Fact Friday
The tongue-eating louse lives up to its name, or at least the females do. She enters a fish’s body through the gills and cuts off the circulation to the fish’s tongue. When the tongue falls off, she becomes the fish’s new tongue, feeding on the fish’s blood and/or mucus.

Leopard Sea Cucumber
Sea cucumbers are often referred to as “earthworms of the sea.” These strange-looking creatures are extremely beneficial to coral reefs. They use their tentacles to shovel sand, tiny organisms, and detritus into their mouths. Similar to earthworms, they provide “fertilizer” or food for other animals. They do so by excreting waste products such as calcium carbonate and ammonia, which provides nutrients for other animals like corals.
