Isurus is a genus of large, predatory shark belonging to the family Lamnidae. The term "isurus" is derived from the Greek words "isos" meaning equal or same, and "oura" meaning tail. These sharks are commonly referred to as mako sharks due to their resemblance to the common mako (Isurus oxyrinchus), the most well-known species in the genus Isurus.
Mako sharks are renowned for their streamlined body shape, powerful muscle structure, and exceptional swimming abilities. They typically have a slender, elongated body with a pointed snout, large eyes, and multiple rows of sharp, triangular teeth, adapted for feeding on a variety of prey such as fish, squid, and occasionally even marine mammals.
Isurus species are known for their exceptional speed and agility, often reaching remarkable speeds up to 45 miles per hour (72 kilometers per hour). They possess a crescent-shaped tail, also known as a lunate tail, which allows them to swiftly maneuver through the water with incredible efficiency.
These sharks are found in both temperate and tropical waters worldwide, predominantly in offshore and pelagic habitats. While the common mako (Isurus oxyrinchus) is the most widespread species, other known species within the Isurus genus include the longfin mako (Isurus paucus) and the extinct broad-tooth mako (Isurus hastalis).
Due to their impressive size, striking beauty, and significant ecological role as apex predators, Isurus species hold immense importance in marine ecosystems. Nevertheless, like many shark species, they face threats from overfishing, habitat degradation, and accidental capture in fishing gear. Conservation efforts are crucial to ensure the preservation and survival of these remarkable creatures.
