The sea-nettle is the marine creature today called the “jellyfish”, with a round body and dangling, frond-like tentacles. The creature was known in period – the illustration is taken from Gulielmi Rondeletii’s Libri de piscibus marinis: in quibus verae piscium, published in 1554 – but no examples of the sea-nettle’s use in period armory have been found. The sea-nettle has its tentacles to base by Society default.
