Bladesnapper

The bladesnapper replaced its ancestor in the Fermi Island. Its lower jaw has a sharp edge to help it cut up prey for eating; if it feels threatened or aggressive, it can use its blade-jaw to slice at opponents. Its neck is longer to help it reach prey in the water, as well as use its blade with greater dexterity. Other than this, its the same as its ancestor.

Individuals live for 5 years, maturing the in first year. Individuals nest in groups of 20-50 called "barracks"; while they return to the same place to nest, they hunt alone or in mating pairs. As nesting space became more scarce, some populations moved into the temperate parts of the island. Parents mate for life and rear clutches of 2-3 chicks, which are laid in the warmer months and take 3 months to hatch.
