How many spines does a penguin have?

All penguins have a spinal column that their skeletal frame is built around, but the answer is penguins have hundreds of flexible spines in addition to their spinal column.

The hundreds of spines line the roof of their mouth and tongue. Angled backward, these barbs keep fish and other prey from escaping after they have grabbed a meal with their beak.

Penguins do not have teeth so the spines in their mouth force the food down their throat. Since they do not have teeth, penguins eat their food whole.
