In a study published in March , scientists tracked these typically elusive whales and reported one whale dived to the dizzying depths of 2, m 9,ft. The same whale stayed underwater, without taking a single breath, for minutes. The feat was exceptional, breaking new mammalian dive records in two categories simultaneously. But while the Cuvier's beaked whales have proved themselves as the champion divers, other marine mammals have also evolved, and honed, the ability to dive deep and long. Sperm whales routinely dive between m and m, Weddell seals go to m, and elephant seals can hold their breath for two hours. So the constant question we ask ourselves is: how do they do that?

Facts about sperm health and lifespan

Sign up for weekly baby and toddler emails Getting pregnant conception happens when a man's sperm fertilises a woman's egg. For some women this happens quickly, but for others it can take longer. Out of every couples trying for a baby, 80 to 90 will get pregnant within 1 year. The rest will take longer, or may need help to conceive. To understand conception and pregnancy, it helps to know about the male and female sexual organs, and to understand how a woman's monthly menstrual cycle and periods work.
