The phylum ____ have rings of cilia around the mouth. The phylum contains about 7000 living species, making it the second-largest grouping of deuterostomes (a superphylum), after the chordates (which include the vertebrates, such as birds, fishes, mammals, and reptiles). Echinoderms are also the largest phylum that has no freshwater or terrestrial (land-based) representatives. A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes.In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Phylum Platyhelminthes - flatworms. Unsegmented worms with thin flat bodies. Majority of species are parasitic (flukes and tapeworms). Most free-living flatworms are small and inconspicuous, but a few local species are larger, often with striking markings. Flatworms glide about using mucus & cilia as well as muscular undulations of their bodies. Most are predators of small invertebrates; their gut has but a single opening. 5. Phylum Platyhelminthes (Approximately 6500 Known Species): Flat-worms, Flukes and Tape-worms. These are flat, un-segmented, worm-like creatures with soft and bilaterally symmetrical body. In a bilaterally symmetrical animal there is a right side and a left side, a fore end and a hind end, a dorsal or back surface and a ventral or front surface. Their body shapes are adapted for maximization of the water flow efficiency. They are sessile aquatic animals and despite the existence of species living in water, a great number remain to stay in saltwater or marine environment. 1 The sponges’ external surface remains lined within very thin flat cells referred to as pinacocytes.

Acoelomates commonly possess a simple digestive tract, nervous system, and ... Because of their flat, thin bodies, many flatworms do not need a circulatory system - they use simple diffusion. Habitat Turbellaria are found in the oceans, in fresh water, and in moist terrestrial habitats. There are following characteristics of the phylum Porifera: Their bodies consist of loosely organized cells. They vary in size from less than a centimeter to a mass that can fill your arm. They are asymmetrical or radially symmetrical. Rough or spiny skin; Water vascular system; Radial symmetry and endoskeleton As such, they are very thin, or flat, so that each cell can respire (breathe) individually with the outside environment. Thus, they are flatworms! Flatworms, like humans, exhibit bilateral symmetry. 6) Dorsoventral flat with small tentacles or AURICLES on the head. 7) Dark colour but the marine ones are bright. B. Trematodes (Flukes) Endoparasitic (most) & have 2 or 3 hosts in life cycle. Cavity in the holdfast organs. Dorsoventral flat bodies I. Digeneans 1) Flukes with 2 or 3 hosts, the first a mollusc & the last a vertebrate. Answer (1 of 9): This is a phylum of invertebrates. Its members are tripoblastic animals because their body is composed of three layers of cells. An outer ectoderm layer, a middle mesoderm layer and an inner endoderm layer. They are also known as flat worms because their bodies are thin, flattened and tape like.
