Strangely a sponge is classified as an animal, even though it has no eyes, ears, mouth, heart, stomach or even a basic nervous system.
The main reason for this classification is due to the way that they feed. Sponges do not make or produce their own food in the way that plants do, they actually capture their food.
The entire surface of a sponge is covered in tiny pores. The smallest of marine life and plants flow into the pores and then enter a system of water canals throughout the main body of the sponge. Once they have been captured in this way, the food is digested and the canal system washes away the waste. Since sponges do not actively capture their prey, they are in effect acting like a filter or sieve.
Most of the sponges which are sold as such are simply synthetic materials which have been made to resemble natural sponges, which given that they eat and produce body waste, may be a good thing !
Sponges are considered to be the simpliest animals in the animal kingdom. They are also called porifera, meaning pore-bearer. Sponges live in fresh and salt water, oceans, and warm, shallow water. They vary in color ( pink, scarlet, white, brown, red, orange, or green ), sizes and shapes. The most common is green. Sponges are animals that do not have arms, heads, and internal organs. They are attached to rocks and plants under the water so they are called sessile animals. Shapes of sponges may be round; some are shape like vases while others have the shape of objects to which they are attached. Sponges are radially symmetrical, meaning there bodies can be divided into two equal parts by cutting through the center in any direction. The body of a sponge has many pores where water enters. Tiny plants and animals in the water are the foods of sponges. The waste product of sponges also come out from these pores. Some sponges have tiny, hard skeletons called spicules. Others have flexible skeletons called spongin which contains protien. Sponges reproduce asexually. Buds grow on the present sponge in asexual reproduction. Most sponges undergo the process of regeneration, meaning they have the ability to replace lost body parts or to repair damaged body parts. Sponges are aquatic invertebrates with bodies full of pores. Sponges have osculum, which means they are the large pores that pushes the water out, absorb oxygen and food. ...that is all
Yes the sponge is an animal
Hi I'm a science teacher, and yes a sponge is a ANIMAL.
Scientists disagree upon this topic. Many scientists believe that it is an animal because it is a heterotroph, not an autotroph. (Heterotrophs do not produce their own food, wheras Autotrophs do). Still other scientists believe that it is a plant.
IF THIS IS A QUESTION FOR ANY TYPE OF SCHOOL WORK, TRY TO WORK IN THAT SCIENTISTS DISAGREE. IF YOU CANNOT, JUST CLASSIFY IT AS AN ANIMAL, BECAUSE THAT IS PROBABLY A SAFER BET.
Its a fish... Have you ever seen spongebob squarepants well hes a sea sponge so its a sea sponge your on about its kinda eeerrrm.... To be honest thats a really good question you just asked because its a fish but I'm not sure if its a plant hehehe
I believe it would be an animal and here's why: Wikipedia
It is a sponge, a sponge is a sponge.... Cause there is a sea sponge, a bath sponge and a mr. Clean magic eraser sponge. So it depends on which one you are talking about! SO I JUST HAD THE RIGHT ANSWER! BURN TO ALL THE OTHER PEEPS WHO PUT ANIMAL OR SPONGE!
A sponge is a plant and the scientists think that the first life on earth is in the shape of a sponge about 4 billions years ago.
