Migrating Blue Whales Depend On Memory Than Environmental Hints To Search For Prey


Blue whales attain their gigantic size by depending on their atypical memories to discover established fruitful feeding locations instead answering in real time to emanating prey spots.

Researchers scrutinizing records of both whale migrations and oceanic state in the California Current Ecosystem discovered that blue whales almost flawlessly complement the timings of their migration to the historical median timing of krill production optionally complementing the waves of krill accessibility in any given year.

The discovery propose that blue whales detect preys by depending on memory to get back to secured, exceptional hunting sites that have historically assisted them well but could render it arduous for the whale to acclimatize if new ecosystem alterations emanate due to climate change.

The notion of pursuing the timing of food accessibility along migration path is not uncommon for land animals but it has been arduous to pinpoint in marine beasts as per Briana Abrahms, a research ecologist with the NOAA Southwest Fisheries Science Center.

Abrahms added that it’s known that innumerable genus that migrate on land from caribou in the Arctic to wildebeests in the Serengeti, intensify their existence by painstakingly regulating the tempo and timing of their migrations to search for food as it becomes occasionally available along the way rather than just migrating to get from point A to point B. She further said that blue whales follow the same plan which is augmented by the memory.
