For the study published in the Plos One journal, the researchers held a collection surface over or just above each dolphin’s blowhole as it exhaled in order to collect the samples.
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
Scientists found microplastics in the exhaled breath of 11 dolphins, according to a new study. A wild bottlenose dolphin receives a health assessment in Louisiana's Barataria Bay, in 2018.
