what is the arm like structures surrounding the mouth of cnidarians
Stinging cells ,tentacles .
The stinging cells of cnidarians, called cnidocytes, are located on specialized structures called nematocysts. These nematocysts are found on the tentacles of cnidarians and are used for defense and capturing prey.
Well sense your mom is sooo fat, idek . c:
Cnidarians all have stinging cells called nematocysts with which to catch their prey.

Appendages in cnidarians are called tentacles . They are used in food capture and defense . Stinging cells are present in tentacles .
Stinging cells on cnidarians are known as cnidocytes. These specialized cells contain structures called nematocysts, which can eject a toxic thread to capture prey or deter predators. This unique mechanism is a key feature of cnidarians, which include organisms such as jellyfish, corals, and sea anemones.
No, cnidarians do not have spicules. Spicules are small, needle-like structures made of calcium carbonate or silica that are found in some sponges and echinoderms for support and defense. Cnidarians, such as jellyfish and corals, have a different type of support structure called a mesoglea.

True, tentacles are a common feature among cnidarians like jellyfish and sea anemones. These structures are typically armed with stinging cells called cnidocytes, which help cnidarians capture prey and defend against predators. Tentacles are used for a variety of functions including feeding, sensing the environment, and locomotion.
The stinging cells of cnidarians, called cnidocytes, are usually located on specialized structures called tentacles. These tentacles are used by cnidarians for defense, capturing prey, and delivering venom.
