Purple Tube Sponge
The name ''Porifera'' means pore-bearing, as Porifera consist many tubes of various sizes through which the water flows.
Porifera are the most basic known form of multi-cellular animals and do not show segmentation.
Flagellum are used to guide the water and bacteria or algae through the asymmetrical body.
Porifera do not have tissue, organs, or a nervous system but rather cells which only perform their duty.
Can produce both sexually and asexually
Each Purple Tube Sponge is Hermaphroditic, able to act either male or female, although they only act as one at a time. Fertilized eggs are larvae that float freely until they attach to a coral wall and become a small sponge.
Can grow to 5 feet long
Habitat and Niche
All Porifera live underwater, and the Purple Tube Sponge lives in tropical water, in water shallower than 100 feet. Sponges attach to solid rock underwater and grow outwards. Sponges help the ecosystem by turning nitrogen into a gas, then letting it exit. This keeps nitrogen levels low and the environment sustainable. They eat bacteria and algae, helping to keep algal levels from exploding.
