They are called Sesile because they are attached to each other. In order obtain food, sponges pass water through their bodies in a process known as filter-feeding. The water is drawn into the sponge through small holes at the base of the sponge’s body. The water is then passed through a series of small pores, each of which is filled with a different type of bacteria.
The bacteria in these pores are able to break down the food that is in the water. This process is called decomposition, and it is the same process that occurs in plants and animals when they decompose.
When a sponge is exposed to water, the bacteria that live in its pores break it down into its constituent parts, such as proteins, carbohydrates, lipids and nucleic acids (the building blocks of DNA and RNA). The proteins and carbohydrates are then broken down further by the enzymes that are present in all living things.
These enzymes are responsible for breaking down fats, sugars, amino acids, vitamins, minerals and other substances into their component parts.

Do sea sponges eat fish?
They’re able to capture and eat a variety of small crustaceans and fish using a system of hooks and gill slits. “It’s a very efficient way of capturing prey, and it’s very easy to use,” .
Do sea sponges make their own food?
Adult sponges stay in the same place. But unlike plants, sponges must take food into their bodies to live. They can not make their own food like plants do. They can be eaten by animals because they are in the same kingdom. In the past, scientists thought that the sponge was a single-celled organism.
However, recent studies have shown that it is actually a multicellular organism, with many different types of cells. These cells are called zooxanthellae, and they are found in a variety of different places in the body, including the mouth, the anus and the gills.
Does sea sponge have life?
Sea sponges are one of the world’s simplest multi-cellular living organisms. Sea sponges are considered animals. They grow, reproduce and survive just as plants do. In fact, they are so simple that they can be used as a model organism for studying the evolution of life on Earth. The sea sponge is a single-celled organism that lives on the ocean floor.
It has no roots, leaves or stems. Instead, it has a tube-like structure called a siphon that allows it to absorb nutrients from the water. The sponge can survive for up to a year without food, and it can grow to be as large as an adult human.
What happens if you touch a sea sponge?
Initially, a stinging sensation is felt. Severe itching may develop as a result of burning, pain, blisters, and joint swelling. In cases with large body exposure to certain sponges, patients may develop a number of symptoms, including a rash on the face, neck, arms, legs, and hands. These symptoms may persist for several days or even weeks.
Do sea sponges have brains?
Sponges are among the most primitive of all animals. They are immobile, and live by filtering detritus from the water. They have no brains or, for that matter, any neurons, organs, or nervous system at all. In fact, the only thing they have in common with other animals is that they live in a watery environment.
The sponge is a member of the phylum Cnidaria;
- A group of animals that includes jellyfish
- Sea anemones
- Many others
These tiny creatures are so small, they can be seen with the naked eye, but they do not have eyes, so they are invisible to the human eye. When they die, their bodies decompose, leaving behind a layer of soft, gelatinous material known as a spongy exoskeleton.
How long do sea sponges live for?
Sponges can live for thousands of years. While not much is known about the lifespan of sponges, some massive species found in shallow waters are estimated to live for more than 2,300 years, according to the National Oceanic and Atmospheric Administration.
Can you keep a sea sponge as a pet?
The chemical balance of the water would have to be exact, the water temp and salt content would have to be within certain levels, and it would have to be maintained that way. Finding the right food at a reasonable rate can be a challenge for sea sponges.
