Stripeless tree frog (hyla meridionalis) - Laryngeal sacs

"So, folks, finally, after long fights for territory, I got hold of a lily pad! After that ...

... I'll take a deep breath and ...

... let my terrific voice ring out to attract a female!":

"Look how the sound waves are to be seen!":

"We are just great guys, aren't we!?":

"My voice is the most voluminous and also the most beautiful one!":

"What a nonsense! Nobody can reach me!":
