Description General Info
Description
Head and body length is 8–9 cm. Forearm 7 cm. Wingspan 45 cm. S. saccolaimus or T. saccolaimus (Payne et al., 1985) have dark-reddish brown or blackish brown upperparts which are irregularly marked with white patches. Their underparts are usually white, but in one colour phase it can be dark brown. They have no wing pouch or in other words, a poorly developed radio-metacarpal pouch. They have a distinct glandular pouch on the throat. The ear is short and broadly rounded with ribbing on the interior of the pinna with a short tragus which has a semicircular margin. It has long and narrow wings with black skin and translucent whitish portions. It is the largest species with the whitest wings.

General Info
Behavior
Pouched bat is a nocturnal species, primarily solitary, using complex vocalizations for communication. It employs a distinct nesting behavior—using tree hollows lined with leaves. Foraging typically occurs after dusk, often involving linear flight paths between feeding grounds. No distinct migratory patterns are observed. The species exhibits aggressive defensive behaviors, highlighting its territorial nature. Survival adaptations include acute echolocation for food detection.
Distribution Area
India and Sri Lanka through South-East Asia to Borneo, Sumatra, Java and Timor (Indonesia); New Guinea; North-East Queensland (Australia); Guadalcanal island (Solomon Islands). The species seems to have become absent in Australia. Bat-detector observations suggest that the species is very common in western Java, whereas further in the east (e.g. Bali) it is less common and its relative Taphozous melanopogon dominates in dry and coastal areas.
