For what do spiders use their poison?

Which group of organisms is found in oceans and use stinging cells called cnidocytes to capture prey?
Jellyfish, corals, and sea anemones are examples of organisms found in oceans that use stinging cells called cnidocytes to capture their prey. These cnidocytes contain specialized structures called nematocysts that inject toxins into their prey.
Use the word toxin in a sentence?
Lionfish are dangerous because their bodies contain a strong toxin.
What does jellyfish use to get food?
Jellyfish have cells called cnidocytes, which contain nematocysts, and located on their tentacles, mainly. Whenever a prey comes in contact with cnidocilia (structures of the cnidocytes), hundreds to thousands of cnidae (filaments of the nematocysts) are ejected into the prey 's direction; nematocysts' cnidae inoculate a poisonous or allergenic mixture into the prey 's body; the prey , if live, die by osmotic shock, paralysis or anaphylactic shock and is then brought to the mouth with tentacles or with oral arms. Jellyfish of the Order Rhizostomeae have no tentacles, instead they have cnidocytes on the manubrium (oral arms).Since jellyfish do not have eyes, they have to hunt passively. This means they just wave around their tentacles and hope for something to brush against its tentacles. When something does come in contact with its tentacles, it will fire out nematocysts and inject the prey with toxin and hope to have paralyzed or killed the prey.

What is a stinging cell cnidarian called?
A cnidocyte, cnidoblast, or nematocyte is a type of venomous cell unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.). The cnidocyte cell provides a means for them to catch prey and defend themselves from predators. A cnidocyte fires a structure that contains the toxin, from a characteristic sub-cellular organelle called a cnidocyst (also known as a cnida or nematocyst). This is responsible for the stings delivered by jellyfish.
Is it true that when venomous snakes bite their prey they can smell the venom they have injected into their prey and that is how they track them?
No, venomous snakes do not track their prey by smelling the venom they inject. Snakes use their sense of smell to locate prey, and once they bite and inject venom, the venom works to immobilize or kill the prey. Venom can also aid in digestion once the prey is consumed.
How does nematocysts work for cnidarians?
All Cnidarians have nematocysts as a specialized organelle. Cnidarians use their nematocysts to capture prey and as a defense mechanism against predators.
What kind of animal is shaped like an umbrella and has string cells?
The animal is a jellyfish. Jellyfish have umbrella-shaped bodies and possess specialized stinging cells called cnidocytes, which they use for prey capture and defense.
