts of Brazil, the spider monkey s territory is taken over by the woolly spider monkey or muriqui Brachyteles arachnoides). The woolly spider monkey is the heaviest monkey in Brazil, weighing 35 lb (16 kg) it has the chunky body and thick fur of the woolly monkey but lacks a thumb. It is lighter brown in color than most of its relatives.

Other herpesviruses of animals. Herpesviruses that have been found in squirrel and spider monkeys have been shown to have oncogenic potential. Other oncogenic herpesviruses include Marek s disease virus of chickens (206 p.209), the Lucke virus of frogs, and Herpesvirus sylvilagus of the cottontail rabbit.
