Can there possibly be anything more 'cruel' than this in wildlife?

Watching a documentary on the Great Barrier Reef, I saw the difficult path that sea turtle hatchlings have to go before they reach the (relative) safety of the ocean.
From the moment they come out of their protective eggs and head for the coastline they are attacked, first by birds that are awaiting them who’ll feed their youngsters with them, and then by rock crabs.
This appears to be so cruel; you are just minutes alive and then your life can be cut short immediately.
Is there anything similar or more ‘cruel’ in nature, that you know of?
