The bowmouth guitarfish (Rhina ancylostoma), also known as the shark ray, is one of the ocean’s most fascinating creatures. Its name alone sparks curiosity, as this fish blends traits of both sharks and rays, making it a true marvel of marine evolution.
Found in tropical waters of the Indo-West Pacific, this critically endangered species is a symbol of biodiversity worth fighting for. Let’s dive deeper to discover what makes this fish so special.
What Does a Bowmouth Guitarfish Look Like?
At first glance, the bowmouth guitarfish looks like a creature straight out of a sci-fi movie.
It has the flattened body and wing-like pectoral fins of a ray but sports a shark-like dorsal fin and tail. Its broad, rounded snout resembles a guitar head, hence its name. Adults can grow up to 2.7 meters (nearly 9 feet) and weigh over 135 kilograms (300 pounds), making them one of the larger species of rays.
What’s more, their unique coloration is a spectacle: a dark gray or brown body with white spots and ridges that add texture. These patterns serve as camouflage, blending with sandy and coral seabeds to evade predators.
Where Can You Find Bowmouth Guitarfish?
Bowmouth guitarfish inhabit the warm waters of the Indo-West Pacific, ranging from the Red Sea to Japan, Indonesia, Australia and our beloved Mozambique. They are typically found near sandy or muddy bottoms of coral reefs and lagoons at depths between 3 to 70 meters (10 to 230 feet). Some known hotspots for spotting them include:
The Great Barrier Reef, Australia
Similan Islands, Thailand
Tubbataha Reefs, Philippines
Mafia Island, Tanzania
Tofo Beach, Mozambique *
*Mozambique’s waters are a hidden gem for marine enthusiasts, offering a chance to encounter some of the world’s most fascinating and rare marine life, including the bowmouth guitarfish. While sightings are less documented here compared to other parts of its range,
Mozambique’s pristine coral reefs and sandy seabeds provide an ideal habitat for this unique species. For divers and nature lovers, the country's coastal hotspots, like Tofo and the Quirimbas Archipelago, could be your gateway to observing the bowmouth guitarfish up close in its natural environment. By visiting Mozambique, you’re not only immersing yourself in its breathtaking underwater world but also contributing to eco-tourism efforts that support the conservation of such endangered species.

Fun Facts About the Bowmouth Guitarfish
A Gentle Giant: Despite their intimidating size, bowmouth guitarfish are shy and non-aggressive. They pose no threat to humans and often flee from divers.
Omnivorous Eaters: Their diet is as diverse as their appearance! Bowmouth guitarfish use their flattened teeth to crush hard-shelled prey like crabs and lobsters, as well as small fish and mollusks.
"Denticles" for Armor: Their bodies are covered in dermal denticles, tiny tooth-like structures that provide armor-like protection. These ridges also add to their prehistoric look.
Mating Mysteries: Little is known about their mating habits, but they are ovoviviparous, meaning embryos develop inside eggs that hatch within the mother’s body.
Nicknamed the "Bowhead": The bowmouth guitarfish gets its nickname not just from its shape but from its snout, which resembles a bow in archery.
Why Are Bowmouth Guitarfish Endangered?
The bowmouth guitarfish is classified as Critically Endangered by the IUCN. Its biggest threats include:
Overfishing: It is targeted for its fins, which are among the most expensive in the shark fin trade, and for its meat.
Bycatch: Often caught unintentionally in fishing nets, the species struggles to survive human encroachment on its habitats.
Habitat Destruction: Coral reef degradation and coastal development pose additional challenges.
Experts estimate that their population has declined by over 80% in recent decades, making conservation efforts more urgent than ever.
How Can You Help?
Protecting the bowmouth guitarfish requires collective action. Here’s how you can contribute:
Support Marine Conservation Organizations: Groups like the Shark Trust, Wildlife Conservation Society (WCS), and Ocean Conservancy actively work to protect endangered species and their habitats.
Advocate for Sustainable Seafood: Avoid consuming seafood from unsustainable fisheries, as bycatch significantly impacts guitarfish populations.
Spread Awareness: Educate others about the importance of preserving marine ecosystems and share stories of endangered species like the bowmouth guitarfish.
Visit Ethical Aquariums (if you must): Facilities that emphasize conservation, like SEA LIFE Sydney Aquarium, provide educational opportunities and fund research.
Reduce Ocean Pollution: Simple acts like using reusable bags and bottles can minimize plastic waste, which damages marine ecosystems.
