Fish of the Red Sea—Dangerous Red Sea Fish
With around 1,000 species of fish and 150 species of coral, the Red Sea is rich in marine life. Click on the photo for a larger view and more details about this species.
The Red Sea is famous for its rich diversity of marine life, including fish. Over 1,200 species of fish inhabit the waters of the Red Sea. Many of these fish do not exist anywhere else in the world. Among the most common species are tropical fish such as clownfish, butterflyfish, surgeonfish, lionfish, parrotfish, and scorpionfish. Other common fish in the Red Sea include perch, catfish, swordfish, bluefish, and tuna. Many of these fish are colorful and uniquely shaped, making their observation a fascinating experience for divers and snorkeling enthusiasts.
Blue-spotted Stingray (Taeniura lymma)
The Dasyatidae family includes around 100 species, one of which is the Blue-Spotted Stingray. Like all rays, they have venomous spines at the base of their tails. They breathe by drawing water through a small hole behind their eye and expelling it through gill slits on their underside. Often found lying on sandy bottoms, they rub sand over themselves to camouflage. They feed on mollusks and crabs.
Common and easy to spot in all Indian and Pacific oceans, including the Red Sea and the Great Barrier Reef. Simple to identify with their oval shape and blue spots. They are not aggressive, but if accidentally stepped on, their spine can sting a leg.
This causes intense pain, which increases over about 90 minutes and lasts, if untreated, for 1 to 2 days.
Clownfish of the Red Sea (Amphiprion bicinctus)
The most common clownfish in the Red Sea, hence its name. You will also find it in the Gulf of Aden and the Chagos Islands in the Pacific, about 3,364 km away. Interestingly, people do not find it anywhere in between
Clownfish begin life as males, but if the female dies, the dominant male transforms into a female. The Red Sea clownfish lives in shallow waters up to 30 meters deep, generally living in pairs associated with an anemone. The anemone’s tentacles protect the clownfish from predators.
On first contact with the anemone, the clownfish recoils, but gradually its mucus coating grants it immunity to the anemone’s stinging nematocysts.
Picasso Triggerfish (Rhinecanthus assasi)
People name triggerfish after their shark-fin-shaped trigger, which they use for defense.They use it to wedge themselves into coral crevices. The trigger is actually the first spine of their dorsal fin (on top). They bend the second dorsal spine forward to firmly lock the first in place.
Giant Moray Eel (Gymnothorax javanicus)
The largest of the moray eels, growing up to 3 m. Quite common and always interesting to observe. It primarily feeds on fish, occasionally crustaceans, and octopuses. Moray eels live in burrows and typically hunt at night. They can be seen rhythmically opening and closing their mouths. This action creates a respiratory current over their gills. Moray eels undergo a gender change as they grow, transitioning from male to female.
Grey Moray Eel (Sidera grisea)
The grey moray has a long body with a continuous fin along its back. Like other moray eels, it has elongated nostrils. People easily recognize it by the dashed lines that pattern its face, as shown in our photo
The grey moray is the most common eel in the Red Sea. It is relatively small for a moray, reaching up to 65 cm in length. It lives at depths of up to 40 meters on coral and rocky reefs. Groups of up to 10 young eels can often be seen sheltering in rocky crevices. The black lines on its face and body mark its pores, which are part of its lateral line system that detects pressure changes to sense movement and vibrations in the surrounding water.
Crocodile Fish (Papilloculiceps longiceps)
People primarily find the crocodile fish on sand and rubble near coral heads, though they may also find it in patches of seagrass. It stays shallow, at depths between 1 and 15 meters.
People find the head of the crocodile fish flattened, with two dorsal fins and bony crests and spines on its head. The crocodile fish, also known as the Carpet Flathead, grows up to 70 cm.
It is a very peaceful fish that relies on its camouflage to allow other fish to come close. Though related to the scorpionfish, it is harmless.
Scorpionfish (Scorpaenopsis oxycephala)
The scorpionfish is one of the most venomous fish in the world. It has several spines connected to venom glands. Its venom causes severe pain and paralysis.
The scorpionfish is extremely well camouflaged. It can change color to match its background and has many tassels that mask its outline. This scorpionfish lives at depths ranging from 1 to 35 meters in the Red Sea and the Indo-Pacific.
It lacks a swim bladder, so it stays on or near the seafloor. It waits lethargically for prey to pass by, then opens its lower jaw and sucks in its victim.
Few animals prey on the scorpionfish, as its venom acts as a deterrent. A fully grown octopus ignores the dorsal spines and envelops and eats the scorpionfish
Lionfish (Pterois miles)
The lionfish is found in the Red Sea and the Indian Ocean as far as the Andaman Sea. Elsewhere, it is replaced by the similar P. volitans. It typically has 11 dorsal spines (on the upper part of the fish).
A sting from this fish can be very painful and potentially fatal. Lionfish often shelter under rocky overhangs during the day, becoming more active at dusk and at night when they feed on fish and crustaceans. They use their non-venomous pectoral fins to herd prey into their mouths. The venomous spines of the lionfish allow it to display vivid coloration, warning predators to keep their distance.
Great Barracuda (Sphyraena barracuda)
The great barracuda is a top predator that uses its highly developed sense of smell and vision to locate prey. When attacking, it charges at high speed (approximately 12 m/s) and strikes its target.
It then unleashes the power of its jaws, allowing it to kill prey larger than itself.
Coral Grouper (Cephalopholis miniata)
The coral grouper is commonly found around coral in areas with clear water. It is easy to spot and fairly common.
It is found at depths of 2 to 150 meters and primarily feeds on fish. Juveniles have yellow bodies with blue spots, while adults grow to about 41 cm. Like all groupers, Cephalopholis miniata has a large mouth and sharp teeth. It uses grinding plates in its throat to crush prey.
Groupers are the most important family of reef predators. They are territorial and solitary, except during the breeding season in June.
They are also common in other parts of the world, including Australia.
Masked Pufferfish (Arothron diadematus)
This small pufferfish has a unique appearance, with a black mask over its eyes extending to its pectoral fins and a black mouth. It is common along the fringes of coral reefs in the Red Sea. Elsewhere, it is replaced by Arothron nigropunctatus (the black-spotted pufferfish), though some experts believe they are the same species.
They are called pufferfish because they inflate with water when threatened, making themselves appear much larger. This defense mechanism is essential as they move slowly through the water, making them easy prey for predators.
Their second line of defense is their toxicity. Pufferfish produce tetrodotoxin, one of the most lethal natural substances, through bacteria in their bodies. This toxin is up to 100 times more potent than black widow venom.
