Schneider's Roundleaf Bat (Hipposideros speoris) lives in tropical rainforest across South Asia. It feeds on insects and spiders. Its conservation status is Least Concern.
Fascinating facts about the Schneider's Roundleaf Bat
- Schneider's roundleaf bat is a very small species, and its reproductive anatomy reflects this diminutive size. It possesses a tiny baculum, which is just 0.57 mm in length, ending in a blunt tip with a slightly expanded base. Such a minute bone is consistent with the bat's overall tiny stature and the delicate nature of its skeletal structures. The short length of the baculum highlights how compact the entire animal is compared with many other mammals.
- The nose leaf of Schneider's roundleaf bat is distinctive, bearing three extra leaflets where the outer one is smaller than the other two. Prominent lappets sit beside the nostrils, providing a clear external marker that separates it from its congeners. A frontal sac is also present above the leaf-nose, adding another unique facial feature. Together these characteristics give the species a recognisable facial architecture not seen in other Hipposideros bats.
- When hunting, Schneider's roundleaf bat emits echolocation calls that last between 5.1 and 8.7 ms and are produced at very high pulse repetition rates of 22.8-60.6 Hz. These calls have duty cycles ranging from 23 % to 41 %, meaning the bat spends a large proportion of each second broadcasting sound.
- When a newborn tries to cling, the mother turns her body about an angle of 45° and partly spreads her wing membranes, creating a stable platform for the infant. This posture lets the baby grasp the mother's pubic teats and release its grip on the rock. After the infant attaches, it turns toward the mammary glands and repeatedly stretches one or both wings while suckling.
- It is commonly found and widespread across its entire range, forming colonies that can contain up to 1,000 individuals. The species inhabits a variety of roosts such as caves, underground cellars, old forts, temples and tunnels in both dry plains and forested hillsides. It occurs from sea level up to 1,285 m elevation in India, Sri Lanka and Myanmar, occupying subtropical or tropical dry forests, caves and even urban areas.
