The scientific name Porifera is a neuter plural of the Modern Latin term porifer, which comes from the roots porus meaning "pore, opening", and -fer meaning "bearing or carrying". Overview Sponge biodiversity and morphotypes at the lip of a wall site in 60 feet (20 m) of water.
While also known as the "boring sponge", Cliona celata is the only species of sponge without microscleres. [citation needed] Cliona celata is a distinctive sponge known for its unique morphology and characteristics. In its 'raphyrus' or massive stage, it forms large lobose structures with rounded ridges, reaching sizes of up to 40 cm across and ...
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include greater than 90% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). [5] They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite [citation ...
Spongilla lacustris is part of the class demosponges of the phylum Porifera. The Porifera phylum contains all sponges which are characterized by the small pores on the outer layer, which take in water. The cells in the sponge walls filter food from the water. Whatever is not uptaken by the sponge is pumped through the body out of a large opening.
Techniques such as the rope and mesh bag method are used to culture sponges independently or within an integrated multi-trophic aquaculture system setting. One of the only true sustainable sea sponges cultivated in the world occur in the region of Micronesia , with a number of growing and production methods used to ensure and maintain the ...
This would also render Porifera (the sponge phylum) paraphyletic. Borchiellini et al. (2001) argued that calcareans were more closely related to Eumetazoa (non-sponge animals) than to other sponges. [9] A few studies have also supported a sister group relationship between calcareans and Ctenophora (comb jellies). Many authors have strongly ...
The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five infrakingdoms / superphyla , namely Porifera , Ctenophora , Placozoa , Cnidaria and Bilateria .
As said in the introduction, little is known about reproduction. Sperm was found in one sample of E. aspergillum, within the connective tissue, and was described as aggregated clusters within very fine, thread-like appendages. [9] This would contribute to the idea of the species being hermaphroditic.
