I want to know the answer to the following question:
What type of symbiosis seen between bryozoans and hermit crabs?
All the background I'm provided with is that "The bryozoan colony (Acanthodesia commensale) develops a cirumrotatory growth and offers the crab (Pseudopagurus granulimanus) a helicospiral-tubular extension of its living chamber that initially was situated within a gastropod shell.". Is that enough to answer the question?
Answer: no
