Hidden amongst the coral rubble and sandy bottoms of the Maldives lives one of the ocean’s most remarkable creatures — the mantis shrimp. Although most species measure only 10 – 20 cm in length, they possess abilities that rival those of much larger animals.

Despite their name, mantis shrimp are neither mantises nor true shrimp. They belong to their own unique group of crustaceans called stomatopods and have evolved into highly specialised predators over millions of years.

There are two main types of mantis shrimp: “smashers” and “spearers.” Smashers use their powerful club-like appendages to crack open the hard shells of crabs, snails, and clams. Their strike is one of the fastest movements in the animal kingdom, accelerating with incredible speed and force. The impact is so powerful that it briefly creates tiny bubbles in the water. When these bubbles collapse, they generate a second shockwave, meaning prey is often stunned or killed by two separate impacts from a single strike.

Spearers, on the other hand, hide buried in the sand and ambush passing fish with sharp, barbed appendages that shoot out in the blink of an eye.

Perhaps even more astonishing than their punch is the mantis shrimp’s eyesight. Their eyes can move independently and are considered among the most complex in the animal kingdom. While humans have three types of colour receptors, mantis shrimp possess many more and can detect ultraviolet as well as polarised light. Scientists continue to study their vision, hoping it may inspire advances in cameras, medical imaging, and optical technology.

For divers, spotting a mantis shrimp is always a treat. You may notice a pair of curious eyes peering from a burrow before the animal quickly disappears underground. They are generally shy and prefer to avoid confrontation, despite their fearsome reputation.

The next time you’re exploring a Maldivian reef, take a closer look at the cracks and crevices. One of nature’s smallest predators may be watching you with the most extraordinary eyes in the ocean.
