Prey
a circle with strings coming off all sides
It may not be more poisonous.
No.
Well, after a female sends out a larvae it becomes a polyp. BTW that's pretty important. And after some time it becomes a medusa, AKA a jellyfish or what you are used to seeing. I hope this helped. X)
1. it's an egg 2. it cracks up 3. it looks like a letter Y and walks 4. it becomes a flat jellyfish 5. it folds up and becomes a jellfish
The tentacles surround the mouth of the sea cucumber, and are covered with a thin film of mucus. Small particls in the water stick toa the coating and covers the tentacles. When a tentcle becomes saturated, the cucumber puts it in its mouth and literally sucks off the food particles. Summary of that little paragraph: Tentacles are the first stage of the Digestive System. They grab food and put it in the mouth.
The flesh of some coral reef fish that the great barracuda eats is poisonous and so the barracuda's flesh becomes poisonous too. This may explain why barracudas in some areas are poisonous, while those from elsewhere are perfectly safe to eat.
the boxed jellyfish are little jellyfish but they can be big. there venom is the most deadly of any jellyfish and can kill an adult in about 15 or less min. to cure it you put vinegar on the stung area. Box jellyfish are in the phylum, Cnidaria. Recently scientists moved them from within the 'true jellyfish' class, Scyphozoa, into their own class, Cubozoa. Their cylindrical shaped bell is rounded at the top and becomes almost square in cross section at the margin of the bell, giving them an almost cubical, or box-like appearance. Projecting down from each corner of the bell is a short, fat appendage called a pedalium. From one to as many as fifteen tentacles are attached to each of the four pedaliums, resulting in between four and sixty tentacles per jellyfish. Only twenty species have been identified, most of them recently, because they are particularly difficult to study. They can move quickly, have complex sets of eyes (including lens, corneas, and retinas), and demonstrate in the lab the ability to avoid objects. Genetics and better science technique will probably help identify many new species, especially given their threat to an ever increasing number of humans entering the marine environment. However, not all Cubozoans are a danger to humans.

No These frogs becomes poisonous by concentrating chemicals collected from the insects they eat, so it'll take them a while to get up to strength.
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
Jellyfish have two stages to their lives. Once they have mated the fertilized eggs settle on the sea floor and develop into small, sessile, polyps. Then some time later these polyps will start budding, each bud will turn into a free swimming miniature jellyfish that becomes part of the plankton and then grows bigger to look like the adult.
