What type of animal uses toxins on nematocysts to capture prey?
jellyfish and mosquitoes are two creatures that have nematocust a stinging cell used by animals hunting and stunning their prey
What is a cindoblast?
It is the defensive organ present in Colenterates like Jelly fishes. If you handle these coelentrates with bare hands may even lead to death. The Cnidoblasts are also called Nematocysts or stinging cells.
What are characteristics of coelenterate?
Characteristics. All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.
How do caecilians protect themselves?
Cnidarians are unique because they contain cnidocytes when no other organism does. Cnidocytes are cells inside the epidermis of the tentacles and these cells contain organelles called cnidea. There are different types of cnidea in cnidarians such as nematocysts which contain a stinging venom to paralyze prey and spirocysts which contain sticky threads to capture prey.
What adaptations do a clown fish have for survival?
Clownfish live in symbiosis with the Sea Anemone. The Clownfish leaves waste for the Anemone to feed on while the Anemone shelters it from predators. The most predominant adaptation a Clownfish has is its ability in immunity to Anemone stings, thusly, the mutualism.
Where are nematocysts located?
Nematocysts are located within a capsule in the cell. The capsule has a lid that opens when the nematocyst is discharged.
Nematocysts are found only in what?
Nematocysts are are only found in the animal phylum Cnidaria, which includes sea anemones, corals, and jellyfish.
What phylum has nematocysts?
Phylum Cnidaria
Where are two main locations of nematocysts?
Nematocysts are found in sea creatures, specifically jellyfish and anemones. The nematocyst is an organelle found in these creatures that enables them to fire toxins. These toxin-causing nematocysts are responsible for the stinging capabilities of jellyfish, anemones, and other cnidocytes.

What is a capsule on a cnidarians tentacle called?
Nematocysts
What do jellyfish use to inject the toxin into their prey?
Nematocysts.
Explain cnidocytes their nematocysts function in food capture and defense?
As to the functions: stinging nematocysts function primarily for the capture of prey, and secondarily as a defense mechanism. There are many types of nematocysts, such as those that function to inject toxins to immobilize prey, and those which serve to entangle and hold onto the intended meal by wrapping around it. Species of cnidarian jellies vary in the types of nematocysts they possess, and this can be used to some extent in classifying and identification.
What anamiles haves pecialized stinging cells called nematocysts?
Nematocysts are specific to the phylum Cnidaria, which contains sea anemones, corals, and jellyfish, along with some less well-known animals. Nematocysts are the most common form of cnidocytes, the general term for the stinging cells all cnidarians possess.
Which two functions do nematocysts perform?
Capturing food and attachment .
What kind of substanses comes out when jellyfish sting?

Where does the sting on a jellyfish come from?
The tentacles of jellyfish contain cells called nematocysts that have tiny harpoon-like structures that shoot out when touched. The nematocysts also contain a toxin which is injected into the skin upon contact.
