In recent years, very small, but with increasing rates, fin whales and humpback whales migrate into Baltic sea including mother and calf pair. Now extinct Atlantic grey whales (remains found from Gräsö along Bothnian Sea/southern Bothnian Gulf and Ystad) and eastern population of North Atlantic right whales that is facing functional extinction once migrated into Baltic Sea. Other notable megafauna include the basking sharks. Satellite images taken in July 2010 revealed a massive algal bloom covering in the Baltic Sea. The area of the bloom
