Reproduction • Sponges can reproduce by mating and asexually • The asexual way is called budding • It grows buds that detach from the body and forms another sponge • They can also reproduce by mating • Most sponges are Hermaphrodites
Reproduction • They release reproductive cells that looks like smoke that goes to another sponge • The reproductive cells fertilizes the egg • When the egg is hatched, the larva swims around • Later, it settles on a rock and grows into an adult
