Sunday Sketch: Social Distancing

We are all adjusting to a new normal, but for some animals social distancing is a way of life. Take the slow loris for example. These guys are happiest hanging out at home by them selves. One study found that these guys only spend 3% of their time in association with other slow lorises and…

Sunday Sketch: Thumbless but not helpless

Most primates have opposable thumbs that that help them grasp and manipulate objects. However, the spider monkey, Ateles geoffroyi, is one exception in which their hands have no thumbs at all! Instead, spider monkeys have a specialized prehensile (grasping) tail that is hairless on its underside and has a fleshy pad that is unique to each monkey…

Sunday Sketch: Get Ready for Aardvark Week

Aardvarks, Orycteropusafer afer, are ant eaters but aren’t anteaters. In other words, Aardvarks in Africa do primarily feed on ants and termites but actually aren’t very closely related to their anteater counterparts in South America. Many of their similarities arise due to convergent evolution associated with their diets. Aardvarks use their long, sticky tongue to…

Sunday Sketch: Child Labor

Like almost all activities in a social insect colony, nest building involves team work. Weaver ants, Camponotus (Myrmobrachys) senex, build elaborate nests made of stitched together leaves that are subdivided into small interconnected chambers. The work of tying these leaves together involves a surprising joint effort by both adults workers and larvae. Adult workers will carry individual…

Sunny Sketch: No Inkling of Ink

The dumbo octopus (genus Grimpoteuthis) is distinguished from its octopus brethren by its adorable ear-like fins that provide its namesake. However, there are also a few other characteristics that make this little creature unique. First of all, it is indeed a little creature compared to most other octopodes, with an average size of just 20-30…

Sunday Sketch: Birds of a feather

For most raptors, hunting is not a team sport. Harris’ hawks, however, play the game a bit differently. Although a few other raptors are known to hunt cooperatively, Harris’ hawks are by far the most cooperative and coordinated in their hunting behavior. They use many strategies for hunting that rely on coordinated maneuvers by each…

Sunday Sketch: Wiley as a Fox

Hunting is hard. Hunting in the snow? Even harder. A study on wild red foxes (Vulpes vulpes) in the Czech Republic indicates that these cunning hunters have an additional weapon in their arsenal—magnetic sensation! The study showed that foxes strongly preferred to pounce on their prey by jumping in the direction facing magnetic north east….

Sunday Sketch: Between a rock and a hard place

Long-tailed macaques (Macaca fascicularis) are one of the most common monkeys in southeast Asia. Some populations along the shore are found to use stones as tools to crack oysters, bivalves and various kinds of shellfish. This tool-related foraging technique is extremely rare among primates. The tool use behaviors are found only in some populations of monkey species in the same location despite sharing environmental…
