Seal Skeletons Diagram

Take a look at these two skeletal diagrams that beautifully illustrate the evolutionary journey of seals. The top one represents an ancient, more terrestrial ancestor, showing a skeleton built for movement on land with distinct legs. Below it, you'll see the skeleton of a modern, aquatic seal, clearly adapted for life in water with its streamlined form and modified flipper-like limbs. It's a fascinating side-by-side comparison that highlights how species adapt to their environments over time.
