I want to know the answer to the following question:
Some seabird species only come ashore for what purpose?
All the background I'm provided with is that "Several families of birds have adapted to life both on the world's oceans and in them, with some seabird species coming ashore only to breed and some penguins have been recorded diving up to 300 metres (980 ft).". Is that enough to answer the question?
Answer: yes
