Data from: Parasitic fish embryos do a 'front-flip' on the yolk to resist expulsion from the host
<p><span>Bitterlings are brood parasitic fish which complete their early development in the internal gill spaces of freshwater mussels. Bitterling embryos have wing-like yolk sac extensions that help prevent them from being expelled from the gills by the water flow</span><span>. The ability to resist expulsion may be helped by the consistent 'head-down' position that all embryos adopt in the gills</span><span>. The mechanism behind this positioning is unknown. We hypothesise here that it might lie in a process of unknown function, specific to bitterlings. That process is <em>blastokinesis</em> — the rotation of the embryo on the yolk ball before hatching</span><span>. </span>We used time-lapse imaging, histology, X-ray tomography, and expression profiling of the genes <em>fgf8a</em>,<em> krt8</em>,<em> msx3 </em>and <em>ctslb</em> by <em><span>in situ</span></em><span> hybridization in the </span>pre-hatching and hatching stages of the rosy bitterling (<em>Rhodeus ocellatus</em>). We find <span>that blastokinesis is a gastrulation process that has been ventralized by the shape of the yolk mass. Furthermore, we show that bitterlings, unlike other teleosts, hatch mechanically without hatching enzymes, and we provide evidence that this is mediated instead by the apical tubercles on the yolk sac extension. Finally, our data suggest that blastokinesis is functional, because it represents the mechanism behind the optimal, 'head-down' positioning of the embryo. Our study provides an example of how selection pressures can lead to a suite of dramatic and coordinated modifications of early development.</span></p>
The Expulsion
Created by Henry Wiles (1838–1930) in White marble; 1871. Inscribed on back right corner of base: 'Henry Wiles/Sculptor/LONDON 1871'; and on the front and back of the socle: They hand in hand, with wandering steps and slow, Through Eden took their solitary way." This figure group shows a remorseful Adam and Eve makingtheir way out of the Garden of Eden, having disobeyed God and been expelled from paradise. The quotation on the base is the very final sentence of John Milton's epic poem Paradise Lost. https://data.fitzmuseum.cam.ac.uk/id/object/30941 This sculpture is dated 1871, and so must have been produced immediately after Wiles' return from Italy. It was bequeathed to the Museum by the Reverend Blore in 1885, just 14 years after it was made, so it is likely that he was the first owner and perhaps commissioned the work. Bequeathed by Rev. E.W. Blore, Senior Fellow of Trinity College, in 1885 (M.2-1885) Source: Objaverse 1.0 / Sketchfab

Figure 3. Per cent of Euxesta eluta copulating pairs, according to days after adult eclosion. Numbers above the diamonds are the sample sizes of pairs (mated and non-mated) according to age category (days after adult eclosion).

Figure 2. Ethogram depicting a typical mating sequence of Euxesta mazorca. The ethogram was constructed after 1-hour observations of 11 sexually mature pairs. The ethogram was reconstructed based on records of partial and complete records of mating sequences.
Figure 7 in Expulsion and consumption of male ejaculates by promiscous female Euxesta eluta and Euxesta mazorca (Diptera: Ulidiidae)
Figure 7. Mating networks of male and female groups of Euxesta eluta observed in the laboratory. Blue squares represent the males and the red circles represent the females. Arrows correspond to an observed copulation. Thicker arrows correspond to remating between pairs. Unconnected nodes represent individuals that did not mate.
