Description
English: A male of the Fire-bellied Toad (Bombina bombina) calling on a pond surface. Above the "normally" looking animal, in the middle is the phase prior to the formation of sounds: the body is distended like a balloon, in addition, the throat bubbles are inflated with air. Below is the moment of phonation: The inhaled air is compressed by muscle contraction from the throat bubbles above the glottis of the larynx to the lungs. Here, the toad's body serving as a resonance amplifier makes vibrations which are displayed on the water.
Deutsch: Ein Männchen der Rotbauchunke (Bombina bombina) rufend auf einer Teichoberfläche. Oben sieht man das noch nicht mit Luft aufgepumpte Tier, in der Mitte die Phase vor der Lautbildung: Der Körper ist ballonartig aufgetrieben, zusätzlich werden die Kehlblasen mit Luft aufgepumpt. Unten der Moment der Lautbildung ("Unkenruf"): Die eingeatmete Luft wird durch Muskelkontraktion aus den Kehlblasen über die Stimmritze des Kehlkopfes in die Lungen gepresst. Dabei macht der als Resonanzverstärker dienende Körper Vibrationen, die auf dem Wasser sichtbar werden.
