The Peacock Mantis Shrimp: A Vibrant and Fascinating Underwater Marvel
The underwater world is full of incredible creatures, but few are as colorful, captivating, and downright powerful as the peacock mantis shrimp (Odontodactylus scyllarus). Found in the warm tropical waters of the Coral Triangle, including the dive sites around Bohol, this crustacean has become a favorite among underwater photographers, marine biologists, and scuba divers. Its dazzling appearance and unique behaviors make it a must-see for divers exploring the region.
At Sierra Madre Divers, we often encounter this incredible animal during dives, and it never fails to leave a lasting impression. In this article, we’ll dive into what makes the peacock mantis shrimp one of the most extraordinary marine species you’ll ever encounter.
Meet the Peacock Mantis Shrimp
The peacock mantis shrimp is a stomatopod, a distant relative of crabs, lobsters, and shrimp. What sets it apart, however, are its stunning colors, complex vision, and incredible strength.
- Size and Appearance: Typically growing to 10–18 cm (4–7 inches), the peacock mantis shrimp is instantly recognizable by its vibrant, iridescent coloration, which includes shades of green, blue, orange, and red. Its appendages are also striking, often adorned with bright spots and accents.
- Habitat: These shrimp prefer sandy and rubble-filled areas near coral reefs, where they dig burrows to hide from predators and store food. They are commonly found in the Indo-Pacific region, including the pristine dive sites of Bohol.
- Behavior: Peacock mantis shrimp are solitary creatures that defend their territory fiercely. Their active and curious nature often makes them a highlight of a dive.
Extraordinary Vision: Seeing the World Differently
The peacock mantis shrimp is renowned for its extraordinary eyes, which are considered some of the most complex in the animal kingdom. Each of their compound eyes operates independently and can move in different directions, giving them a unique perspective of their surroundings.
- Color Detection: They can perceive 12–16 types of color receptors, compared to the three found in humans. This means they see a much broader spectrum of colors, including ultraviolet light.
- Polarized Light Detection: Peacock mantis shrimp can detect polarized light, which is invisible to the human eye. This helps them spot camouflaged prey or predators and enhances their communication with other shrimp.
- Three Focal Points: Their eyes have three focal points, meaning they can judge depth and distance with incredible accuracy. This skill is essential for their survival, particularly when hunting.
The Power of a Punch: Nature’s Most Powerful Strike
The peacock mantis shrimp is sometimes referred to as the “boxer of the sea” due to its extraordinary punching ability. Using specialized appendages known as raptorial clubs, this shrimp can deliver a punch that is both fast and powerful.
- Speed: The punch of a mantis shrimp accelerates at speeds comparable to a bullet fired from a gun, reaching 80 km/h (50 mph) in a fraction of a second.
- Force: This strike generates forces exceeding 1,500 newtons, enough to shatter the shells of prey like crabs and mollusks. In aquariums, these punches have been known to crack glass!
- Cavitation Bubbles: When the mantis shrimp strikes, it creates cavitation bubbles—tiny pockets of vapor that collapse with immense energy. This secondary effect adds to the destructive power of its punch.
These incredible adaptations make the peacock mantis shrimp one of the ocean’s most formidable predators, capable of taking down prey much larger than itself.
A Favorite Among Underwater Photographers
Thanks to its vibrant colors and curious nature, the peacock mantis shrimp is a favorite subject for underwater photographers. The best time to spot them is during the day when they emerge from their burrows to hunt or patrol their territory.
At popular dive sites near Panglao and Balicasag Island, it’s not uncommon to encounter these creatures peeking out from their homes or scuttling across the sand. Photographers are often drawn to their bold behavior, as these shrimp are not shy and may even strike a pose for the camera.
To photograph them effectively:
- Use Macro Lenses: Their small size and intricate details are best captured with a macro lens.
- Stay Patient: These shrimp can be cautious, so give them time to emerge from their burrows.
- Avoid Disturbance: Respect their space and avoid sudden movements that might stress them.
Ecological Role and Conservation
As fierce as they may seem, peacock mantis shrimp play an important role in maintaining the health of coral reef ecosystems. By preying on hard-shelled organisms, they help control populations of species that could otherwise overgraze on coral or seagrass.
However, like many marine species, they face threats from habitat destruction, pollution, and overfishing. Coral reef conservation efforts, including marine protected areas like those around Bohol, are vital for ensuring the survival of this fascinating species.
Divers can contribute to conservation by:
- Practicing buoyancy control to avoid damaging coral habitats.
- Supporting eco-friendly dive centers that promote sustainable diving practices.
- Avoiding the use of single-use plastics that contribute to marine pollution.
