Miscellaneous Aquatic Animal Sounds

 

Sometimes I've had the opportunity to record non-fish sounds. A few miscellaneous examples can be found below. For fish sounds see Rountree's Fish Sound Library. Note that a negative audition does not mean the species is not vocal, just that they were silent at the time of auditioning which can happen for many reasons.

Go to the other sound species list.

Pipa pipa 20July2012.jpgSurinam toad, Pipa pipa While in Peru I had a chance to hand audition one Surinam toad on 20 July 2012 at approximately 11 pm. No sounds were detected.

Inia geoffrensisPink river dolphin, Inia geoffrensis While in the Pacaya–Samiria National Reserve in the Peruvian Amazon, I had the opportunity to record pink river dolphin on a number of occassions. Note, that the Tucuxi river dolphin (Sotalia fluviatis) were sometimes present. Usually a single pair or small pod. For more information go to the Amazon project page

Here is a short video clip of Pink River dolphin recorded about 3 pm on 21 July 2012. The audio includes aerial sounds and underwater sound played over a loudspeaker. Towards the end of the video you can hear and see bubbles that the dolphin blew under our drifting boat.

Listen to the underwater sounds recorded during the video (not synced exactly to the video).
