The small molluscs, which can be found in coastal areas all around the world, were studied for a paper in the Journal of the Royal Society Interface.
Trinity scientists found that the limpets they studied were able to sense minor damage to their shells from weathering or predator attacks, and repair them much in the way mammals heal broken bones.
Meanwhile, sea sponges recently discovered in Ireland’s deep ocean territory could hold special medicinal properties, according to The Irish Times.
Samples taken during the recent Marine Institute expedition are being tested for their effectiveness in treating cancer, Parkinson’s disease, Huntington’s disease, epilepsy and other conditions.
The relevant chemicals are produced by the sponges as part of their defences against competing marine organisms, and NUI Galway’s Dr Louise Alcock hopes to see positive results within the next year.
