Dolphins are getting breathalysed, but not to stop them driving under the influence: a team of researchers has developed a special breathalyser that allows them to check the health of the animals in a non-invasive way.
Because dolphins are “explosive breathers” — exchanging up to 90 percent of their lung capacity in less than a second — collecting just one breath is extremely useful. The device collects and freezes the dolphin’s breath in an insulated tube. These samples can then be used to create profiles based on the different metabolites found therein — compounds that offer clues as to diet, activity levels, environmental exposures and disease rates.
The researchers have already created baseline profiles from healthy dolphins; metabolite profiles that show variance from these profiles indicate that the dolphin’s health is suffering due to disease or other factors.
