Data from: Superfetation reduces the negative effects of pregnancy on the fast-start escape performance in live-bearing fish

Mike Fleuren, Johan Van Leeuwen & Bart Pollux
Superfetation, the ability to simultaneously carry multiple litters of different developmental stages in utero, is a reproductive strategy that evolved repeatedly in viviparous animal lineages. The evolution of superfetation is hypothesized to reduce the reproductive burden and, consequently, improve the locomotor performance of the female during pregnancy. Here, we apply new computer-vision based techniques to study changes in body shape and three-dimensional fast-start escape performance during pregnancy in three livebearing fishes (family Poeciliidae) that exhibit...
