Acoustic Structure of False Killer Whale (Pseudorca cassidens) Sounds off The Coast of El Salvador
The False Killer Whale (Pseudorca crassidens) is a dolphin found primarily in tropical waters. They are gregarious and have strong social bonds. They are known to form mixed species groups with bottlenose dolphins (Tursiops truncatus) and, in captivity, are known to interbreed and produce viable off...
