Albeit these aren't blood-suckers... They're baby fruit bats. Fruit bats, sometimes called Mega Bats or Flying Foxes, actually range in size depending on species, but can get to as large as 16 inches tall with a 5 foot wingspan. As the name implies, they eat fruit and nectar, and are major seed distributors and pollinators where they live.
How do I say it... oh yeah. I WANT ONE.
