Abstract The mangrove killifish, Krypotlebias marmoratus, is an intriguing vertebrate species, known for its unusual sexual systems. It is one of two known self-fertilizing simultaneous hermaphroditic vertebrates, alongside the related Kryptolebias ocellatus. While individuals can be born as primary males, this is rare in the wild and most are born as hermaphrodites, around 60% then turning into secondary males at 3 to 4 years of age. K.

Abstract We apply a novel microscope architecture, the Exeter Multiscope, to the problem of acquiring image data in rapid succession from nine wells of a 96 well plate. We demonstrate that the new microscope can detect contraction in cardiomyocyte monolayers which have been plated into these wells. Each well is sampled using 500 x 500 pixels across a 1.4 x 1.4 mm field of view, acquired in three colours at 3.7 Hz per well.
