What would you like to do?
they gulp lantern fishes and come to the surface at night to eat jelly fish and anchovies.
no they don't
no it doesn't. just some squishy electrical crap...
Individual Jellyfish are either male or female. The eggs and sperm develop in special areas called Gonads inside the body wall. The gonads are frequently very colorful a…nd add greatly to the beauty of the living Jellyfish. When all of the eggs and sperm are fully developed, they are released into the stomach and then through the mouth into the sea. Some of the eggs stick to the frilly mouth lips which surround the mouth of the Jellyfish. There they are fertilized by the sperm and continue to develop. As in all many-celled animals, the microscopic fertilized eggs begin a series of cell divisions which finally result in an embryo. However, the embryo does not develop directly into a baby jellyfish, but becomes a tiny, flattened creature called a Planula.
An interesting fact about jellyfish is that some jellyfish are bigger than a human, while others are as small as a pinhead. Also, they have been on this Earth since before… dinosaurs. Another odd fact is that they have no brains.
its called jellyfish because it it lives in water so that is why it is why it is got fish in its name and then jelly because its sqiggly
many jellyfish, including the box jellyfish, are eaten by sea turtles. (some jellyfish eat one another). sea turtles are usually unaffected by even a sting as deadly as one fr…om a box jellyfish. Of course like many animals, many die from habitat lose, nets, captivity, or being fished and eaten. There for, in some ways mankind is the largest predator of theirs.
Jellyfish belong to the Class Scyphozoa, Jellyfish belong to the phylum Cnidaria, a group of animals that also includes corals, hydras, and sea anemones.
All jellyfish are embodied in the Medusozoa subphylum. Medusa is another word for jellyfish, and refers specifically to adult jellyfish.
It depends on the species of the jellyfish. Most jellyfish stings are harmless to humans and do not pose any serious health risks or threats. However it is advised… that you make yourself aware of first aid for jellyfish stings before entering jellyfish populated waters. Typical symptoms of jellyfish stings can range from a simple rash to an angry blister. Jellyfish are passionate animals that will not attack humans. However if you touch a jellyfish tentacle you will experience the stinging effects. Here's a list of some jellyfish types and their sting effects: - Blue Jellyfish Stings (Bluefire Jellyfish). These jellyfish types inhabit the Western Pacific Ocean and beaches of Japan. Physical effects: Intense pain, wheals, rashes. Progressive effects: nausea/vomiting, diarrhoea, fever, chills, swelling. Treatment: Rinse infected areas in sea water. Never rinse in fresh or drinking water. Don't rub the infected areas, never apply ice and let it cool on its own. Sometimes blue jellyfish tentacles can come off of the jellyfish and "stick" to the skin, in these cases, use tweezer-like instruments to remove the tentacle. Trying to shake, rub or flick it off will spread the poison and prolong pain. Fatal?: No. - Cannonball Jellyfish stings. Cannonball Jellyfish, despite their menacingly pirate-y name, are the most harmless jellyfish species in the ocean. They actually have a passionate-relationship with humans, much like dolphins. Scientists can't explain why. They have a stinger, but it is very rarely touched by humans, the stinger is used primarily for stunning prey. Physical effects: None Progressive effects: None. Treatment: No treatment required. Fatal?: No. - Man of War Jellyfish stings. The Man of War species are probably the most aggressive species of jellyfish, even though they very rarely attack humans on purpose. Physical effects: Extreme pain, welts, serious rash, red lesions, disruption to heartbeat rhythm, lung paralysis (if stung in close proximity to the lungs). Progressive effects: Fever, chills, swelling, difficulty breathing, allergic reaction, shock, raging fever. Treatment: Rinse affected areas in sea water first, then bathe in hot or warm water to relieve pain. Never come into contact with cold freshwater, ice or vinegar products. The stingers can still be embedded in the skin and should be removed carefully with tweezers, touching the stingers with bare hands will transfer the sting. Call emergency services immediately reporting "severe Man of War sting". Fatal?: Adults - sometimes. Children - yes. - Lion Mane Jellyfish stings. Lion Mane species are the largest discovered species of jellyfish. These jellyfish sense the environment around them by releasing chemicals into the sea. If it senses a certain danger or prey with the chemicals, a sting is emitted. Most stings from these jellyfish are accidental when the chemicals come into contact with human skin. The toxicity of their sting is not very high. However because they have eight clusters of stingers, the sting can be intensified. Physical effects: Minor burns, minor blisters, varying pain depending on how many tentacles the human came into contact with. Because these species are so large, sometimes parts of their body do "fall off". If a cluster of tentacles "falls off" of this jellyfish and get caught around a human accidentally, it can cause respiration difficulty and disruption of the heart rhythm. Progressive effects: Burning sensation, nausea. Treatment: Minor - bathe in seawater. Avoid freshwater and ice. Major - same as Man of War. Fatal?: Only if the human comes into contact with a whole cluster of venomous tentacles. - Irukandji Jellyfish stings. Found in waters mainly bordering Northern Australia and the Great Barrier Reef. Most of the time, humans will not realise they have been stung by these species until a few (10-30) minutes after the sting. Despite being small jellyfish, the sting can be very venomous. If you do notice the sting, it will, at first, feel like a mosquito bite for the first 10-30 minutes. Symptoms can last 14 days. Physical effects: Muscle pain mostly around the back, abdomen and chest. Progressive effects: Headaches, high blood pressure, sweating, nausea, increased heart rate, fluids accumulating in the lungs. Treatment: Pour vinegar on the sting to neutralise stinger cells. Because of the prolonged pain period of 14 days, may sometimes need to be hospitalised and administered magnesium sulfate medication. Fatal?: Only in people with current medical conditions. Can also be fatal if the symptoms are not treated. Always see a medical professional. This is, of course, not the complete list of jellyfish sting effects. There are over 200 species of jellyfish known to man, each one have their own unique effects, but all jellyfish share at least one or two common effects. If you ever experience a jellyfish sting, try to remember what the jellyfish looks like, just so you can describe it if you need to. Just like you would as if it was a spider or snake bite. Always report your sting to a medical professional, emergency services or lifeguard. Not all stings are fatal, but some do require medical attention for the symptoms or pain relief.
NO, they have those long things called...tentacles?
Of course they can- everything does eventually. The average life span for a jellyfish is about six to eight months, but can be longer or shorter depending on what breed it is/…what it eats/how well it is taken care of.
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their cube-shaped medusae. Box jellyfish most visibly differ from the Scyphozoan jellyfish in th…at they are rounded box shape, rather than domed or crown-shaped.
Jellyfish do not generate electricity. I thought jellyfish did generate elctricity when i was small because that is how cartoons depicted it. Instead, they sting and youre rea…ction would be ike you have just be electricuted. Jellyfish stings are an all-too-common health hazard for beach vacationers. While most jellyfish stings are harmless (with a few exceptions), they can be extremely painful. The stinging sensation results when stingers at the ends of the tentacles of jellyfish and other aquatic animals come into contact with human skin, usually while wading or swimming in the ocean.
Anthomedusae Leptomedusae Siphonophorae Limnomedusae Trachymedusae Narcomedusae Actinulidae Eleutherocarpida Cleistocarpida … Coronatae Semaeostomeae Rhizostomeae
As a jelly fish doesn't have a spine, a jelly fish is an invertebrate.
