Sponges (Porifera) are a group of animals that includes about 10,000 living species. Some have feet so that they can walk or run; others slither along on the ground. Sponges were first to branch off the evolutionary tree from the common ancestor of all animals, making them the sister group of all other animals. To the naked eye, deep-sea sponges seem to sit totally still, confined to one spot on the ocean floor. Development 4. Sponges move so slow that they cannot avoid being eaten. Sponges also have profound regeneration capabilities, so small pieces may develop into fully grown clones of the original if they are broken off from the original. As members of the Animalia kingdom, sponges are technically animals. They are "sessile" animals (they don't move around) and they live by pumping large volumes of water through their bodies and filtering out tiny organisms and organic particles as food. Demosponge, calcareous, glass sponges. The sperm is released into the water column by the \"male\" sponge and finds its way to the \"female\" sponges, where fertilization occurs internally. The packaged sponges are boxed, and the boxes sent to a warehouse for further distribution. In sexual reproduction, a sponge releases eggs into the water where they float until captured by another sponge that fertilizes them. sessile - permanently attached to a substrate and unable to move on its own.

They are vulnerable to any organisms that can overcome their defenses and are prey to many species of turtles, fish and invertebrates. 3) Early scientists classified sponges as plants. Spicules form the "skeleton" of many sponges. Asexual methods of reproduction include: the growth of stolons that develop into new individuals; a bud separating from the parent sponge and creating a new sponge elsewhere; and the simple act of parts of a sponge breaking of and establishing in a new location.

A sponge is a block that can be used to remove water around itself when placed, turning into a wet sponge in the process. The shapes of their bodies are adapted for maximal efficiency of water flow through the central cavity, where nutrients are deposited, and leaves through a hole called the osculum. Sponges do not have nervous, digestive or circulatory systems. Motile lava.
