What sound does a Bullfrog make?
Answers
The Bullfrog sound like "Riv-Riev-Riv-Rieeev"or like "Rehm-Rehm-Reiiim", that is according to my observance of bullfrogs. They make spontaneous short produced sounds called as "calls" either to attract the opposite genders of same species in a really harsh pitch changing or increasing with time.
It's directly released from the throat of the Bullfrog by producing a "vibration" just like we do to produce sounds for communication to other humans, for different purposes. To produce those calls via croaking the harmony of their throat which constitutes the pair of vocal cords, tracheal cartilage, etc. the pair of lungs (which store the air, for circulation, usually for continuous or rapid croaks) and the mouth (constituting the nostrils for extraction of air to continue the cycle of "croaking").
In all, the Male Bullfrog (alike the female ones; quieter and more smoother croaks) are releasing continuous or a unpremeditated croaking with a range of harmonical deviating characteristics for a "Behavioral Acoustic Alternation" or "Advertisement Calls", which are primarily made for bolstering male attraction over female, for mating induced populations, recognition and identification of "louder calls" to make one species aware for any invading, annexing, confictual attacks, etc. with a bout of shortly produced wavelengths and lower frequency ranges, increasing over time by variable changes in air sac induction (storage of air, over a period of given time).
