Adult sponges are considered animals because they belong to the kingdom Animalia, characterized by multicellularity, heterotrophy (obtaining nutrients by consuming organic matter), and the lack of cell walls. Despite their sessile nature, sponges exhibit essential animal traits, such as specialized cells for feeding and defense, and they respond to environmental stimuli. Their evolutionary lineage shares a common ancestor with other animals, further justifying their classification as animals.
What else can I help you with?
Why are adult sponges said o be sessile animals?
meaning that they live their entire adult life attached to a single spot. Meaning they're attached to some surface.
If adult sponges are permanently attached to solid objects how can they colonize other areas?
The adult sponges can colonize other areas by swimming to them.
Is it true that young sponges move through the water but adult sponges don't?
yes, it is
How do sponges differ from other animals?
Sponges lack a true body cavity.Sponges exhibit radial symmetry.Sponges lack true tissues.Sponges are autotrophs.Sponges have a true coelom.-@leilooni
What animal do not move?
Plenty of animals are sessile, meaning attached to something like a plant. They include sponges, anemones, corals, barnacles, and sea squirts. Their larva larvae do swim around, though corals can reproduce by budding.
Do adult sponges float around form place to place?
No
What kind of symmetry do sponges exhibit?
Sponges are asymmetrical, although a few species have nearly radial symmetry.
Are you a middle adult at ages 51-75?
Yes, though 75 is not consider middle age.
Do adult sponges have body cell walls with many pores?

Does a star fish have a heart?
They do not. Strange as it may seem, many animals don't have heads. Starfish, urchins, coral, sponges, singe celled animals, adult tunicates, jellyfish, and many more, don't have heads.
Does the blastopore becomes the anus of the adult in invertebres sponges protostomes or deuterostomes?
deuterostomes
What are sponge larvae?
Sponge larvae are the early developmental stage of sponges, aquatic animals belonging to the phylum Porifera. These larvae are typically free-swimming and are usually characterized as either parenchymula or amphiblastula, depending on the species. Upon settling, they undergo metamorphosis to develop into adult sponges, which are sessile and filter-feeding organisms. Sponge larvae play a crucial role in the reproduction and dispersal of sponges in aquatic ecosystems.
