I’m your host, Kate Shaw. This week we have suggestions from Henry and Miranda, so we’re going to learn about some weird but cute frogs! First, Miranda listened to episode 270 about the tapir frog and commented about a little frog native to Puerto Rico that sounds very similar. It’s call the coquí frog and it has an adorable beep! It sounds like this: [frogs beeping] You can definitely hear why the coquí frog is called that. It sounds like it’s saying “coquí.” The coquí is a type of tree frog although most species prefer to live on or near the ground. Instead of webbed toes, their toes have discs that act sort of like suction cups that help them stick to leaves. Different species of coquí frogs are different colors, including brown, green, gray, and yellow. Their tummies are usually white or yellow. Most species are quite small, although a few species grow as big as 3 inches long, or about 8 cm. There are at least 17 species of coquí frog known in Puerto Rico, with more species found in other parts of the Caribbean and in Central and South America. New species are discovered from time to time, including the tiniest species, the Puerto Rican wetland frog. It was only discovered in 2005 and described in 2007. It’s about 15 mm long from nose to butt, or more properly snout to vent, and while males are bright yellow, females are browner. It lays its eggs on the leaves of a plant called the bulltongue arrowhead, and it only lays one to five eggs at a time. Instead of hatching into tadpoles, the eggs hatch into miniature frogs which are ready to hop out and eat lots of ticks, because that’s mainly what this species of coquí eats. And that’s about all we know about this particular species except that it only lives in one small area of Puerto Rico and is critically endangered. Another species of coquí is the golden coquí, which is almost as small as the Puerto Rican wetland frog. It’s yellow or golden in color, or sometimes a more olive green. Instead of laying eggs that hatch into tadpoles that develop into frogs, the golden coquí skips most of these steps and just gives birth to fully developed teeny baby frogs, three to six of them at a time. The golden coquí lives in a small, specific habitat, a moist subtropical forest where bromeliad plants grow. Bromeliads are shrubby plants with succulent-type leaves that retain water. Pineapples are a type of bromeliad, although not the ones the golden coquí lives in. Unfortunately, the golden coquí is also critically endangered and may actually be extinct. No one has seen one since 1981. Most species of coquí lay their eggs on leaves instead of in water. The eggs still need to stay moist, though, so in many species the male will bring water to the eggs. He does this by just dunking himself in water, then returning to the leaf where the eggs are and plunking himself down on the eggs. He will also guard the eggs from potential predators. The eggs of all coquí species hatch into frogs instead of tadpoles. A few species of coquí have been introduced to other parts of the world, either by accident or on purpose, and have become invasive species. This is especially true in Hawaii, where the coquí has become incredibly common and as a result is causing some native frogs to decline in numbers, along with other animals. But in Puerto Rico, where the coquí belongs, people are naturally proud of their loud little frogs. The indigenous people of Puerto Rico,
