(Smithsonian Tropical Research Institute) Glassfrogs may be somewhat see-through, but they have still managed to a hide an important secret--they are dedicated mothers and fathers that invest time in brooding their eggs. Smithsonian scientists documented previously unknown parental-care behavior using detailed observations of 40 species of glassfrogs in Central and South America. Their discovery rewrites assumptions about how caregiving evolved in this family of translucent, tree-dwelling frogs.
