Bioacoustics studies help scientists discover things never before known about all kinds of animals, but especially marine life -- on this episode of the Mongabay Newscast we go under the waves to share new recordings of cetaceans (whales and dolphins) from southern Africa and hear from researchers what they think the sounds & songs may mean.

Dr. Tess Gridley's team recently discovered that humpback whales sing in South Africa's False Bay, and she plays some brand new recordings they just captured.

Sasha Dines also joins the show to share her PhD studies of Indian Ocean humpback dolphins, which focuses on these animals' signature whistle calls.

*Turn up the volume to fully appreciate these songs, roars, growls and whistles!

Host Mike G. also discusses the upcoming African Bioacoustics Community conference with his guests, this is a virtual event aimed at bringing more researchers into the acoustic sphere to better understand the continent's incredible natural heritage.
