    Rhinolophidae or Horseshoe bats emit long and narrowband calls. Fluttering insect prey generates echoes in which amplitude and frequency shifts are present, i.e. glints. These glints are reliable cues about the presence of prey and also encode certain properties of the prey. In this paper, we...

    The article takes a look at two dolphins and one porpoise. The pink river dolphins are found in the Amazon River in South America and use echolocation to communicate and they are an endangered species as their habitat is being destroyed. Bottlenose dolphins live in pods and work as a team to...

    The harbour porpoise is one of the smallest and most widely spread of all toothed whales. They are found abundantly in coastal waters all around the northern hemisphere. They are among the 11 species known to use high frequency sonar of relative narrow bandwidth. Their narrow biosonar beam helps...
