If you mean Nematocyst, a structure such as jellyfish
No. A vertebrate has a bone structure.

Jellyfish do not have a skeletal bone structure, which is essential in mammals.
An invertebrate can be anything from a worm to a jellyfish(no bones or skeletor structure)
When you are talking about jelly under the ocean, you usually mean jellyfish. And jellyfish, like any other living organism, do have structures. They don't have skeletons, but they do have organized tissue.
Jellies, like Congress, are a spineless collection of free-floating blobs with no discernible leadership capability.
A cnidoblast is the harpoon like structure of a jellyfish and a nematocyst is the stinging cell
Jellyfish reproduction involves several different stages. In the adult, or medusa, stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs into the water, forming a planula. In this larval stage of jellyfish life, the planula hooks on to the bottom of a smooth rock or other structure and grows into another stage of jellyfish life, the polyp--which resembles a miniature sea anemone. During this stage, which can last for several months or years, asexual reproduction occurs. The polyps clone themselves and bud, or strobilate, into another stage of jellyfish life, called ephyra. It is this form that grows into the adult medusa jellyfish.
A jellyfish takes food in through its mouth which is located on the underside if its bell. Food is digested in a sac-like structure called a coelenteron or gastrovascular cavity. Waste material is passed out through the mouth.
The jellyfish live in jellyfish fields.
Yes, the box jellyfish IS a true jellyfish.
