Cnidaria are diploblastic animals, in other words they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick.

Coral is nor arthropod , sponge or echinoderm , A coral is a cnidarian also called a coelenterate because it possess cnidocytes , stinging cells , gastrovascular cavity ,tentacles which are cnidarian charters .
a jellyfish is a cnidarian and closer related to coral and sea anemones however they are similar. A sponge lacks a nervous system, Cells in each layer are not bound together, has many cells in the middle "jelly" layer, and -likely their most distinguishing feature- the Cells in a sponge's outer layers can move inwards and change functions.
They are similar because both cnidarian and a sponge is that they both live in water.
Lemon pudding and pie filling. The kind you cook.

A sponge cake can be baked in layers without a tube pan.
Sponges have two germ layers therefore they are diploblastic.
A porifera is a phylum (or group) of animals, mainly occupied by the sponge. They consist of jelly like mesohyl in a layer in between two other layers, made up of cells.
Sponge and cotton are absorbent.
When slicing the sponge layers in the layer cake, they must be sliced evenly. They must also be perfectly level, which means cutting off any parts where the cake has risen more than the other parts (such as the top centre of the sponge) in order to acheve a flat surface. Thin layers of sponge are generally more appealing than thick layers. Also, a layer cake is typically around half sponge, half filling/frosting. This means that creating the filling and frosting should be given equal (if not more) attention than creating the sponge layers. Try to use good quality products for the filling/frosting, because they will be quite noticable.
