How to identify Pacific white-sided dolphin
You can recognise Pacific white-sided dolphins at first glance by their striking colour contrast: their back and flanks shimmer dark grey, with a broad white stripe on each side running from the eye to the base of the tail. Their belly is clearly set off in white.
At up to 2.5 metres in length and around 180 kilograms in weight, Pacific white-sided dolphins look strong and compact. Their head is short and rounded, the dorsal fin sickle-shaped and conspicuously tall. The white flank stripes clearly set them apart from other dolphins.
