ION OF CLASSIFICATION OF NON-CHORDATES UPTO CLASSES WITH SALIENT FEATURES Vanramliana Pachhunga University College Aizawl‚ Mizoram 1. Phylum Porifera: From the Latin porus for pore and Ferre to bear‚ hence an animal with with pores. ~5000 species. Characteristic features:- a) Multicellular; no true tissue; asymmetric; sessile b) spongin- protein fibers for structure; spicules for skeleton c) filter feeders using collar cells (choanocytes) & amoebocytes

You may have learned in an earlier course that sponges are in the phylum Porifera. This group is now known to be polyphyletic‚ and all sponges belong to either phylum Calcarea or phylum Silicea. They are the simplest animals and lack true tissues. Label the following: pores‚ spongocoel‚ epidermis‚ amoebocytes‚ choanocyte‚ flagellum‚ spicules‚ epidermis‚ and mesohyl. On this

Porifera? Porifera is a phylum under the kingdom of Animalia. Porifera is the oldest phylum in this kingdom and has been around for the last 600 million years. The most common organism in this phylum is sponges. Porifera comes from the Latin words porus (pore) and ferre (bear)‚ meaning "pore-bearer". This is a reference to the numerous holes (pores) on the sponge ’s surface. Characteristics of Porifera All organisms belonging to the phylum Porifera; Have no definite symmetry Have

the Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests the ranks of Arthropod would swell to over 10 million species! Most people do not normally think of a clam‚ a jellyfish‚ or an earthworm as an animal. Yet all of them belong to the kingdom of animals. The science of classifying organisms is called taxonomy. In order to study living things‚ scientists classify each organism according to its: Kingdom Phylum Class Order Family

NEWLY DISCOVERED DEEP-SEA MARINE CARNIVOROUS SPONGE Phylum Porifera is considered as a simplest form of animal consisting of sponges. Many families under this phylum have distinctive characteristics specifically feeding processes that help them become successful in terms of adaptation and survival despite of being simple and some are smaller compared to other marine organisms. A new species of carnivorous sponge (Phylum Porifera) have been discovered in the coast of Namibia particularly in the
