Oh, dude, let me break it down for you. So, gemmules are like these little sponge babies that can survive tough conditions, but larvae are like the cool kids who can swim around and find new homes. So, if you want your sponge population to spread far and wide, larvae are the way to go. Gemmules are more like the backup plan for when things get rough.
Sponges can reproduce sexually or asexually. They can reproduce through producing eggs and sperm that are released into the water where they can combine to form larvae. Asexual reproduction can occur through budding, fragmentation, or producing gemmules.
yes, it is
Sponges do not give birth. The only animals who give birth to live young are mammals. Sponges reproduce by releasing sperm or eggs into the sea. The sperm and eggs just mix up in the water and form tiny sponges. The "babies" float around until they land, where they grow into new sponges. Some sponges can also form a "bud" that grows into a new sponge without any sex involved.
sponges let the water enter through the canal and circulates all over the body.
It's commonly believed that sponges are a group of animals that don't go through the gastrula stage. However, some scientists disagree and believe that sponges do go through gastrulation.
osculum - a large opening in a sponge through which water flows out of the sponge. Sponges may have more than one oscula.
In water through canal system .
Sponges are invertebrates, meaning they do not have a spine. Sponges are soft fleshy animals that maintain their structure through the fibers in their body and water pressure.
Sponges eliminate carbon dioxide and cellular wastes through diffusion. As water flows through their pores, oxygen and nutrients are absorbed, while waste products are released into the surrounding water. Sponges do not have specialized organs for excretion, relying instead on passive diffusion.
1.most sponges are hermaphroditic, having the ability to act as both males and females. when acting like a male, the sponge releases a substance called sperm n the water. when a sponge of the same species catches a the sperm, it will form the larvae witch will develop in the sponge after a while. when the larvae are ready, the sponge will release them into the water. that's one of the ways! love, science lover!

Some animals that eat sponges include sea slugs, sea stars, certain species of fish, and turtles. These organisms feed on sponges by either picking at them or by sucking them in through their mouth openings.
