![]() ![]() The smallest home ranges were occupied by low-weight females with dependent infants, perhaps reflecting social and energetic constraints. Adult males had larger home ranges than adult females, thus lending support to the hypothesis that males have adapted to the dispersion of females by occupying a large home range that overlaps the ranges of several adult females. Black-handed spider monkeys have yellow gray fur with yellowish-black or reddish sides and can weigh up to 15 lbs. When the size of home ranges derived from radio-tracking data for adult females was compared to size of ranges for adult females derived from observations, the results were not significantly different. 10 1 Spidermonkey has enhanced agility and enhanced acrobatic skills. Spidermonkey is very durable considering his size, as shown when he was able to survive seemingly unharmed after several large pieces of concrete fell on him. ![]() This species formerly was abundant in many parts of Central. Spidermonkey is highly skilled in hand-to-hand combat. ![]() The black spider monkey, Ateles paniscus, is one of three species of. The black spider monkeyalso known as the Guiana or red-faced spider monkeyis found in eastern South America in areas north of the Amazon River. However, the difference appeared to be owing to the presence of male ranges in the telemetric, but not the observational, data. The genus of spider monkeys ranges from Southern Tamaulipas in Mexico to Mato Grosso in Brazil. Spider monkeys are found in healthy tropical rainforests in Central and South America. The probability of encountering a radio-collared spider monkey in a three-hour search using radio telemetry (0.91) was much greater than using a visual search (0.20), and telemetric data resulted in a larger estimate of mean home range size than did observational data, when all subjects were compared. The average size of a spider monkey home range was 62.4 hectares however, range size varied with sex, and, for females, with the presence of a dependent infant. 11 12 Disproportionately long, spindly limbs inspired the spider monkey's common name. The ranging patterns of two male and five female spider monkeys ( Ateles geoffroyi) were studied with the use of radio telemetry in Santa Rosa National Park, Costa Rica. Spider monkeys are among the largest New World monkeys black-headed spider monkeys, the largest spider monkey, have an average weight of 11 kilograms (24 lb) for males and 9.66 kg (21.3 lb) for females. ![]()
