Thanks to a lull in human movement, along with suspended ferry services between Hong Kong and Macau since March, sightings of Hong Kong’s endangered pink dolphins have risen by 30 percent.
The local population of Indo-Pacific humpback dolphins reside in murky waters with little sun, and therefore lack pigmentation. Their bubblegum pink appearance is the result of warm blood pumping through vessels near the surface of the skin.
Scientists estimate that only 2,500 of these rare pink dolphins are left in the wild. But research suggests that the vulnerable marine animals have adapted to the more tranquil environs quicker than expected, and could even be making something of a comeback.
