Emperor penguins may be cute polar mascots, but they have a secret habit of child-snatching!

Titi monkeys (Callicebus cupreus) are studied not only for their monogamy, but also because fathers are actually the primary caretakers of the babies! Mothers will provide nourishment through nursing, but most of the time you’ll see the baby titi monkey clinging to their father for the first few months of their life. However, for families…

Monarch butterflies (Danaus plexippus), shown in caterpillar form above, are experiencing dramatic declines in population numbers. One method to help conserve species in decline is to rear and release captive individuals into the wild. Of course, this plan of action only works if captive-reared individuals are as capable as their wild counterparts. In a study…

Suddenly we are all spending a lot more time thinking about our immune systems—but what about the immune systems of the animals around us? For a long time it was thought that only animals with jaws and vertebrates had lymphocytes, but research with sea lampreys suggests otherwise. Researchers found lymphocyte-like cells in the gut of these charming…

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…

Did you know that March 22 is the International Day of the Seal? Seals are a part of the phylogenetic suborder Pinnipedia that consist of seals, sea lions, and walruses. Seals (Family: Phocidae) live in both the northern and southern hemispheres of our planet, from the cold, polar regions of the arctic and antarctic, to the…

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…

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…

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…
