feeding and breeding grounds. Recent evidence indicates<br />

ovulation in loggerheads is mating-induced. Through the act of<br />

mating, the female ovulate eggs which are fertilized by the male.<br />

This is unique, as mating-induced ovulation is rare outside of<br />

mammals. In the Northern Hemisphere, loggerheads mate from<br />

late March to early June. The nesting season is short, between<br />

May and August in the Northern Hemisphere and between<br />

October and March in the Southern Hemisphere (Wikipedia).<br />

Loggerheads may display multiple paternity. Multiple paternity<br />

is possible due to sperm storage. The female can store sperm from<br />

multiple males in her oviducts until ovulation. A single clutch<br />

may have as many as five fathers, each contributing sperm to a<br />

portion of the clutch. Multiple paternity and female size are<br />

positively correlated. Two hypotheses explain this correlation.<br />

One posits that males favor large females because of their<br />

perceived higher fecundity (ability to reproduce). The other states,<br />

because larger females are able to swim more quickly to mating<br />

grounds, they have longer mating periods (Wikipedia).<br />

All sea turtles have similar basic nesting behaviours. Females<br />

return to lay eggs at intervals of 12–17 days during the nesting<br />

season, on or near the beach where they hatched. They exit the<br />

water, climb the beach, and scrape away the surface sand to form<br />

a body pit. With their hind limbs, they excavate an egg chamber<br />

in which the eggs are deposited. The females then cover the egg<br />

chamber and body pit with sand, and finally return to the<br />

sea. This process takes one to two hours, and occurs in open sand<br />

areas or on top of sand dunes. The nesting area must be selected<br />

carefully because it affects characteristics such as fitness,<br />

emergence ratio, and vulnerability to nest predators. Loggerheads<br />

have an average clutch size of 112.4 eggs (Wikipedia).<br />

Taxonomy<br />

Carolus Linnaeus gave the loggerhead its first binomial name,<br />

Testudo caretta, in 1758. Thirty-five other names emerged over the<br />
