the sponges most amazing ability
While it is no secret that certain animals can regenerate lost body parts, sponges are undoubtedly the best at it. As sponges can be cut up tiny pieces or even mashed up into a paste and as long as they have two special cells called collencytes (which produce mesohyl the gelatinous matrix in the sponge that forms a sort of psuedotissue) and archeocytes (which produce all the other cells in the sponges body) the sponge will survive and reform into the sponge it once was(although they will look different . As long as a fragment of a sponge has these two cells the animal can survive the most brutal of Injuries and in a few weeks be back to its normal filter feeding self. Making sponges one of the most awesome animals ever!
