The wpd, the world database of all recent sponges ever described, is part of the world register of marine species (worms), a global initiative to arrive at a register of all marine organisms.

Sponges, the members of the phylum porifera (/ p ɒ ˈ r ɪ f ər ə / meaning pore bearer), are a basal metazoa (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.

The sponges a phylum of the metazoa, comprising a group of sessile, aquatic animals possessing an endoskeleton and many branching canals, lined by flagellated collar cells communication of the canals with the surface is made through many pores or through larger openings and oscula. Poriferans are commonly referred to as sponges an early branching event in the history of animals separated the sponges from other metazoansas one would expect based on their phylogenetic position, fossil sponges are among the oldest known animal fossils, dating from the late precambrian.

Porifera life cycle the life cycle of a sponge is a relatively simple one sponges can reproduce sexually and asexually there are many sponge species in which each sponge is considered male and female. Introduction to phylum porifera the phylum porifera comprises the spongessponges are simple invertebrate animals that live in aquatic habitats although the majority of sponges are marine, some species live in freshwater lakes and streams. The body of a sponge is a collection of a few different types of cells loosely arranged in a gelatinous matrix called a 'mesohyl', mesoglea or mesenchyme.

  • In this lesson, we will explore the phylum porifera and look at the organisms that make up the group we will discuss their key features, body structure, their filtration mechanism, and why they.
  • Porifera: life history and ecology sponges come in an incredible variety of colors and an amazing array of shapes they are predominantly marine, with the notable exception of the family spongillidae, an extant group of fresh-water demosponges whose fossil record begins in the cretaceous.
