While only a single sperm may fertilize the egg, getting to the egg can be facilitated, and
possibly enhanced, by sperm group dynamics. Examples range from the trains formed by …

In one of the first examples of how mechanics can inform axonemal mechanism, Machin's
study in the 1950s highlighted that observations of sperm motility cannot be explained by …

Organisms with conspicuous patterns are more easily detected by their predators and/or
prey, with consequences for their success when fleeing or preying, respectively …

Animal vision is incomplete without the ability to change the gaze that involves coordinated
control of eyes, head, and body movements (McCluskey and Cullen 2007). Saccadic eye …

Unlike most desert-dwelling animals, Cataglyphis ants do not attempt to escape the heat;
rather, they apply their impressive heat tolerance to avoid competitors and predators. This …

Sperm cells of all taxa share a common goal to reach and fertilize an ovum, yet sperm are
one of the most diverse cell types in nature. While the structural diversity of these cells is well …

Competition over reproductive opportunities among members of one sex often harms the
opposite sex, creating a conflict of interest between individual males and females. Recently …

Background Over their evolutionary history, corals have adapted to sea level rise and
increasing ocean temperatures, however, it is unclear how quickly they may respond to …

Competition to achieve paternity has coerced the development of a multitude of male
reproductive strategies. In one of the most well-studied examples, the spermatozoa of all …

In internally fertilizing species, sperm transfer is not always immediately followed by egg
fertilization, and female sperm storage (FSS) may occur. FSS is a phenomenon in which …
