Teaching Tuesdays - Fun Facts

Do penguins have teeth? No. Well not normal teeth. Penguins have papillae, structures on the tongue and palate comprised of soft keratin spikes. They curve backwards toward the back of the mouth and work a bit like a fish hook by grabbing onto a slippery fish and moving the fish down the penguin’s throat!
Can you curl your tongue into a tube? Well dolphins can! Along the edges they have tiny frills that connect like a zipper and when curled they form a watertight straw. Baby dolphins insert this tongue straw into the mother’s mammary slit to enable them to nurse while swimming.
Did you know that shark teeth regrow? Sharks lose thousands of teeth over their lifetime, but they can also regenerate their teeth. This happens over a period of months, and the shark is capable of replacing lost teeth as many as 50 times over during the course of their life.
Do dolphins sleep? Yes, but not like we do. While sleeping, a dolphin shuts down only half of its brain, along with the opposite eye. The other half of the brain stays awake at a low level of alertness. This allows the dolphin to control their breathing as they are conscious breathers. Dolphins are often found resting or sleeping in pairs or groups.
Have you ever wondered how a sea star feeds? Well it pushes its stomach out of its body and into its prey. It then secrets enzymes that digest the prey's soft body tissues which can then be absorbed into the sea stars stomach. After devouring the liquified victim., the stomach is then pulled back into the sea stars body. Many sea stars are carnivorous and prey on molluscs including clams, mussels and oysters.
