North American bulldog bat (SciiFii)

A North American bulldog bat (Noctilio ursinus), also known as the northern bulldog bat and the northern fisherman bat, is a species of bat that originally did not exist, but has since been created by SciiFii and introduced throughout North America to help boost biodiversity. The North American bulldog bat uses echolocation to detect water ripples made by the fish and water insects (including water striders and water beetles) upon which it preys, then uses the pouch between its legs to scoop the fish/water insect up and its sharp claws to catch and cling to it. It emits echolocation sounds through the mouth like Myotis daubentoni, but the sounds are quite different, containing a long constant frequency part around 55 kHz, which is an unusually high frequency for a bat this large. The North American bulldog bat is a large bat, often with a combined body and head length of 10.9 to 12.7 cm (4.3 to 5.0 in). It generally weighs from 50–90 grams. Males tend to be larger than females, with the former averaging 67 grams and the latter averaging 56 grams. They also differ in fur color. Males have bright orange fur on the back while females are dull gray. However, both sexes have pale undersides and may have a pale line that runs down the middle of the back. Unlike greater bulldog bats (Noctilio leporinus) or the lesser bulldog bat (Noctilio albiventris), the North American bulldog bat has a thicker coat of fur to help keep it warm in the cold nights, like all other North American bats (both natural and genetically engineered), so it can even be found in areas as far north as Alaska. The conservation status of the North American bulldog bat is Least Concern due to successful conservation efforts, the North American bulldog bat's wide range and its tolerance to most of the human activities.
