Porifera (Sponges)

In the bathroom, kitchen or utility closet - Phylum Porifera consists of sponges.

No! Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow.

tube sponges come in many natural colors such as brown, dull green and yes, yellow. secondly tube sponges reproduce by spliting their selves in half. so i guess their only family is the one sponge.

Most glass sponges can grow to about 10 feet (3 metres) in diameter and over 7 feet (2 metres) tall.

spongin!

that is a scientific name. its latin. it's scientific name is pore-bearing animals.

One's art and one's not. There's no more to it. People think Andy Warhol's 32 identical paintings of a Campbell's soup can is art but a real soup can is not.

Solution

No because it makes filter-feeding impossible for the sponges No because it makes filter-feeding impossible for the sponges

Coral is an invertebrate, because it doesn't have a spine. Vertebrates do have spines. Invertebrates would be animals such as snails, worms, and sponges. Vertebrates would be animals such as monkeys, elephants, and anything else you can think of that has a spine.

You couldn't have picked an animal with a smaller brain, or nerve network, or nerves what-so-ever.

Sponges absorb their food by their little holes in the sponge.

Because most adult sponges can't travel in search of food they get their food by a process called filter feeding. Filter feeding is a method in which an organism feeds by filtering small particles of food from water that passes by or through some part of the organism.

Some characteristics of sponges are that they are invertebrate animals. They normally are asymmetrical. They never have tissues or organs. They feed through filter feeding. They reproduce asexually and sexually.

Sponges are heterotrophic, which is a characteristic of an animal and not a plant. Sponges are also multicellular, are made up from cells without cell walls, characteristics of the kingdom Animalia and NOT Plante.

Tube Sponges are in the Class: Demospongiae, subordinate to the Phylum: Porifera.

Sponges are not like fish,but I think that they have most of the same requirements as them.Sponges are living organisms so they need things for them to survive.Water is one of them,so if they are out of the water too long eventually they will dry out.I'm not sure what sponges eat or if they eat anything at all.Now that you mention it,I am going to have to look that up.If you have seen SpongeBob the movie,in one part of the movie this scubadiver puts SpongeBob under a bright light to dry him out,and he's a sponge.It doesn't sound scientific but it could be based on true science,but I doubt it.

Well if you are talking about a sponges life classification then it would be benthos, but if you are talking about the ocean zone then i don't know, i was trying to find that too, I know it's in my science book, but I left mine at school.

Because they don't perform photosynthesis, they are actually tiny animals!

Half of the sea sponges in the world eat bacteria by sucking it in through a hole in an appendage, but the other half uses photosythesizes a microorganisms known as endosymbionts, this alliance often produce more food and oxygen than they consume.

the only way they can move is by the water movement moving it around. It can not move by itself

They look like fully red, raised bumps. In some people, large swelling can occur around the bite as well.

Sponges are animals because they are in the phylum poridfera, which is an animal phylum, they can reproduce asexualy and sexually, and when they reproduce sexually, they use sperm and eggs instead of using other stuff that plants and fungi use to reproduce. A sponge are also a consumer, that means it eats other things, they eat almost like oysters, they filter the little organisms in water through collar cells that traps the little organism, the collar cells have whiplike structures that beat back and forth, that's how they trap food. They also have pores, all sponges have pores, it's very obvious that they have pores, and i dont think plant, bacter, fungi, or protist have pore.

Fossil records clearly show cubozoans dating back to about 350 million years ago. Most scientists think that cnidarians showed up perhaps 700 million years ago since their gelatinous bodies don't lend themselves well to fossilization. That is quite an ancient history for an animal that has the most complicated and sophisticated single cell now in existence, the nematocyte. That cell defines the phylum and can explosively launch a tubule in less than 3ms at an acceleration of about 40,000 times that of gravity, some of which can penetrate almost a millimeter (hundreds of times the length of the nematocyte).

Sponges are unusual in several ways, one being that they have almost no "normal" organs. Also, sponges do not have mouths but feed by filtering water through the openings in their bodies. Some sponges also have amazing regenerative properties and small pieces of sponge can regrow into another complete sponge.
