What kind of symmetry does the sponge have?
Asymmetry. Only members of the phylum Porifera (sponges) have no body plan symmetry.
Does sponge have bilateral symmetry?
Most animals are bilaterally symmetrical with a line of symmetry dividing their body into left and right sides along with a “head” and “tail” in addition to a top and bottom. Only sponges (phylum Porifera) have asymmetrical body plans.
What is a finger sponge?

What type of symmetry do sponges have quizlet?
Sponges exhibit radial symmetry.
What does the skeleton of a sponge consist of?
Sponge skeletons are made of rod-like silica structures called spicules that are cemented to rocks and to each other with collagen.
Why is a sponge asymmetrical?
Some of them are radially symmetrical, but most are asymmetrical. The shapes of their bodies are adapted for maximal efficiency of water flow through the central cavity, where the water deposits nutrients and then leaves through a hole called the osculum.

What type of skeleton do sponges have?
endoskeleton
In most sponges, an internal gelatinous matrix called mesohyl functions as an endoskeleton, and it is the only skeleton in soft sponges that encrust such hard surfaces as rocks. More commonly, the mesohyl is stiffened by mineral spicules, by spongin fibers, or both.
