After watching SpongeBob SquarePants, the average person intuitively thinks of the kind of square cleaning utensils commonly used in the kitchen or bathroom for brushing and cleaning, in fact, it is not surprising that there is such an association; because the ancient Greek residents living on the Mediterranean coast have long known how to use the strong regenerative ability of sponges, cut the sponge into small pieces, throw it back into the sea to let it grow, and then dry it, use it for washing and cleaning, the function is similar to today's vegetable melon cloth, and later because of the prevalence of plastic, "living sponge" was gradually "killed" Plastic sponge" replaced to this day.
The cartoon character SpongeBob square is square, which also causes the public to have the most intuitive impression and association of sponges, in fact, the real living sponge looks strange and colorful, and has a different appearance.
The real sponge is actually a moving aquatic animal in the sea, and scientists estimate that there are about 10,000 species worldwide, but there may be many more species that have yet to be discovered. Sponge is a fairly ancient organism, about half a billion years ago in the Cambrian explosion of life in the ancient geological age, has appeared in the ocean, is a single-celled organism (such as bacteria) and tissue-type organisms (such as jellyfish) between the multicellular organism, its body has many water holes, the use of water flow in and out of the body inside and outside the feeding, breathing, excretion and reproduction and other functions, simply put, is a complex water pipe system. This unique morphological and physiological function, distinct from that of other organisms, has allowed taxonomists to classify them separately under the porous Phylloscopus Porifera.
Sponges vary in body shape, and even the same species will change depending on the habitat, including shape and color, which may be the inspiration for SpongeBob SquarePants' nonsensical personality! The water pipes formed in the sponge body are often also the habitat of many marine organisms, of which a couple of shrimp couples who have lived for life are the most famous, and the Japanese call it "Kai Lao Tong Cave", which is often used as a blessing gift for newlyweds.
