Two types of blastokinesis are found in Dictyoptera: one is the “reversion type” (top) in blattoidean cockroaches and termites, and another the “non-reversion type” (below) in blaberoidean cockroaches and mantises.

A simplified phylogeny demonstrating gross differences in the manus morphology of modern tapirs. Bones with lighter colours (higher specificity %) represent higher levels of morphological difference between species, darker colours represent bones that are misclassified more frequently. Each tapir species is represented by a silhouette diagram demonstrating generalised appearance.

Testis structure of Daphnia magna, showing muscles in red, labeled with Phalloiden, and developing nuclei in blue, labeled with Hoechst.

EM observations on both, intermoult and postmoult stages of Xestoleberis species reveal that the “Xestoleberis-spot” system consists of three elements; two calcified chambers, a vesicle of electron-dense material and an uncalcified procuticle.

Plainfin midshipman females and type II males (an alternative male sexual phenotype) have prominent, horn-like rostral swim bladder extensions which are lacking in nesting type I males, that increase the proximity to the auditory end organs.
