What do cnidarians protect themselves with?

What do cnidarians protect themselves with?

Cnidarians defend themselves and catch prey using their tentacles, which have cells called cnidocytes at their tips.

What specialized stinging cells do cnidarians use for protection?

Jellyfish, sea anemones, corals and their relatives in the phylum Cnidaria capture food with special stinging cells called cnidocytes, which line their tentacles.

What do the cnidarians have to protect them from predators?

The nematocysts of cnidarians restrict potential predators to a limited array of specialists. Nematocysts also allow cnidarians to prey on a variety of would-be competitors for space and food. Most species that are capable of monopolizing space reproduce predominantly asexually.

What do cnidarians use for protection and to catch food?

All cnidarians possess stinging cells called nematocysts, which can be used for both protection and helping them to catch food.

What do cnidarians use for protection?

Cnidarians are diploblastic, have organized tissue, undergo extracellular digestion, and use cnidocytes for protection and to capture prey.

What do cnidarians use for defense or capturing prey?

Cnidarians contain specialized cells known as cnidocytes (stinging cells), which contain organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, serving to immobilize prey with toxins contained within the cells. Nematocysts contain coiled threads that may bear barbs.

How do cnidarians protect themselves and obtain food?

All cnidarians possess stinging cells called nematocysts, which can be used for both protection and helping them to catch food.

How do cnidarians protect themselves from predators and other organisms?

The nematocysts of cnidarians restrict potential predators to a limited array of specialists. Nematocysts also allow cnidarians to prey on a variety of would-be competitors for space and food. Most species that are capable of monopolizing space reproduce predominantly asexually.

What special cells do cnidarians use for protection?

Cnidarians contain specialized cells known as cnidocytes (stinging cells), which contain organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, serving to immobilize prey with toxins contained within the cells. Nematocysts contain coiled threads that may bear barbs.

What do cnidarians use their stinging cells for?

capture and subdue prey

What are the stinging cells used by cnidarians to sting their prey?

Nematocysts are thread-like capsules secreted by stinging cells that are mechanically or chemically discharged through a highly pressurized mechanism, releasing venom. Stinging cells come in over thirty different morphological types, but the nomenclature varies and new definitions are emerging all the time.

How do cnidarians protect themselves from predators?

Cnidarians defend themselves and catch prey using their tentacles, which have cells called cnidocytes at their tips.

What do all cnidarians have that help them capture prey and defend themselves?

Cnidarians are diploblastic, have organized tissue, undergo extracellular digestion, and use cnidocytes for protection and to capture prey.

Why are cnidarians predators?

All Cnidarians have tentacles with stinging cells in their tips which are used to capture and subdue prey.

How do cnidarians catch their food?

Cnidarians are diploblastic, have organized tissue, undergo extracellular digestion, and use cnidocytes for protection and to capture prey.

What do cnidarians use for defense and capturing prey?

All cnidarians are carnivores. Most use their cnidae and associated toxin to capture food, although none is known actually to pursue prey. Sessile polyps depend for food on organisms that come into contact with their tentacles.

What do cnidarians use for defense?

The animals of the phylum Cnidaria show the presence of stinging cells called the cnidocytes. These cells have nematocysts that release the toxin when they catch the prey or when something touches their body. So these are both defensive and offensive cells.

What do cnidarians use to support their body?

All cnidarians possess stinging cells called nematocysts, which can be used for both protection and helping them to catch food.

What cells do cnidarians use to capture prey?

The animals of the phylum Cnidaria show the presence of stinging cells called the cnidocytes. These cells have nematocysts that release the toxin when they catch the prey or when something touches their body. So these are both defensive and offensive cells.

How do cnidarians capture their food?

Nearly all (about 99 percent) cnidarians are marine species. Cnidarians contain specialized cells known as cnidocytes (stinging cells) containing organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, and serve to immobilize prey with toxins contained within the cells.

How do cnidarians obtain their food?

All cnidarians are carnivorous predators. Jellyfish capture small drifting animals with their stinging cnidocyte-filled tentacles. Even the sessile coral polyps and sea anemones are predators ready to sting prey, grasp it in their tentacles, and push it into their mouth.

How do cnidarians protect themselves?

Cnidarians defend themselves and catch prey using their tentacles, which have cells called cnidocytes at their tips.

What cells do cnidarians use for protection?
