Someone should let Kermit know he has a new relative.

A new species of frog called the Hyalinobatrachium dianae has been found in Costa Rica. Similar to the glass frog, the lime-colored amphibian has translucent skin on its underside and has eyes that make it look like the famous Muppet, Kermit.

The frog's translucent belly makes its internal organs easy to see, but its those big, white eyes with perfect black centers that give a distinctive, Muppet-like look.

The frog was photographed by Dr. Brian Kubicki, who detailed the new species in a study with zoologist Stanley Salazar and Robert Puschendorf. Dr. Kubicki named the creature after his mother, Janet Diana Kubicki, according to the Costa Rican Amphibian Research Center.

The frog was previously missed by scientists who were studying the area, but the authors attribute this to the frog's particular call. Dr.Kubicki says it sounds more like an insect than a frog, according to The Tico Times, a Costa Rican news site.

The study describes the frog’s "advertisement call" as "a single tonal long metallic whistle-like note." No word yet on whether the new species enjoys playing the ukulele or has an affinity for fashionable pigs. Further study will be needed.
