Some cetaceans however, such as the dolphins have only simple peg like teeth. This new article describes how the development of these teeth took place after land mammals moved back to the oceans to develop into the cetacean family. Full details of the article here.

14th February 2013 – The Wildlife Conservation Society have been involved in publishing a paper on genetic investigation into the population size of Humpback Whales. During the 1950’s numbers in the North Atlantic reduced to several hundred. The population is now estimated to be around 17,000 far short of the estimated quarter of a million calculated to have existed pre-whaling. Full details can be found at http://www.wcs.org/wcs-org/press/press-releases/humpbacks-pre-whaling.aspx

26th October 2012 – There is quite rightly some concern over noise levels we cause in the oceans. However, some recent research has calculated that pre 19th century populations of whales made an equally loud din! Read all about it here.

20th October 2012 – Bowhead Whales are on my bucket list. Ever since I read about the Harpoon that was dated 1890 being removed from a Bowhead recently caught in the Arctic I’ve been hooked on them.  They are thought to live for up to 200 years. There has recently been some research done on the DNA of live Bowhead whales and of ancient artefacts (carvings, ancient baleen and even toys made from whale bone among other items). The conclusions are unsurprisingly that the population dipped probably due to whaling although surprisingly it seems the various populations are very interchangeable and individuals have no difficulty in navigating pack ice to chance populations. Read all about it here. Fascinating bit of research.

18th October 2012 – Apparently given Dolphins can rest half their brains at any one time. It has been discovered that dolphins can maintain concentration for aperiod of at least 15 days. Read the full research here.

18th September 2012 – A research document done in part by St Andrews University in Scotland has determined that in the last 30 years or so only 25% of the world’s oceans have been surveyed for cetaceans. Only 6% of them have been surveyed frequently enough to determine trends in population levels. You can read the full paper here.
