What is the difference between freshwater and marine sponges. Why is there no terrestrial sponge?
JaymeeAlyssad
Freshwater sponges are delicate in structure, growing as encrusting or branching masses. They usually appear greenish because of the algae that live on them. Freshwater sponges may attain a volume of more than 2,500 cubic centimeters (150 cubic inches).
Marine sponges are natural bath sponges (with living cells removed) that we all are familiar with. They actually are the oldest and simplest animals that have been living on earth for millions of years. Marine sponges are filter-feeding animals because all adult sponges are sessile and can't move around benthic surface. Marine sponges have no true tissues or organs, just constructed with layers of cells even without nervous system. Marine sponges come in different but striking colors, bright red, purple, yellow, and brown, etc. These colors and some are toxic as well may help them defend from sponge eating invertebrates and some fishes. Some other small marine organisms, fishes, and microscopic organisms often call marine sponges their homes.
There are no terrestrial sponges because they are filter feeders obtain from water particles.

What organisms are found in porifera?
Porifera are sea sponges. They have no symmetry (asymmetrical) and they are one of the most basic forms of life. They have a 2 cell layer wall made of collar cells, spicules, amoeba like cells, and a layer of epidermal like cells. The spicules and the amoeba like cells are in between the layer of collar cells and epidermal cells. Sponges also have pores throughout their structure. Porifera include freshwater sponges as well of marine varieties. Freshwater sponges are common although not obvious. Frequently they are green in color due to included algae.
