It's our final swim history episode of 2025! Featuring special guest, ultramarathon swimmer John Hancock who is back for his third episode to celebrate the 150th anniversary of Captain Matthew Webb's English Channel crossing. We talk about:

• Captain Webb's astonishing Channel swim in 1875, a feat that hadn't been achieved before and was not repeated by anyone else for more than 30 years.
• The life story of the Captain – his heroism, his daring escapades, and his tragic final swim.
• The English Channel's swimming legacy, with facts and figures (mostly cobbled together from Wikipedia and the LongSwims database) and high achievers – including Gertrude Ederle, the first woman to swim the Channel in 1926, and Sarah Thomas, who achieved a quadruple crossing in 2019.
• How the English Channel compares with the Cook Strait (John has swum the Strait and was on the support boat for Wellington swimmer Rebecca Hollingsworth when she swam the Channel in 2024).
• Wellington coach Phil Rush's unbeaten records for his double and triple crossings of the Channel in 1987 (Phil also has his own Swim Chats episode).
• Captain Paul Boyton, who in 1875 achieved the first 'assisted' crossing of the Channel wearing an inflatable rubber suit of his own design, just a few months before Captain Webb's 'unassisted' swim.

If you're an ocean swimmer, you've probably encountered jellyfish at some stage. Depending on the species these watery, tentacled, heartless/ brainless/spineless (literally) invertebrates can dish out a painful sting!

Earth Sciences NZ (formerly NIWA) marine scientist Dennis Gordon came on the podcast to answer my questions. In this episode, we talk about:

• What is the definition of a jellyfish?
• What are their life stages?
• How do they move around?
• How do they still sting people even after they've washed up on the beach?
• Common species such as moon jellyfish and lion's manes, bluebottles / Portuguese Man O'Wars and box jellyfish – how dangerous are they?
• What's the best way to treat a painful sting?
• What are salps and sea lice?

Here's a link to the 'Jiggling Jellyfish' PDF Dennis mentions, with lots of colour photos to learn more and identify the jellyfish we might see in NZ waters.

Have a look at some of Ernst Haeckel's beautiful illustrations from his Art Forms in Nature book (Kunstformen der Natur, 1904).

If you spot anything you can't identify on the beach, in rock pools or in the water, you can send a photo to Earth Sciences NZ and an expert can help to solve the mystery (this is a free service and they welcome new photos).
