Is an oyster a cnidarian?
No, an oyster is not a cnidarian. Cnidarians are a phylum of marine animals that include jellyfish and corals, while oysters are mollusks belonging to the phylum Mollusca.
Are Cnidarians protists?
No, cnidarians are not protists. Cnidarians are a diverse group of animals that include jellyfish, corals, and sea anemones. Protists are a separate group of eukaryotic organisms that are not classified as animals.
Which system is more advanced in cnidarians than in porifera?
The nervous system. Cnidarians have a neural net, but porifera do not.
What are the major inverterbrate groups?
The major invertebrate groups include arthropods (insects, spiders, crustaceans), mollusks (snails, clams, squids), annelids (earthworms, leeches), cnidarians (jellyfish, corals), and echinoderms (starfish, sea urchins). These groups represent a diverse array of organisms that play important roles in ecosystems.
Are cnidarians warm-blooded?
No. Cnidarians don't even have a circulatory system.
Are insects cnidarians?
No. Insects are arthropods. Cnidarians are animals such as jellyfish and sea anemones.
Are scorpions annelids flatworms mollusks arthropods cnidarians or echinoderm?
a scorpion is a Arthropods
Which animal is not a arthopods?
Sponges, Cnidarians, Mollusks, and Echinoderms are not Arthropods.
What are the Most complex group of invertebrate?
the most complex group of invertebrate is cnidarians
Is an hydra a arthropods?
No. Arthropods are members of the phylum Arthropoda; but hydrae are members of the phylum Cnidaria. The closest to a "common" term for animals in this phylum that exists is "cnidarians".
How are cnidarians more advanced then jellyfish?
Sponges are less complex because they are just made of individual cells. There is no level of organization past cells in sponges. Cnidarians, on the other hand, have tissues, a higher level of organization. Tissues allow for some forms, like box jelly fish, to have eyes (this is just one of many advantages of tissues). Cnidarians' level of organization stops there though, they have no organs (heart, brain, etc.).
What are all of the invertibrate groups?
An invertebrate is an organism that lacks a backbone. The 6 groups of invertebrates are sponges, cnidarians, worms, mollusks, echinoderms and arthropods.
What are Common names of animals that lack cephalization?
Which of the following groups of animals lacks cephalization? Question 4 options: Arthropods Cnidarians Roundworms Annelids
Which of the following groups would an animal with an exoskeleton segmented body and jointed appendages belong to choices mollusks segmented worms cnidarians arthropods?
Athropods. Certainly!
How do you Compare and Contrast the transport system of cnidarians arthropods fish and mammals?
Cnidarians, such as jellyfish, use diffusion to transport nutrients and gases. Arthropods have an open circulatory system where blood bathes the organs directly. Fish have a closed circulatory system with a two-chambered heart, while mammals have a closed circulatory system with a four-chambered heart that efficiently circulates oxygen and nutrients to all parts of the body.
What are the kinds of vertebrates and invertebrates?
Vertebrates: # Fish # Amphibians # Reptiles # Birds # Mammals Invertebrates: # Sponges # Cnidarians (formerly called Coelenterates) # Worms # Mollusks # Arthropods (Arachnids, Crustaceans, Millipedes and Centipedes, Insects)
Why do cnidarians not need respiratory or excretory systems?
Jellyfish are, compared to mollusks, arthropods and vertebrates, very simple organisms. Jellyfish did not evolve a respiratory or an excretory system, as they can perform gas exchange at their outer surfaces.
