For no particular reason, I was looking through Mary’s lemur photos. I saw these and thought them particularly interesting: they show a male Indri Indri indri bark-eating. What makes this individual unusual is that he was missing his left eye (or, at least, had a very damaged left eye). I don’t know why and don’t know if Mary does either.
As you’ll know, indris are the largest extant lemurs, reaching 720 mm in maximum length (snout to tail) and weighing up to 7.5 kg. That’s big, but it doesn’t approach the sizes reached by some of the extinct species, the biggest of which exceeded 200 kg. Indris are pretty variable in colour, and the neatly marked black-and-white individuals you often see on TV are not typical of the species across its range: those are southern animals. Those in the north lack distinct white patches on the limbs and back and may have a pale facial disc. Of course, the present range of indris is very restricted compared to their historical range: today they occur only in the central-eastern and north-eastern rainforests, but fossils show they previously occurred right in the north and as far south as the central highlands at least (Garbutt 1999).
For previous Tet Zoo musings on lemurs, there was a brief discussion on new woolly lemurs and sportive lemurs here. Yikes, that’s about it. No no, wait… there’s the sifaka stuff here on ver 1 and a brief mention of the Alaotra lemur here.
