I find it quite shocking that I have not written about pangolins yet. These guys are some of my all-time favourite mammals, and yet I’ve ignored them for nearly four years of blogging and over four hundred posts. I know I’ve considered writing about them, but perhaps the time was never quite right. Well, today is the big day for pangolins, because these amazing animals are going to get their very own blog post!
There are eight species of pangolins, all of which belong to the family Manidae. Pangolins can be found in Africa, India and southeast Asia. All species live in tropical areas, though they differe in their lifestyle choices, with some being arboreal and some preferring to live on the ground. Most pangolins are nocturnal, with only one species, the long-tailed pangolin, being active during the daytime.
Pangolins vary in size depending on the species, ranging from 30 to 100 cm long. The most notable feature of pangolins is their overlapping scales that look extremely out of place on a mammal. These scales are made of keratin, and harden as the animal matures. They may look funny, but the scales provide pangolins with an excellent mode of defence. When a pangolin feels threatened, it curls up into a ball, tucking its head under its tail, leaving the predator with only a hard, spiky ball to look at.
Pangolins are at home in a number of different environments. They happily climb trees, with some species of arboreal pangolin having prehensile tails that they can use while climbing. Ground dwelling pangolins dig burrows, which can reach depths of three and a half meters. Some species of pangolins will walk with their front claws folded under their feet, and others will sometimes rear up and perform some behaviours bi-pedally, even walking on two legs for small periods. But climbing, digging and walking aren’t the only things pangolins can do; they can also swim quite well. That’s pretty impressive for such awkward looking animals.
So what do these strange and wonderful animals eat? Pangolins like to feast on tasty and nutritious insects. They use their strong claws to dig up bug nests in trees and on the ground, and then stick out their tongues to gobble them up. Pangolins have incredibly long tongues, which are coated in saliva from glands in the animals’ chests, making them extra sticky, and thus the perfect insect grabbers. Though insects are tasty, they are small, so pangolins have to eat a lot of them. They eat between 140 to 200 g of food a day, and are quite picky, generally eating only one or two species of insect.
Another weird thing about pangolins: they don’t have teeth. They get around this by having a very muscular chamber in their stomachs, complete with spikes that help grind up food. Pangolins will also swallow stones or pebbles that assist in grinding up any food they eat.
Pangolins live solitary lives, coming together only to reproduce. There is no set mating seasons, and pangolins usually mate once a year. Pangolins are a little backwards when it comes to mating — instead of males heading out to find mates, females are lured to spots marked by male pangolin urine or dung. There is some competition over females; when this occurs male pangolins establish dominance by swinging their tails at one another.
Gestation in pangolins ranges from 70 to 140 days. Litter size depends on the species, and can be one to three baby pangolins. When they are born, the scales of young pangolins are soft (imagine giving birth to a baby armoured with spiky scales!), and these harden after several days. While the scales are still soft, mother pangolins are very protective of their young, wrapping themselves around their babies if they feel threatened. After a few weeks the young pangolins ride around on their mother’s tails, and they are weaned at around three months of age. They become sexually mature at two years of age.
There is, of course, a sad side to the pangolin story. They are hunted for their meat and their scales, as pangolin meat is considered a delicacy in many areas, and their scales are thought to have medicinal qualities. Pangolins have the upsetting title of being the Most Illegally Trafficked Animal in the world. All pangolin species are currently threatened, and two are listed as critically endangered. Though they are protected species, illegal trafficking remains a serious threat to the pangolin population. On that sad note, I’ll leave you with a cute drawing of a baby pangolin.
