Cyclopes didactylussilky anteater

Ge­o­graphic Range

The Cy­clopes di­dacty­lus can be found in forests from South­ern Mex­ico to Bo­livia. It can also be found in Brazil.

Habi­tat

Cy­clopes di­dacty­lus in­hab­its the tree Ceiba, which has large seed pods that con­tain masses of a silky sil­ver­ish fiber. This serves as an ex­cel­lent cam­ou­flage for this tiny anteater, be­cause the sheen of the pods and the silky fur of the anteater are al­most iden­ti­cal. The silky anteater needs this pro­tec­tion be­ca­sue its preda­tors in­clude the harpy-ea­gle, ea­gle-hawks and the spec­ta­cled owl -- all of which have ex­cel­lent vi­sion. The silky anteater is ar­bo­real and very rarely de­scends to the ground.

Re­pro­duc­tion

Ges­ta­tion of the silky anteater is be­tween 120 and 150 days. It gives birth to a sin­gle young that the mother will place in a nest of dry leaves in a hole in a tree trunk. The young is raised by both par­ents, and the male some­times car­ries the young on his back. Both par­ents feed the young by re­gur­gi­tat­ing semi-di­gested in­sects for it to eat.

Lifes­pan/Longevity

Be­hav­ior

The silky anteater is noc­tur­nal and al­most never de­scends to the ground. It is very slow-mov­ing and is not typ­i­cally an of­fen­sive an­i­mal. In de­fense, how­ever, the silky anteater stands on its hind legs and grasps tree limbs with its hind feet and pre­hen­sile tail. It then hold its forefeet close to its face and strikes very quickly with its large claws. Be­cause they are so dif­fi­cult to find in the wild, lit­tle is known about the so­cial sys­tems of the silky anteater.

Com­mu­ni­ca­tion and Per­cep­tion

Food Habits

The silky anteater is strictly in­sec­tiv­o­rous. It feeds mostly on ar­bo­real ants and ter­mites (white ants), but has been known to oc­ca­sion­ally eat coc­cinel­lid bee­tles (Best). The anteater will eat on av­er­age 100 to 8000 ants per day. Cy­clopes di­dacty­lus is an op­pur­tunis­tic feeder that for­ages among the tree­tops and in­vades ants nests with its long sticky tongue.

Other Com­ments

Glossary

Neotropical

living in the southern part of the New World. In other words, Central and South America.

World Map

bilateral symmetry

having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.

chemical

uses smells or other chemicals to communicate

endothermic

animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.

motile

having the capacity to move from one place to another.

native range

the area in which the animal is naturally found, the region in which it is endemic.

sexual

reproduction that includes combining the genetic contribution of two individuals, a male and a female

tactile

uses touch to communicate
