. The co-occurrence of eggs and N1-larvae in the same brood pouch is rarely found. This indicates that the embryos were asynchronously hatching from the egg membrane shortly before and during fixation. The observed strong size differences between the hatchlings are clearly due to the obligatory stretching of the abdomen during and shortly after hatching. Adoption of eggs or larvae from other mothers appears unlikely in this case: in experiments of
