AYE Aye aye aye! (begin Crazy Train)

I’ve been mulling over this Endangered Ugly Thing since the inception of this blog. Is it cute or hideous¹? Well, it was originally classified as a rodent, and the native Malagasy consider it a portent of death, so we welcome the world’s largest nocturnal lemur to Endangered Ugly Things.




























The aye-aye (Daubentonia madagascariensis) has massive eyes and ears for better managing its nightlife. Like all lemurs², they live in the dense jungles of Madagascar. Unlike the rest of the lemurs, their hands are long and spindly, with a skinny, elongated middle finger (I can’t find the average length, though). Aye-ayes tap the wood with this finger and listen for the correct echo with their huge ears, and gnaw a hole in the wood with their rat-like teeth before they begin rummaging for the grubs with their twiggy middle finger, filling much the same role as our woodpeckers. They will also eat fruit or vegetable material (or eggs), extracting the pulp using this finger³.

These raccoon-sized lemurs are usually solitary, moving along the treetops. Males’ home ranges are large (100-200 hectares) and encompass many females’ ranges. They tend to be curious and unafraid of people. Territories are marked by scents. When breeding season comes around, the females scream out to advertise their availability. The babies are weaned for about 7 months, and the females mate every three years.

Habitat destruction is the major threat to the aye-ayes, along with just about everything living in Madagascar. When agriculture invades their usual haunts, they will feed on the fruits, such as coconuts, becoming pests. Also, as mentioned in the beginning of the post, many Malagasy natives believe them to be omens of death, or other like portent, so they get killed on sight.

Many of the places aye-ayes live are protected, helping to save their habitat, and they are being introduced into other areas. There is a law against killing them, but it is not well enforced. Breeding programs exist at various zoos and the Duke University Lemur Center. But be warned, the little aye-ayes are even uglier.

¹I get the feeling that the guys at Ugly Overload get this issue all the time.
²Which, appropriately enough, comes from the Latin “spirits of the night,” at least according to Wikipedia.
³ARKive has tons of wonderful pictures and videos, and it looks so much creepier when it’s moving.
