New research has discovered a third species of toothed whale in which the female members appear to go through a similar condition to the menopause in women, and then survive for many years long after they are no longer able to reproduce.
A species of whale that was only identified for the first time in 2003, has now been discovered living in the waters around Sri Lanka.
A rare white Risso's dolphin has been sighted in Monterey Bay in California, nearly two years after the dolphin was first seen as a calf.
It is unclear whether the dolphin is a true albino or leucistic, a condition in which there is only partial loss of pigmentation. However, one photo taken of the dolphin suggests it may have pink eyes, which would indicate a true albino.
Researchers from the University of Western Australia seem to have uncovered the reason behind unusual behaviour by male humpback dolphins – flirting!
Whales and dolphins are renowned for their sensitive hearing but new research published in Current Biology suggests this was not always the case.
Recently, Norway announced that the entrance to the Global Seed Vault in the Arctic was flooded after very high temperatures caused the permafrost to melt.
A study by the International Fund for Animal Welfare had produced a new estimate for the number of sperm whales living in the Mediterranean Sea.
Published by the International Whaling Commission, the research produced a figure of 1678 whales in the western part of the sea and 164 in the eastern region, giving a total of 1842 sperm whales.
A new report published by The Royal Society looks at the reasons behind how modern day whales evolved to be so much bigger than their ancestors.
