Pteropus vampyrus malaccensis (scientific name: Pteropus malaccess) is one of the subspecies of giant flying fox and the largest bat in the world. The body length is 20-25cm, the weight is about 600- 1 100g, and the maximum wing width is 183cm. It has a pair of big eyes, a long nose like a dog and long, pointed ears. The lower body hair is long and varies in color from black to brown.
A few to thousands live in groups anywhere. When you enter the nearby habitat at sunset, you can fly to the predation area silently, up to 50 kilometers away. They usually circle around a fruit tree before landing, forming a noisy foraging group, forming several to more than 50 bats. Unlike many other bats that use echolocation navigation, Malay flying foxes rely on vision to find their homes at night. They usually feed on the fruits of rambutan, fig and Langsat fruit trees, and also eat nectar, coconut and durian trees.
The researchers investigated the habitats of 33 Malayan flying foxes in Malaysia and compared the number of Malayan flying foxes with the number of hunting licenses issued by Malaysian authorities. It was found that about 22,000 Malayan flying foxes were hunted through legal procedures every year in Malaysia Peninsula (2009), but the number of illegally hunted flying foxes was unknown.
According to the investigation in 2009, the analysis of relevant data shows that the actual number of Malayan flying foxes hunted cannot be estimated, and the most optimistic estimate is 500,000. At this rate, this species will disappear from the earth in the longest 8 1 year.
