Aposematic signaling and seasonal variation in dorsal pelage in a venomous mammal.

In mammals, colouration patterns are often related to concealment, intraspecific communication, including aposematic signals, and physiological adaptations. Slow lorises ( spp.) are arboreal primates native to Southeast Asia that display stark colour contrast, are highly territorial, regularly enter torpor, and are notably one of only seven mammal taxa that possess venom.

Risky Business: The Function of Play in a Venomous Mammal-The Javan Slow Loris ().

Immature mammals require opportunities to develop skills that will affect their competitive abilities and reproductive success as adults. One way these benefits may be achieved is through play behavior. While skills in developing use of tusks, antlers, and other weapons mammals have been linked to play, play in venomous animals has rarely been studied.

Slow lorises use venom as a weapon in intraspecific competition.

Animals have evolved an array of spectacular weapons, including antlers, forceps, proboscises, stingers, tusks and horns [1]. Weapons can be present in males and females of species needing to defend critical limiting resources, including food (rhinoceros beetles, Trypoxylus) and territories (fang blennies, Meiacanthus) [1-3]. Chemicals, including sprays, ointments and injected venoms, are another defence system used by animals.

Venom in Furs: Facial Masks as Aposematic Signals in a Venomous Mammal.

The function of colouration in animals includes concealment, communication and signaling, such as the use of aposematism as a warning signal. Aposematism is unusual in mammals, and exceptions help us to understand its ecology and evolution. The Javan slow loris is a highly territorial venomous mammal that has a distinctive facial mask and monochromatic vision.

Conservation implications of primate trade in China over 18 years based on web news reports of confiscations.

Primate species have been increasingly threatened by legal and illegal trade in China, mainly for biomedical research or as pets and traditional medicine, yet most reports on trade from China regard international trade. To assess a proxy for amount of national primate trades, we quantified the number of reports of native primate species featuring in unique web news reports from 2000 to 2017, including accuracy of their identification, location where they were confiscated or rescued, and their condition upon rescue. To measure temporal trends across these categories, the time span was divided into three sections: 2000-2005, 2006-2011 and 2012-2017.

Survey of practitioners handling slow lorises (Primates: ): an assessment of the harmful effects of slow loris bites.

Slow lorises () are one of six venomous mammals, and the only known venomous primate. In the wild envenomation occurs mainly during conspecific competition for mates and territory, but may also be used as an application against parasites or for predator defense. Envenomation in humans is documented, with the most extreme accounts detailing near-fatal anaphylactic shock.
