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.

Coral Nursery
Scientists are trying to mitigate the decline of corals. One way to do this is to grow and “plant” them. Coral ecologists grow corals in nurseries created either on land or in the ocean. As with most plants, you can break a leaf off and grow it into a whole new plant. The same process can be used to grow coral. When a piece of a coral is broken off, it can be regrown into another coral, and when they are large enough, they are transplanted from the nursery to the coral reef.
