Ancient vampire bat (SciiFii)

The ancient vampire bat (Desmodus archaeodaptes) is a species of vampire bat that originally lived throughout many of the warm parts of eastern North America during the Pleistocene and was once extinct, but has since been brought back from extinction by SciiFii and reintroduced throughout the modern southeastern United States to help boost biodiversity. When SciiFii announced the recreation of this species, many people were concerned that this species could spread diseases and viruses, including rabies, however, thanks to SciiFii using genetic engineering, the ancient vampire bats are completely immune to diseases and viruses, so they do not carry any known disease or viruses, making the ancient vampire bats completely harmless unlike their South American relatives. The ancient vampire bat is an rather average-sized bat, growing on average to be about 9 cm (3.5 in) long with a wingspan of 18 cm (7 in). It commonly weighs about 25–40 grams (2 oz), but its weight can drastically increase after a single feeding. Like its relatives, the ancient vampire bat is hematophageal, feeding on blood from living specimens of larger mammals, which it bites at night, while the larger mammal is sleeping. The species is highly polygynous, and dominant adult males defend groups of females. It is one of the most social of bat species with a number of cooperative behaviors such as social grooming and food sharing. The conservation status of the ancient vampire bat is Least Concern due to successful conservation efforts, the ancient vampire bat's wide natural range and its tolerance to most of the human activities.
