Sabre teeth - the long, sharp, blade-like canines found in extinct predators such as Smilodon - represent one of the most extreme dental adaptations in nature. They evolved at least five times throughout mammalian history and are a classic example of convergence, which is when similar structures evolve independently in unrelated animal groups.

While terrestrial breeding in polygynous species of pinnipeds allows for observations of reproductive behavior (Atkinson, 1997), similar opportunities are limited for cryptic, nonpolygynous, aquatic-breeding species. The isolated nature of solitary leopard seals (Hydrurga leptonyx; Southwell et al., 2012) restricts data collection on their reproductive behavior.
