On the afternoon of March 16, 2024, during the routine annual follow-up investigation of the spotted seal, 4~6 EAFPs were found in the waters (37 59 '03 ''N, 120 39' 48'' E) at the south side of Danglang Island (also known as Dabian Island). We found that there was an individual with solid white color, which was often accompanied by a black one. The porpoise roughly the same size as the accompanying individual, was slightly thin, but its body color was completely white, and no significant black deposition was seen
