Fact Friday
How do you eat when you don’t have appendages? Snakes on land have an expandable jaw that allows them to move their jaws forward in order to eat their prey whole. Eels do not have this capability. Eels, like this spotted moray eel (Gymnothorax moringa), have two sets of jaws to help them feed. The oral jaws capture the prey, while the phalangeal jaws reach towards the oral jaws to pull the prey into its throat.

Sea Turtle
Sea turtles can hold their breath for 4-7 hours while sleeping and resting. How do they do it? Sea turtles are reptiles; like humans, they breathe air. They cannot breathe underwater. When a sea turtle is inactive, its metabolism and heartbeat “slows down,” which decreases the amount of oxygen it uses in its blood. Sea turtles can slow their heartbeat so that it only beats once every nine minutes! For comparison, the human heart beats an average of 80 times in one minute. One breath from the surface can go a long way for these amazing animals.
