Each species has a distinct feature.Porifera, a Latin word that means bearing pores.Because if it's a sponge-like structure, it can absorb and hold the water for a long time.These species have a bundle of little needle-like structures called Spicules.
Freshwater sponges, as well as several marine species, form resistant structures called gemmules that can withstand adverse conditions such as drying or cold and later develop into new individuals.

They are- These sponges are found in marine forms of living shallow water in small size.
These sponges may be found from shallow to the depth of the sea in different colors with the presence of pigment granules. As these sponges are aquatic organisms, most of the species are found in Marines, some are at freshwater.some other at depth of seas.Ans. Some of the species of Porifera will eat small, tiny, floating organisms on sea level and some other species collect food from the filtered water. Basics: Phylum Porifera Traits and Classification.

The typical means of asexual reproduction is either fragmentation (where a piece of the sponge breaks off, settles on a new substrate, and develops into a new individual) or budding (a genetically identical outgrowth grows from the parent and eventually detaches or remains attached to form a colony). This means that they have many cells. PREMIUM After settling and attaching to a suitable substrate, the larvae develop into young sponges.Test your knowledge with Infoplease trivia and quizzes. Instead specialized cells carry out the physiological processes.
Asexual reproduction occurs by budding or by fragmentation. Asexual reproduction occurs by budding or by fragmentation. Pieces of sponge are able to regenerate into whole new sponges.

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.
