Close relatives of the cutlassfish, saberfish are a species of saltwater swimmers only found throughout the coast of Australia, Papua New Guinea and New Zealand. Their meat is nutritious and tasty, but excessive consumption can quickly lead to heavy metal poisoning. Adult individuals are solitary and meet up in winter to mate, while young ones go around on large schools of over 100 individuals. Saberfish possess an upper fin finely coated with what appears to be a thin layer of iron-laced proteins. This creates a sort of blade that they use when under attack, by attempting to "cut" the enemy. Most predators are used to hunting saberfish and attack from vulnerable angles like the front and underside. Saberfish can ironically be impaled with a stick and used as a makeshift cutting utensil.
