Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Iotrochota Birotulata
''Iotrochota birotulata'', commonly known as the green finger sponge, is a species of sea sponge in the family Iotrochotidae. It is found in shallow waters in the Caribbean Sea. Description The green finger sponge usually has upright or sprawling cylindrical branches that occasionally divide. The branches are about in diameter and can grow to in length. Young individuals and some large specimens have an encrusting habit. They grow over the surface of a rock in a layer a few millimetres thick with occasional short chimney-like outgrowths. Other individuals have a number of vertical tubes, each with a large opening called an osculum at the end. These variations in growth habit led to the belief that several different species of sponge were involved. However, specimens growing in reef caves often have an encrusting base with a central, finger-like cluster of branches, so it is now believed that the different forms are a single species, perhaps differing in structure because of di ...

Poecilosclerida
Poecilosclerida is an order of the demosponge class. It is the most speciose demosponge order with over 2200 species (World Porifera Database). It contains about 25 recognised families. They are characterised by having chelae microscleres, that is, the minute spicules scattered through the tissues, usually in the 10-60  μm range, have a shovel-like structure on the end. Most of the families are viviparous with parenchymella larvae that are uniformly ciliated The cilium, plural cilia (), is a membrane-bound organelle found on most types of eukaryotic cell, and certain microorganisms known as ciliates. Cilia are absent in bacteria and archaea. The cilium has the shape of a slender threadlike projecti .... Families As of 2018, the following families are recognized: References {{demosponge-stub ...
