Australian species
Macroderma gigas is the largest Microchiropteran species next to Vampyrum spectrum

Large ears connected across the forehead by a ridge of skin, divided tragus. Large eyes, with large erect nose-leaf. Broad wings - not quick fliers but agile and manoeuvrable, but with primitive shoulder and elbow joints. Tail is short or absent but uropatagium is fairly well developed. No upper incisors. Upper canines project noticeably forward

Occur in tropical forests or savannahs, often near water, usually solitary.

Three species are carnivorous and two are mostly insectivorous. The carnivorous species have been known to feed on other bats, frogs, birds, lizards, fish, rodents, and large insects. Both insectivorous species have unique foraging strategies:
L. frons has flycatcher-like foraging style and C. cor uses a sedentary, close-to-the-ground scanning technique. Do not feed on blood.

May hunt using sight, sound, and echolocation. Echolocation - low-intensity, short, broadband

Megaderma, Cardioderma, and Macroderma roost in caves, rock crevices, buildings and hollow trees; Genus Lavia roosts in trees and bushes

Colour -
L. frons has yellow wings (known as the yellow-winged bat), M. gigas is pale lacking in pigmentation (known as Australian Ghost Bat)
