One interesting phenomena in the Seychelles fauna is the Fruitbat or Flying Fox. Pteropus Seychellensis.
An important species for the ecosystems in the islands. The bat is big as a seagull, and you see them flying around all over also at day time. They are hunted for their meat by some of the locals.
About the catchy Halloween title…no worries, they only eat fruit and flower nectar. The pic is taken in Praslin island in February 2012 and turned upside down
