Porifera (Sponges)
Sponges are very diverse invertebrates that live under the sea. They come in a large variety of colors, shapes and structural complexities.

What are the pores of a sponge called?
Small pores of sponges are called ostia through which water enters while a large pore through which water exits is called osculum .
The use of marine sponges as bioindicators of water contamination is well established due to their simple body structure, filter-feeding life style and widespread abundance. Sponges are unique among marine invertebrates in that they have no internal organs specifically designed for filtering large volumes of water. When the water around them is badly polluted, the sponges die and can be an indication to the human population in the area that soemthing is wrong. Also,as living organisms (even the most primitive, as they are), they are part of the food chain and this by definition serve some other organisms as food; sea sponges serve as the primary food source for endangered hawksbill sea turtles.
Do porifera have digestive cavity or digestive tract?
Sponges have flagellated cells over the surface of their bodies, these are cells that have tails that wiggles. The collective effort of all these cells creates a water current through the many porous openings in the sponges body. It is a water based circulatory system.
What are the genus and species of a sponge?
The genus species of an animal is their scientific name. humans scientific name is "homo sapein". therefore, our genus is "homo" and our species is "sapein". so find out its scientific name, and you'll have the answer.
How do Phylum Porifera get feed?
They filter feed on bacteria, protozoans, unicellular algae, and bits of organic matter.
Many sea sponges, like anemones, use toxins to repel would-be predators. Some species of sea slugs, however, such as Platydoris scabra, have evolved immunity against the toxins of specific sponge families (in this case, Microcionidae). This adaptation benefits the slugs in two ways. First, they don't have to compete with many other organisms for the sponges. The sea slugs can also concentrate the sponge toxins to foil their own predators -- at least until the slugs' predators also evolve immunity to the toxins.
Why is water movement through sponge body important for feeding?
Sponges are animals and are heterotrophs- they need to take in nutrients and food for energy. The nutrients are carried by the water into the sponge.
its because the gemmules are like the little packages that hold the start of another sponge, so even if the sponge doesnt survive, the gemmule will, and then when conditions get better the gemmule will make another sponge.
What is the charateristic of sponges filter microscopic organisms from the water for food?
trhe water is really good for pepple that are really good with you and your friends
How do sponges obtain their food and water?
They filter feed.
This means that water flows through the pores in their bodies and special cells with hairs strain the water and keep tiny food particles for the sponge to digest.
A simple, but effective form of filtration. A current of air is passed through the center of a sponge such that as the air rises, it draws water into the sponge, thereby filtering the water. Sponge filters are very easy to clean (rinse and squeeze in water) and last years. Plus, baby fish don't get trapped in them like so many other filters. There are several styles of sponge filters ranging from square sponges to long cylinders to tall cylinders.
Yes , but they mostly die of people pulling them out of the water which is where they get their oxygen. When sea sponges are born they move through the water until they find a spot then they stay there for years if someone pulls them out of their spot or out of the water then they instantly die.
well they need water but nothing much. you can get one at pets mart
What is the feeding pattern of sponges?
Sponges are sessile organisms during their adulthood, meaning they do not move. To feed, sponges have adapted a process known as "filter-feeding." Basically, small particles of food passing by in the water are taken in by the sponge and digested directly in the sponge's cell layers. The larvae also feed this way, although they are not sessile and are free swimming.
How long can a sea sponge live out of water?
as long as there is no predators and enough stuff to sustain life.
Some examples of sponges are: Sea Sponge,Tube Sponge,Vase Sponge, Yellow Sponge , Painted Tunicate Sponge, and the Bright Red Tree Sponge.
Please note that Coral and Sponges have a lot in common but are not the same.Corals are related to Jellyfish and Sea Anemones and are far more complex than sponges.
What is a bath sponge made from?
Sponge is made of air and solid materials which have been washed together.
What colors can a sea sponge be?
the colors a sea urchin could be is black olive brown purple blue and red
What are the classes of phylum porifera and examples?
There are four classes in the phylum porifera. The following are the classes with example.
- Calcarea. E.g - Clathrina clathrus
- Hexactinellida. E.g - Venus flower basket.
- Demospongiae E.g - Red encrusting sponge.
- Homoscleromorpha E.g - Oscarella lobularis
Why doesn' the sponge need symmetry?
No one organism really needs symmetry. When you think of symmetry though, you usually think of bilateral symmetry. This is when two sides of an organism are almost identical. The sponge just grows whichever way it pleases.
What is the evolution of the sponge?
The sponge is a niche filler. It is a simple filter feeder which is hard to replace with any other animal because of it's simple life cycle.
