Australian researchers were performing a genetic survey of Poseidon’s ribbon weed (Posidonia australis), a species of seagrass growing widely in Shark Bay, off the westernmost tip of Australia. Researchers collected shoots from across the bay and examined 18,000 genetic markers to create a “fingerprint” from each sample. They had aimed to discover how many plants made up the meadow. When the DNA results came in, they made a remarkable discovery.
The seagrass, covering over 180km, an area three times the size of Manhattan, is, in fact, a single plant, having grown from a single seed over at least 4,500 years. The self-cloning plant is also the largest single plant in the world.

Andrew Bedwell hopes to set a new world record for sailing the smallest boat to cross the Atlantic. His vessel, Big C is just over 1m/3.2ft long. If all goes according to plan he will set off in May 2023 from St Johns, Newfoundland, and finish off Lizard Point in Cornwall.
