Sponges represent one of the earliest forms of multicellular life, showcasing a significant evolutionary innovation in their ability to filter feed through a porous body structure. This simplicity allows them to efficiently extract nutrients from water, establishing a fundamental ecological role in aquatic ecosystems. Their cellular organization, which includes specialized cells for different functions, marks a critical step in the evolution of more complex organisms, laying the groundwork for further developments in multicellularity and tissue specialization.
What else can I help you with?
Which phylum contains the simplest animals?
The phylum Porifera contains the simplest animals, known as sponges. Sponges lack tissues and organs, and their body structure is very basic compared to other animal phyla.
What evolutionary innovation is associated with the simplest animals the sponges?
multicellularity ------------------------------------------------ Sponges are simple aggregations of single cells which come together for mutual benefit. If you liquidise a sponge, the cells it is made form will come together again to reform the sponge. Thus sponges (or something like them) were probably the first step in the evolution of multi-cellular organisms.

Do sea sponges have back bones?
No. Vertebrates are animals with backbones. Sponges are about the simplest multicelluar organisms around.
Why do biologists classify sponges as animals?
Sponges belong to a group of animals that scientists classify as Po-lifer and are among the simplest of animals, lacking tissue and organs. They filter water through the various chambers within it, absorbing nutrients
What is sponges plants or animals?
Sponges are animals of the phylum Porifera
What are the Simplest group of invertebrate called?
Sponges (Porifera)Sponges are aquatic animals that make up the phylum Porifera (pohr-IF-uhr-uh). These simple organisms clearly represent the transition from unicellular to multicellular life.
Are sponges autotrophs?
No. Sponges are animals, which are heterotrophic.
Is a slug a sponge?
No. Sponges are the simplest animals and they are aquatic and sessile (attached to a substrate). A slug is in the Phylum Mollusca in the Class Gastropoda.
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.
What species are sponges?
Sponges are animals of the phylum Porifera.
What group are sponges divided into?
Sponges are animals of the phylum Porifera
