any invertebrate animal of the phylum Coelenterata, including the hydras, jellyfishes, sea anemones, and corals, characterized by a single internal cavity serving for digestion, excretion, and other functions and having tentacles on the oral end. Compare cnidarian.
Is coelom present in Coelenterata?
All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.
Where are Coelenterata found in the animal kingdom?
Phylum Coelenterata belongs to the Animal kingdom found usually attached to the rocks at the bottom of the sea. They are multicellular and can be found in colonies or solitarily. These are the simplest group of invertebrate animals. These are mostly aquatic animals. The mouth is surrounded by short and thin tentacles.
What makes a Coelenterata a multicellular organism?
Coelenterates are multicellular organisms and can be found living solitarily or also in groups. They can also be found sedentary or swimming about freely. The Phylum Coelenterata consists of marine organisms that have a body that is radially symmetrical and a mouth that has sensory tentacles that help in capturing prey easily.
Which is an example of a Class 2 Coelenterata?
Anthozoa or Actinozoa belongs to Class II of the Coelenterates. These organisms have the following characteristics. These derive their name from Anthos: flower and zoios: animal. These animals exclusively belong to the marine habitat.
What does Coelenterata stand for in phylum cnideria?
Introduction to Phylum Cnideria – “Tissue grade” eumetazoans with a radial symmetry. – The term “Coelenterata” signifies the presence of a single internal cavity called coelenteron, or gastrovascular cavity, combining functions of both digestive and body cavities.
