What are some of the distinguishing characteristics of the Phylum cnidaria?

∙ 11y ago
Cnidaria: It's pronounced like this: naɪˈdɛəriə, (the C is silent). It is a phylum with about 9 thousand species. Among them are corals, sea anemones, hydrae, jellyfish, and many others.
The characteristic that most distinguishes them, is their "cnidocytes" (whence comes the name). These are specialized, venomous cells, used to stun, capture, and hold prey.
All cnidaria are aquatic animals, and most are marine.
All are radially symmetrical and have a single orifice and body cavity that performs digestive and respiratory functions.

Some distinguishing characteristics of the Phylum Cnidaria include having specialized stinging cells called cnidocytes, a radial symmetry body plan, and a simple nerve net for coordination. They also have gastrovascular cavities for digestion and typically exist in two body forms: polyps and medusae.

∙ 12y agoWell, an example of a cnidarian would be a sponge. But, I do know they have these cells called 'collar cells' and they use those like little whips on the inside of them to keep food in them b/c they have big pores that little...food bits come in thru. They are all also filter feeders....and I think that's all I can think of right now, but....yea, theres something. Hope that helped

What are major characteristics of the phylum?
some of the major characteristics of the phylum are a shared body plan, embryonic development patterns, and specific molecular sequences.
What phylum have some free drifting medusae?
Medusae are found in the phylum Cnidaria, which includes jellyfish. Some species of jellyfish have free-drifting medusae as part of their life cycle, allowing them to move through the water and feed on plankton and other small organisms.
What are three characteristics common to all animals in the phylum?
Animals in the arthopada phylum 3 major characteristics. They have three body parts, a tougher exoskeleton, and have jointed legs.
Phylum pisces characteristics?
Phylum Pisces includes all fish species. Some common characteristics of fish include having gills for respiration, a swim bladder for buoyancy control, scales for protection, and fins for locomotion. Fish are ectothermic, meaning their body temperature varies with the environment.
What is the classification of coral?
Corals are classified as members of the phylum Cnidaria, which includes other animals such as jellyfish and sea anemones. Within the phylum Cnidaria, corals belong to the class Anthozoa. They are further divided into two subclasses: Hexacorallia (includes stony corals) and Octocorallia (includes soft corals).
What are the differences between cnidaria and other phylums?
There are A LOT of differences between the Cnidaria phylum and other phylums. 1. all species in the cnidaria phylum have nematocysts which are the things that sting prey 2. jellyfish which are in the cnidaria phylum, do not have blood because they are made up of 95% of water 3. all species of cnidaria phylum have a single opening which means they eat and poop from the same place 4. can live anywhere from the tropics, to the poles, on the surface of the water, to the depths of the seas (some even bury themselves under the ocean bed) 5. have two different "stages" - polyp and medusa - some species of the cnidaria phylum just stay at the polyp stage and never move on to the medusa stage
What makes an annelid an annelid?
Distinguishing characteristics of the phylum annelida are conspicuous metameric segmentation, they are triploblastic, coelomate, bilaterally symmetrical, tubular bodies (worms), they have a nervous system and some sense organs
Which Stinging cells are a characteristic of members of this phylum.?
the scientific phylum name is Cnidaria. this includes animals such as jellyfish, anemone, and coral. Some are medusa shaped (jellyfish) or polyp shaped (upside down jellyfish) All of them have nematocysts which is a scientific name for stinging cells. These invertebrates evolved from sponges. New characteristics include movement (sponges move but only at the larval stage) and tissues for the movement (muscle and nerve tissue). They also evolved from asymmetrical symmetry (sorry - redundant) to radial symmetry.
Classification of invertibrates?
Invertebrates have nucleated cells and are thus eukaryotes (Domain Eukarya in the Empire of Life). They are multicellular and heterotrophic and thus animalian (Kingdom Animalia). Edward O. Wilson is what one calls a 'splitter' in taxonomy and has split the animal kingdom into about 85 phyla. Most other taxonomists think there are somewhere in the thirties in the realm of 'How many phyla are there ?' Some invertebrate animal phyla are: Phylum Porifera, Phylum Cnidaria, Phylum Ctenophora, Phylum Platyhelminthes, Phylum Annelida, Phylum Mollusca, Phylum Arthropoda, Phylum Echinodermata, Phylum Hemichordata, Phylum Nematoda, Phylum Rotifera, Phylum Kinorhyncha, Phylum Nemertea, Phylum Bryozoa
Does a hydra have bilateral or radial symmetry?
The hydra has radial symmetry. The hydra belongs to the phylum Cnidaria and many immobile species in this phylum exhibit radial symmetry. Some marine animals that have bilateral symmetry are fish, sea turtles, and marine mammals.
What are the physical characteristics of Serbs?
Serbs generally have a diverse range of physical characteristics due to their mixed ethnic heritage. They can have features such as light to medium skin tone, with brown or blonde hair and a mix of eye colors. Height and build can also vary, but generally fall within the average range for Europeans.
Do Organisms of the same phylum are all very similar?
Organisms within the same phylum share certain basic characteristics, but they can vary widely in terms of size, shape, behavior, and ecological niche. While there are similarities due to shared ancestry, the diversity within a phylum can be quite large.
Give some characteristics of organism in the phylum vertebrata?
Vertebrates are characterized by having a backbone or spinal column made up of individual bones called vertebrae. They also have a well-developed brain enclosed in a skull, a closed circulatory system with a heart that pumps blood, and paired appendages such as limbs or fins. Vertebrates typically have a protective outer covering, whether it be fur, feathers, scales, or skin.
What does cnidarian mean?
Cnidiarian is the word for the phylum of jellyfish and sea anemomes. Some of the requirements to make it into the Cnidaria Phylum are possessing radial symmetry, having no nervous system or head but having a nerve net, and possessing nematocysts (which are stinging cells unique to cnidarians). Nematocysts are also called cnidea, which likely is the basis of the meaning of the name Cnidaria.
What is some unique or distinguishing characteristics about earth?
It has living organisms on it. It was water. It has a huge range of gas' and elements. Has a regular temperature of 16* (perfect for living organisms)
What are some examples of Cnidaria?
Sea anemone Jellyfish
What is the distinguishing features of the parrot?
Bright colors are some distinguishing features of the parrot.
