Limestones are a class of the phylum Porifera. They are the only sponges whose mineral skeleton is composed of spicules of calcium carbonate. They are believed to be the most primitive group of sponges. Wikipedia
Scientific name: Calcarea
Category: Class
Top rating: Porifera

# data[].attributes.body
The name Porifera comes from the Latin word meaning 'pore bearer.' This is an highly accurate name, because all animals of this phylum have bodies covered in tiny pores that work in one way or another regulate most aspects of their lives

Sponges have special cells (Unique in animal kingdom) They have flagella ,that works like a whip to make water currents , so the sponge can filtrate food particles from the water currents http://www.qm.qld.gov.au/microsites/biodiscovery/03sponges-and-corals/structure-of-sponges.html

Sponges are hermaphrodites
Each organism can act as a male or female

Mainly sponges reproduce by budding thats consist in  small lumps that grow on the surface of the parent organism .

Senses and Organs

Sponges have no nervous system or organs like most animals do. This means they don't have eyes, ears or the ability to physically feel anything

Reflex Organs

Sponges can't digest everything they find in the water, so they expel or "vomit" these inedible particles. Some researchers compare the process to sneezing

All sponges have the similar excretory system .Mainly
cells absorb the nutrients from the water and the water with no longer nutrients is expelled through a pore called osculum

Sponges dont have  a real circulatory system .

Sponges have flagellated cells over the surface of their bodys, this are cells that have tails that moves..

The collective efort of all these cells creates a water current through the main porous openings in the sponges body. It´s a water based circulatory system

Sponges breathe through the surface of their body.
They instead of having lungs like humans , they have tiny holes (Spores)  all over the body. http://study.com/academy/lesson/porifera-respiration-respiratory-system.html

Sponges do not have digestive system, but they absorb water with food particles wich special cells trap to feed the sponge

Their body usually are like a  cylender (cilindro) , but there are more types , another structure would be like an fanfield (abanico) and another one could be an straw (pajas)

They can contain 16.000 animals inside of them

They extract the nutrients from the water, concentrating as viable food.
