What is the definition of a sponge?

A sponge is something that's soft, wet, and able to absorb (and maybe even expel) a great deal of liquid. I would think a sponge is not a solid because the ability to absorb is greater than the ability to hold on to it. In the same way that a cloud is not water or an apple is not a fruit because their properties are so different.

Note: I'm using the definition as given by Wikipedia: Sponges, commonly called sea sponges in reference to their aquatic. environment of origin, are a type of invertebrate that belong to the. phylum, Porifera. Also known as coelenterates, they have a coelenteron composed of a cell layer enclosing a jelly-like fluid with the ability. to contract and expand; the contraction of this allows the animal to. move through its habitat. They filter food particles from the water, either actively or passively. Sponges make up the bulk of the biodiversity of shallow seas. A sponge is not necessarily a material. For example, a human brain is not a sponge (as a brain, that is). So the proper definition of a sponge is to be a soft thing that's able to filter water.

Wikipedia gives one possible definition: "A sponge (alternatively spelled as spong) is a sessile cnidarian invertebrate with a polyp-like body plan having tentacles and no mouth, consisting of radially symmetrical tube feet which it uses to filter water for its food. It is typically a colonial organism, consisting of many interconnected individual polyps that are attached to a common base through a shared skeletal axis.

The shape of the body results in the formation of a spongy mass of interlaced cells that allows the animal to change its form, such as contracting to capture prey and expanding to create a floatation surface.

What is the purpose of a sponge?

You can tell by looking at it.

Look into a sponge and you'll see the water; look at a mirror, and you'll see yourself. But the sponge is more than water. It's a container for water; a surface that reflects water; a body that carries water; a container that collects water; a vessel that stores water; and it's an instrument that manipulates and transforms that water. A sponge is more than its capacity to store and hold liquid; it's more than the shape of its body; it's more than the substance of its surface. When we examine the sponge more closely, we'll find that the sponge is as complex as the most intricate painting. And it works just as well to absorb or carry liquids, and to manipulate them, as the most delicate and exquisite painting ever made.

A sponge absorbs water, and soaks it into the pores of its fibers; but it also holds water. In addition to storing water, it also holds it. Water in a sponge keeps water from leaking out and keeps it from running away. As you continue to examine a sponge, you'll learn that it is not just an instrument that stores, manipulates, or carries water; it's a sophisticated machine. The water in a sponge is trapped in tiny cavities that are held together by a matrix of fibers and a glue called gell. The water in a sponge is not freely flowing water, but what appears to be a liquid. If a liquid were actually free-flowing, it would have no matrix to hold it, and therefore would simply flow away. In a sense, a liquid can be contained in a sponge; it can't flow, but it can be contained.

A sponge isn't just a simple container for water. It's a container for water in a way that other containers don't have. When you watch a carpenter using a square to draw lines on a table, you know exactly what he's doing. He uses his hand to push the square back and forth over the wood, keeping it exactly centered. He's using the square like a ruler, and the wood is behaving like a piece of paper. But there's nothing that makes the square behave as a ruler; it's simply that the square is being used as a ruler. If you put the square in your pocket, you might pull it out at any time and use it as a ruler.

What are called sponges?

Are they alive, for they lack a heart?

Or they are artificial beings, for they also have heads. Their eyes look at you; they follow your arms; they touch you. They understand your thoughts. There is such a variety in the sponges that they can be divided into two species, the first which have no limbs, the second which have four. But let us examine the first sort, without the head. I have been asked to explain these creatures, and I was told that I was unable to do so. What need had they of being able to explain anything to me? The great philosophers should be asked to give us their explanations. And even if it were not so: there is no need for answer; I ask nothing but a question.

Ren Descartes, Discourse on the Two-Handed Engine, in "La guerre des mots", (The War of Words). The sponge, a marine animal, is probably the best known form of animal with a simple design. Despite its widespread distribution and great abundance, few taxonomic treatments attempt to define or classify the group. In part, this may be due to its large range of morphological variability. Moreover, the life cycles and modes of reproduction of the group may be complicated and involve more than one generation per year. Consequently, many features of the biology of sponge groups are still unknown. In some cases, as in Actinostella, there is even an intermediate stage between the juvenile and adult sponge stages (Gorochov, 2010). In another group of species, Verongiida, both the sponge larva and sponge adult stage of the polyp are hermaphroditic, in contrast to sessile representatives of the same group such as Suberites (Fauchald, 1994). This distinction has significant taxonomic and evolutionary implications (Derelle et al., 2007). Also, as is the case in many marine invertebrates, sponge species often are characterized by low genetic diversity relative to other marine species. However, there are exceptions.

What is a sponge slang?

That's what the media and law enforcement keep asking.

The real question should be: What makes a sponge? And, even better, what is it about this form of gang violence that has so many cops, politicians and academics scrambling for reasons to ban sponges?

I believe the sponge is a modern-day version of the water torture that was once used to humiliate slaves. In the 19th century, the term originated in England and, according to legend, when you were sponged by jailers, they actually filled your mouth with water then squeezed it until you lost your voice.

A sponge slang has become synonymous with gangs in much the same way. If you ever visit the streets of East Los Angeles or even more likely the suburbs of Beverly Hills, L., you will see that people have been sponged. These are usually between 20 and 25 year-olds and they are always heavily armed. No one really knows how they got their names. Sometimes they use a common nickname a gangster-slang version of Sponge Bob but most commonly they are given the derogatory monikers H-Caps, Spitfire or simply Titans. They are often referred to as scrappers, which means, You don't want to mess with these guys.

They are the scourge of street gangs because of the extreme violence that occurs as a result of this gang code. And they are getting dangerously close to taking over.

While these young men and women are still called sponges, I believe this label no longer describes them. At least not completely. As these subgroups of the Crips and Bloods continue to grow and evolve, they have surpassed the violent, physical aspects of this word's usage. They have surpassed the old meaning of the term, sponge. Now, the name sponge has evolved and evolved into a symbol of fear. They are not only violent with words, but the sponge brand has become an ominous mark on an individual's identity. It's a kind of gang sign that can never be changed or washed off. So even if you get out of prison, your mark stays tattooed on your backside as the world continues to reject you.
