Ultrastructure of spermatozoa of the wooly opossum Caluromys philander
Journal of Ultrastructure Research, 1970The fine structure of spermatozoa of the wooly opossum was analyzed with particular attention paid to morphological changes attending pairing of the spermatozoa during passage through the epididymis. Before pairing, the spermatozoa are shaped something like a carpet tack. The flat anterior face of each spermatozoon is covered by an acrosome.

Genetica, 2013
Caluromys is considered to be one of the most ancient genera of extant marsupials and is positioned among the basal taxa of the family Didelphidae. At least two species occur in Brazil, C. philander and C. lanatus, both of which have 2n = 14 chromosomes. For the first time, we present evidence of an intrapopulation polymorphism of the sexual chromosome

Use of zygodactylous grasp by Caluromys philander (Didelphimorphia: Didelphidae)
Mammalian Biology, 2010The present report aims to quantify the use of zygodactylous (opposability of digits II to III) grasping in relation to positional modes and support size and orientation, in the highly arboreal, walking/climbing woolly opossum, Caluromys philander. For this purpose, four captive adult C.

Journal of Human Evolution, 2008
A key feature in primate evolution is a foot with a divergent opposable hallucal metatarsal bearing a large peroneal process. Extant primates are characterized by a powerful hallucal grasp-an either "euprimate" or "plesiadapoid-euprimate" ancestor acquisition-that facilitates the exploitation of fine branches, an ability that increased the fitness of ...

Behavior and maintenance of the woolly opossum (Caluromys) in captivity.
Laboratory animal science, 1978Circadian activity, general behavior, dietary requirements, and reproductive activity were recorded in a small laboratory colony (four females, six males) of two species of the woolly opossum (Caluromys lanatus and C derbianus) over a period of 3 years. The two species were indiscernable in all aspects of their behavior.
