The nostrils can be closed by flaps, an adaptation for aquatic life. The ears can also be closed. Although the webbing on the feet does not extend farther toward the tips of the digits than in such genera as Paradoxurus, it is quite broad, and the fingers are capable of considerable flexion. A glandular area, merely three pores in the skin, is located near the genitals and secretes a mild scent material. The premolar teeth are elongate and sharp, adapted for capturing and holding prey, while the molars are broad and flat, for crushing.
Females have four mammae.
The otter civet is usually found near streams and swampy areas. It can climb well and, when chased by dogs, often takes refuge in a tree. While walking, it usually carries its head and tail low and arches its back. Although it is partly adapted for an aquatic life, its tail is short and lacks special muscular power, and the webbing between the digits is only slightly developed. Cynogale is thus probably a slow swimmer and cannot turn quickly in the water.
