Their thick no-neck physiques and loosely interlocked vertebrae make them strong and flexible enough to surf the waves and navigate ice and rocky shores. Seals have developed special features to keep them from getting the bends.Most mammals have 13 pairs of ribs, but seals have two extra pairs so there is more room for their slightly larger lungs.
