Porifera (Sponges)

"clean" water and "waste" water in a sponge are all the same. Their bodies allow constant flow of water, there is no beginning and end to a sponge; thus technically waste water leaves a sponges body through its many pores.

endotherm that is what they are they are so an ecdoerms ad so is any other sea animal under sea so there you go you have got your anwer and now you well know this anwer from now on right

Adult sponges, yes, are stationary. They are anchored firmly to hard surfaces - rocks or coral - and feed through siphoning water through their bodies and collecting food particles. Sponge larvae, however, are free-swimming. After they hatch, they swim and bump along the bottom until sinking and coming to a rest on a stable surface. They then anchor themselves and, over time, become an adult sponge.

"Porifera" means "to have holes". The word is Latin, since Latin is used to classify living things. It relates to the structure of a sponge because sponges have holes and openings. Think of the word "pore", which is in the word "Porifera"and is another word for "hole".

Sponges are not one sex, but rather both as needed. This is called a hermaphrodite and it allows the sponge to fertilize eggs. When the baby sponges are released through the oscula they float in the water for several days. They look like plankton, but they attach themselves to the first hard surface they find. Then, they begin growing to become adult size sponges.

^ Was a great answer but didn't really answer the question. Yes, Sponges are hermaphroditic and they contain both male and female gametes, however, as the water passes through the sponge, the sponge releases it's sperm in hopes that it would enter another sponge and then it will find it's way into the egg.

Of the choices choanocytes, medusa, spicules, or gemmules, Medusa is the option that is not associated with sponges.

Natural sponges are way more expensive. And since they grow fairly slow and have to be harvested during rather nasty working conditions(by hand, by divers) they're not the most ethical of products.

1. they communicate
2. their cells can communicate
3. hello
4. dear friend i hope some of this information is useful
5. the sponges cells can communicate with the sponge cells.
6. for an example say there is 2 sponges and one of the sponges cells communicate with the other sponge it's like talking for sponges.

is a whale shark a forager grazer filterfeeder predator scavenger and parasite

yes, some even live in the Atlantic and Indian ocean too.

The body structure of a sponge is mostly a spongy skin that is jelly like. The outer layer of this skin is bombarded with pores, which it uses to filter feed. In the filter feeding process, it eats the tiny plankton and other organisms that live under the ocean. It has a large cavity inside of the sponges skin where in reproduction, the sponge stores the sperm and egg cells to make the sponge larvae. The larvae then swims out of the sponge using its newly developed flagella and lands safely somewhere on the bottom of the ocean, where eventually, this sponge will grow to be an adult.

sponges are hermaphrodites. Sperm and ova derived from archeocytes or choanocytes which undergo gametogenesis. Cross fertilization and internal fertilization is taken place.

Porifera are sponges, they have no main organs or tissues. They are a loose aggregation of cells. To eat they pump water though their system and catch the particles in the water. A very basic cell structure.

SOAK IT IN BLEACH WATER

there are really many types of sponges. One is the octopus sponge people love this kind because it contians a lot of fluid inside it. Another type is the seahorse sponge with is huge and it can bite through a shark. it is the size of two elephants! one more sponge is the lily pad sponge it is a light green with the smell of frog on it, it doesnt smell nice and it eats dolphins which IS MEAN!

U

there are only 2 types of sponges known to man. the carboniferous and the ostrolliferous. the difference between the two is the carboniferous is made of decayed plant and animal waste.

Many Sponges have chemical defenses that protect them against certain bacterias. They make toxins which cause unpleasant tastes and odors that prevents coral overgrowth and wards off predators.

sponges have cellular level organisation meaning that their cells are specialized so that different cells perform different functions

Phylum Porifera or Sponges are the invertebrates are simple animals,live in water,cannot move from one place to another and have foul smell.

Examples are:

Sponges

Sycon

Spongilla

Euplectelea
