The two species of two-toed sloths have two toes on their forelimbs, but three on their hindlimbs. While the gentle three-toed sloths eat only leaves of a few species, and are notoriously difficult to maintain in zoos, captive two-toed enthusiastically eat all sorts of common fruits and vegetables, as well as monkey chow, and easily live for decades in captivity. Of the two species of two-toed Sloths, both are found in South America, but only Hoffman's occurs in Central America as well.
At times, the DWA troop of Red howler monkeys, unique in North America, are heard long before they are seen. The mechanical-sounding, rumbling growl is produced by an enormous larynx (voice box) and can be heard three miles away. The only animal sound that is louder is made by Blue whales. The howlers are often next to the ceiling of their high enclosure. While this South American primate was notorious for being difficult to keep in zoos, it has done well at the DWA, where a number have been born and raised.
Reaching a length of a foot-and-a half and weighing less than five pounds, this is one of the smaller members of the Jack family, which includes such well-known game fishes as the Amberjack, as well as the Yellowtail featured in Sushi bars. Despite its small size, it is considered delicious, like its relative the Pompano. It is found in large schools in the Tropical Atlantic and the Gulf of Mexico and is common along the Texas coast. The peculiar head structure which gives it its name, has made it popular as a public aquarium animal for many years.
