What do torpedo rays eat?
Atlantic torpedo ray may reach 90 kg (200 lbs.) Depending on the species, electric rays may eat fishes, worms, and crustaceans. Adult Atlantic rays consume eels, flounders, and small sharks.
How does the torpedo ray defend itself?
It uses the two kidney-shaped electric organs on the sides of its head for hunting and defense, and it has been known to take an aggressive stance to humans so it should be treated with caution.
What do marbled electric rays eat?
Small, benthic bony fishes constitute over 90% of the marbled electric ray’s diet by weight; these include gobies, hake, sea bass, mullets, jack mackerel, sea breams, goatfish, damselfish, wrasses, conger eels, and flatfish.
How does a torpedo ray produce electricity?
The rays and eel produce electricity in different ways. Rays produce electricity through modified muscle cells called electrocytes. Like a row of batteries, stimulated electrocytes move electrically charged atoms (ions) across the cell membrane, creating a combined electric discharge.
Is torpedo a cartilaginous fish?
Complete answer: > Torpedo is a marine cartilaginous fish, which produces an 8-220 volt electric charge or current depending on some species. It is a kind of bottom-living marine fish, discharging electricity which is sufficient to stun prey like small fishes, etc.
How do marble rays find prey buried in the sand?
In rocky reefs and seagrass beds, the marbled electric ray buries itself in muddy bottoms during the daylight hours. Oftentimes, only the ray’s eyes are visible above the sand. Then, the ray jumps on prey while emitting electrical shocks to stun it.
Can Stingrays electrocute you?
It’s possible for the heart to stop or for the body to go into shock after a stingray sting. Some people have died as a result of stings in their chests and abdomens. If you have a puncture wound and aren’t up to date on your tetanus booster, it’s time to get it renewed.
Who made the use of the torpedo fish concept to define electric charges?
In 1773, the eminent physician John Hunter (1728–1793) provided the best verbal and pictorial description of the torpedo’s electrical organs to date (Fig. 1).
What do electric rays eat in the ocean?
Electric rays are found from shallow coastal waters down to at least 1,000 m (3,300 ft) deep. They are sluggish and slow-moving, propelling themselves with their tails, not by using their pectoral fins as other rays do. They feed on invertebrates and small fish.
What are the Predators of an electric ray?
This ray has few natural predators due to its formidable electric capabilities and large size. Predators such as sharks and other large carnivorous fishes seldom confront electric rays. Parasites of the Atlantic torpedo include the monogenean Amphibdella flavolineata.
What do electric rays do during the day?
Most electric rays bury themselves under sand during the day and come out at night to feed. If prey is encountered, the ray will stun the creature with electricity. Then, the ray will guide the food with its pectoral fins to its mouth, which is located under its body.
What does the marbled electric ray eat?
Prey items of the marbled electric ray include small fishes such as gobies, mullet, mackerel, bogue, pandora, and damselfish among many others. It is also known to feed on benthic invertebrates.
