Sponges are very abundant of tropical waters and one of the best examples of sponges is corals which are an important factor in the formation of calcareous deposits. But still sponges are more than colonies of independent cells. Sclerospongiae (Boring Sponges): A small group of tropical sponges with siliceous spicules and spongin fibres but encased within a solid external skeleton of calcium carbonate. Cnidarians: Jellyfish is an example. Hartman and Goreau (1970) created a 4 th class Sclerospongiae for some coralline sponges collected from caves and tunnels of coral … Simple structure.

Porifera are characterized by being marine organisms with very simple taxonomic organization, so much that they do not have respiratory, circulatory and digestive systems.Their body is formed externally by pores that allow the absorption from the flow of water, a process by which it achieves its breathing, feeding, and reproduction. Sponges are the most primitive type of animal in existence, featuring a cell-based organization where different cells have different tasks, but do not form tissues. Welcome to the Marine Species Identification Portal!. The radial canal is made up of flagellated cells. Sponges are mostly solid and simple rounded cushion-like flattened in shape usually without branches. Abrasive sponges can be cellulose sponges with an extra abrasive material attached or just a thin sheet of abrasive material. Corals, Anemones, & Jellies Their structure is composed of simple aggregations of cells. Examples of Platyhelminthes invertebrates: a) Taenia solium.

However, sponges exhibit a range of diversity in body forms, including variations in the size of the spongocoel, the number of osculi, and where the cells that filter food from the water are located. Canal system is leuconoid type. Scottish Anatomist and Zoologist Robert Edmond Grant proposed the name Porifera (L. Porus, pore and ferre, to bear). However, sponges exhibit a diversity of body forms, which vary in the size and branching of the spongocoel, the number of osculi, and where the cells that filter food from the water are located. Porifera is a Latin word (Pore - Porous and Ferra - bear ) used for a group of animals having a lot of minute pores, through which water enter, circulate and leave the body. The tissue of sponges encloses a vast network of chambers and … Although they have specialized cells for particular functions, they lack true tissues in which specialized cells are organized into functional groups. c) Wuchereria bancrofti.
