Research is being carried out into a species of clam found in Isle of Man waters which is thought to live for up to 500 years, making it one of the oldest creatures on Earth.
And there's a chance to learn more about the Ocean Quahog this weekend, when Dr Paul Butler, a scientist from Bangor University, gives a talk on the ancient shellfish.
Just under 500 years ago, when clams now living in Manx waters could have been alive, Henry VIII became King of England, and a little over 400 years ago a Shakespeare play was performed in public for the first time.
Fiona Gell from the Isle of Man Natural History and Antiquarian Society, which has organised the lecture, says, from a conservation point of view, it's important to find out more about the extraordinary creatures (listen to audio file below):
The lecture is at the Manx Museum in Douglas, at 2.30pm on Saturday.
Researching your Manx family history can be a very interesting and rewarding hobby. Trace your roots in the Isle of Man with our helpful of guide.
