Life beside the Kuroshio
Not everyone wants to live beside a busy road. But when that road is a powerful ocean current—a highway at sea that is part of the natural environment—the benefits are immense.
The warm Kuroshio Current, which originates in the Philippines, flows northward along Taiwan’s east coast and continues toward Japan. Warmer than surrounding waters, clear, and deep blue, this “highway” moves swiftly through the Pacific at a speed of between 100 and 200 centimeters per second. Where the seabed drops steeply, the current surges upward, bringing nutrients to the surface and drawing migratory sea dwellers such as mahi-mahi (dolphinfish), billfish, and tuna.
Whales and dolphins are also among those drawn here. According to Turumoan, its whale-watching boats encounter cetaceans on more than nine out of ten trips.
Ray Chin, Taiwan’s first professional photographer specializing in underwater cetaceans and a Kuroshio volunteer, says Taiwan’s greatest advantage as a whale-watching destination is its biodiversity: Of roughly 90 cetacean species worldwide, about 30 have been recorded in waters around Taiwan.

Species often seen from whale-watching boats include Fraser’s dolphins (left, photo by Lan Chen-feng); spinner dolphins (center); and the rarely sighted sperm whale (right).
