How do cnidarians eat?
Mainly through suspension feeding. Cnidarians use stinging tentacles (nomocytes) to capture their prey. Once the tentacles grab the food it is absorbed in the gastrovascular cavity (stomach) and taken in asnutrients.
What is one type of cell all cnidarians have?
Cnidarians all have stinging cells called nematocysts with which to catch their prey.
Who is the prey of the vampire squid?
prawns, copepods, cnidarians, and other small inverdebrates.
What structure are the stinging cells of cnidarians located?
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.
What is the effect of the poison produced by cnidarians on there prey?
The poison produced by cnidarians, such as jellyfish and anemones, acts by paralyzing or killing their prey upon contact. This poison is delivered through specialized stingers called nematocysts, which inject venom into the prey. The venom can cause pain, tissue damage, and even systemic effects in some cases.
Stinging cells in yhe tentacles or cndarians for capturing prey?
All Cnidarians have tentacles with stinging cells in their tips which are used to capture and subdue prey.
Are cnidocytes significant to fundamental processs for cnidarians?
Cnidocytes are important to cnidarians as these are the stinging cells used to catch prey and defend from enemies. It is a toxin which can disable prey and provide protection from adversaries. This can be used as a harpoon, sticky surface or lasso type action.
What is the cnidarians string cells?
They are called pneumatocysts. They are the stinging cells used for killing prey, as all cnidarians are predators. They are cells that contain poison, and have little barbs on them to inject the poison with. With some cnidarians, the little barbs are all that you feel because their poison is only strong enough to kill plankton. With other cnidarians, however, the poison in the pneumatocysts is strong and can be deadly. The main purpose of the pneumatocysts is to kill prey, but they are also useful against predators.
How do cnidarians catch there pray?
The nematocysts allow the animal to hold the prey and venom is injected. The venom is often a neurotoxin that disables the prey and prevents too much damage to the soft bodied cnidarian. There are also chemicals injected that begin the digestion process. When the prey is ingested, more digestive chemicals are used.
Extracellular digestion occurs in the gastrovascular cavity of the cnidarians when secrete chemicals to break down prey?
gland
What kind of syemmtrey is cniderians?
Cnidarians exhibit radial symmetry, which means their body parts radiate out from a central point. This symmetry allows cnidarians to capture prey efficiently from all directions.
