In additional to this, they can track the sloth’s acceleration data – presumably this isn’t very fast, but a measure of this can be used to work out their energy expenditure.
Best of all, the devices are open-source and comparatively cheap, meaning they can be easily used in projects around the world. This is especially important for their native home among the mangroves of Isla Escudo de Veraguas, a small island around 17 kilometers (10 miles) north of mainland Panama. The mangroves of this idylic homeland – the only place where the sloths can be natively found – face a threat of destruction, further adding to the plight of the pygmy three-toed sloth.
