Polyfera (sponge) is one of the well-known groups of invertebrates. One of the more amazing things about sponges is their ability to be damaged. Because the cells are not connected within the tissue, they may separate and then reassemble.
Can the sponge regenerate damaged parts?
The extraordinary ability of the sponge to regenerate is manifested not only by the recovery of damaged or lost parts, but also by the complete regeneration of adults from fragments or single cells. When returned to good condition, these fragments form a complete sponge. ..
What happens if I tear the sponge?
Sponges are the only animals that can reconstruct themselves when broken down to the cellular level. A sponge is passed through a sieve to break down the cells. The cells recognize each other and reshape into small new sponges.
Is the sponge fragile?
The siliceous skeleton of the sponge is fragile, and these organisms are easily destroyed by physical impact. The sponge near the trawl net is shattered or completely removed. Although less harmful, hook-and-line fishing and crustacean capture can also damage the sponge.
What if the sponge dies?
Because it is sealed with a sufficient amount of food, the cells survive even if the remaining sponge dies. When the condition improves, the cells grow into new sponges. Sexual reproduction is also common among sponges. Most sponges are hermaphroditic, meaning they produce both eggs and sperm.
