Jellyfish
Found in every ocean, jellyfish are not technically "fish." Jellies have an umbrella like structure that allows them to float beautifully in the water. Watch out though, some of them sting!

Do jellyfish put their food in their mouth or drop it in their mouth?
Since jellyfish float in the water with their tentacles hanging down, you would say they put food into their mouth.
Yes actually jellyfish are descendents from the schishordizor species who have a direct line to the common centapide
Why do you think people will be stung by a dead jellyfish?
The tentacles are still partially active for some time,so the chemical is still produced for a couple hours.

What is the most common jellyfish in the Chesapeake Bay?
There are five common types of jellyfish found in the Bay and its tributaries. Of these, only three are considered true jellyfish. The other two, the mermaids purse and the sea walnut, have no or few tentacles and cannot sting. The second group, known as comb jellies, are generally transparent but often tinged green or pink and have bands of seemingly colored cilia striping their bodies. Flapping of the cilia allows the jellies to propel themselves casually through the water. The most distinctive characteristic of the sea walnut is its ability to luminesce, emitting a green glow, when disturbed. The other three types of jellyfish do not have such innocuous traits as the comb jellies. These jellyfish, the lion's mane, moon jellyfish, and sea nettle, all have tentacles loaded with stinging cells. The lion's mane floats through Bay waters only during the winter and early spring and is not a hinderance to normal recreational activities. The moon jelly is the Bay's largest species but its sting is generally mild. It is characterized by fringe-like tentacles and clover-shaped red gonads.
Name a land animal that is sessile?
Sessile means nonmotile. Animals in this category include reef-building corals, mollusks, barnacles, and sponges. On land, scale insects mature as sessile animals.
How long do jellyfish tentacles grow to?
a jellyfishes tetacles can grow to be over 150 feet long not counting the "bell" or "hood".
Which animal would be more likely to leave fossil remains a jellyfish moth or a fox explain?
No one knows!!?!?!?!?!?!?! Why do you think I am here?!?!?!?!
Which is heavier seawater or freshwater?
Salt water is heavier, as it has salt disovled in it. This can be observed in some underwater caves.
What is the jellyfish that doesnt have tentacles called?
The mushroom cap Jelly fish. Rhopilema verrilli
What is the most important body part of a jellyfish?
The visceral part, also known as the autonomic nervous system.
To what family does the jellyfish belong?
One of these:
Agalmatidae, Apolemiidae, Erennidae, Forskaliidae, Physophoridae, Pyrostephidae, Rhodaliidae, Abylidae, Clausophyidae, Diphyidae, Hippopodiidae, Prayidae, Sphaeronectidae, Physaliidae, Rhizophysidae, Olindiidae, Monobrachiidae, Microhydrulidae, Armorhydridae, Geryoniidae, Halicreatidae, Petasidae, Ptychogastriidae, Rhopalonematidae, Cuninidae, Solmarisidae, Aeginidae, Tetraplatiidae, Halammohydridae, Otohydridae, Lucernariidae, Kishinouyeidae, Lipkeidae, Kyopodiidae, Depastridae, Thaumatoscyphidae, Craterolophidae, Carybdeidae, Alatinidae, Tamoyidae, Chirodropidae, Chiropsalmidae, Atollidae, Atorellidae, Linuchidae, Nausithoidae, Paraphyllinidae, Periphyllidae, Cyaneidae, Drymonematidae, Pelagiidae, Phacellophoridae, Ulmaridae, Cassiopeidae, Catostylidae, Cepheidae, Lobonematidae, Lychnorhizidae, Mastigiidae, Rhizostomatidae, Stomolophidae, Thysanostomatidae, Versurigidae
Do the baby jellyfish look like the adults?
When they are very tiny they don't - they look more like anemones. Then they flip over and start to swim and look like very small adults.
What are uses for jellyfish parts?
Cyphozoan (a type of jellyfish) is the only jellyfish harvested for food. Also some species of jellyfish can be used in biotechnology where scientists experiment with the genes from jellyfish e.g GFP (green fluorescent protein) which can be inserted into the cells of other organisms.
What is the Portuguese-man-of-war named after?
The Portuguese Man-of-War is named after a Portuguese caravel.
------
If that is true, then why is it called a 'man of war'? The Portuguese naval fleet never had a 'man of war'. That is limited to the British Naval fleet. The Portuguese caravel was either a square-rigged sailing ship, or a tri-lateral lateen. To perceive that the Physalia physalis profile is congruent with a Portuguese sailing vessel shape is ludicrous. But then, I've been wrong before.
Is everything a jellyfish does because of instinct?
it would never get instinct because it was around for 650 millions of years.
What is the difference between Portuguese man-o-war and man-o-war?
they're the same species but it's more specific to call them portuguese.
What happens if jellyfish go extinct?
If jellyfish go extinct, it could disrupt marine ecosystems significantly, as they play a crucial role in the food web. Many species, including sea turtles and certain fish, rely on jellyfish as a food source. Their absence could lead to overpopulation of other species, resulting in imbalances in marine biodiversity. Additionally, jellyfish contribute to nutrient cycling in oceans, so their extinction could affect nutrient dynamics and overall ocean health.
Interesting facts about jelly fish?
Jellyfish are fascinating creatures that have existed for over 500 million years, making them one of the oldest living species on Earth. They possess a unique structure, lacking a brain, heart, or bones, and are primarily composed of water—about 95%. Some species can glow in the dark due to bioluminescence, and they have specialized cells called cnidocytes that contain stinging nematocysts to capture prey and defend against predators. Remarkably, certain jellyfish species, like the Turritopsis dohrnii, can revert to their juvenile form, effectively allowing them to escape death and potentially live indefinitely.
