Dolphin poo plays 'significant role’ in helping coral reefs survive, says new study.

Dolphin poo plays 'significant role’ in helping coral reefs survive, says new study. Spinner dolphins, famous for their acrobatic marina displays, have some very special excrement. Their poo has “reef-enhancing nutrients” which are not to be underestimated, a report by Zoological Society London (ZSL) finds. The dolphins are giving threatened coral reefs in the Maldives and Chagos Archipelago a helping hand by pooing in the shallow lagoons. Published this week, the study shows that the amount of nitrogen absorbed by spinner dolphins during their daily commute can improve coral reef productivity and resilience. The species plays a “significant role” in supporting the vulnerable ecosystems in this region and scientists are calling for their protection.
