Porifera cake? (6)
I believe the answer is:
sponge
This clue might be a double definition.
'porifera' is the first definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe there's a link between them I don't understand?
'cake?' is the second definition.
(sponge cake is a kind of cake)
Can you help me to learn more?
(Other definitions for sponge that I've seen before include "Bathroom scrubber" , "Aquatic creature; cake" , "Porous mass of fibres found in the ocean" , "Light cake; aquatic invertebrate" , "Sea animal found in bathroom as washing aid" .)
