Is sponge skeleton
It's unknown exactly what species of sponge Spongebob is. As he is a cartoon sponge, he isn't really any specific species. However, all sponges are part of the phylum Porifera.
Animals. The part that we think of as "sponge" is their skeleton.
Yes they are. In many videos you can see sponges.It's nothing new to see sponges n the Coral Reefs. It's just part of the Tropical Life. yes, there are sponges in the coral reefs. they are goregous and beautiful thing too. they are in existance. they are the coral reefs. corla reefs have sponges.
Sponges are classified as "animals" of the phylum Porifera. However, they have several characteristics in common with plants. Most have no specialized tissues or organs, and depend on the flow of sea water to provide oxygen and nutrients.
Sponges are part of the animal kingdom, specifically in the phylum Porifera. They are multicellular organisms that lack true tissues and organs.
Sponges are generally considered asymmetrical, meaning they do not possess any form of symmetry. However, some species exhibit a degree of radial symmetry, particularly in their body structure, but this is not consistent across all types. This lack of symmetry is part of what distinguishes sponges from more complex organisms that exhibit bilateral or radial symmetry. Overall, sponges are unique in their body plan and organization.
In a few marine species, gray cells of the sponges primitive "immune" system and can release toxins that kill all cells in the area as part of the rejection of foreign material.They also produce toxins that prevent other sessile organisms such as bryozoans or sea squirts from growing on or near them.A few species, such as the Caribbean fire sponge, cause a severe rash in humans who handle them and such toxins may protect against predators.The Caribbean chicken-liver sponge secretes toxins that kill coral polyps, allowing the sponges to grow over the coral skeletons.See: http://en.wikipedia.org/wiki/Sponge
The part of the sponge the water flows in is the hole.
Sponges are made up of two different types of organisms - one type are plantae, the other anamalia. Although it is debatable, sponges are classified as anamalia because part of them is animal.

Sponge cells, or choanocytes, are specialized cells that help in filter feeding by drawing water through the sponge's porous body. They capture food particles and facilitate gas exchange. Over time, as sponges evolve or respond to environmental changes, these cells may adapt or differentiate into other cell types, contributing to the sponge's overall growth and regeneration. In some cases, sponge cells can also undergo apoptosis or programmed cell death as part of their life cycle or in response to stress.
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.
