D Question 19 5 pts Paragraph Baleen whales don't have teeth; instead, they have hundreds of tightly packed, springy baleen plates that grow down from the upper gums. These plates are made of keratin, the same substance as human fingernails. Baleen whales also have paired blowholes -- nostrils, in fact, which are on the top of the head. Some baleen species graze peacefully as they move through the water, rolling slowly through the surface with their mouths yawning wide open. Because the baleen plates have a smooth outside edge and a bristly inside edge, water can flow freely through the whale's mouth, but shrimp-like krill plankton, and small fish get caged inside. Find another pattern and show the details.
