Facts about Aye-ayes
- 11
Aye-ayes possess a specialized middle finger with a ball-and-socket joint that rotates nearly 180 degrees, allowing them to fold it back when not foraging for insects within tree bark.
- 10
An aye-aye's brain comprises approximately 1.6 percent of its body weight, giving it one of the highest brain-to-body ratios among lemurs despite its small overall size.
- 09
Aye-ayes have a specialized eye-shine reflectivity that appears bright red or orange under light due to their tapetum lucidum, a reflective layer behind the retina that enhances night vision in their forest habitat.
- 08
Aye-ayes navigate their forest environment using echolocation-like clicking sounds at frequencies around 10-15 kilohertz to detect hollow cavities where insects hide within trees.
- 07
Aye-aye females in Madagascar give birth to a single infant after a gestation period of approximately 160 days, one of the longest among lemur species.
- 06
Aye-ayes possess a distinctive white stripe running down their spine that becomes more prominent as they age, serving as a visual recognition marker among individuals in Madagascar's forests.
- 05
Weighing only 2.6 kilograms on average, aye-ayes are the smallest living lemurs despite their widespread distribution across Madagascar's forests.
- 04
Aye-ayes possess a unique dental formula with continuously growing incisors, similar to rodents, making them the only primates with this specialized tooth adaptation.
- 03
Nocturnal aye-ayes have exceptionally large ears comprising about 29 percent of their head surface area, enabling acute detection of insect movement within trees.
- 02
Madagascar's aye-ayes produce ultrasonic vocalizations at frequencies up to 60 kilohertz, far beyond human hearing range.
- 01
Their extremely elongated third finger, measuring up to 7.6 centimeters, aye-ayes use for extracting insects from tree bark.
