An underwater videographer has shared enchanting footage of a lion\u2019s mane jellyfish during a night dive in the Salish Sea \u2013 a marginal sea of the Pacific Ocean. The creature was so gigantic that it took him over a minute to find it after first spotting its trailing tentacles.\u00a0<\/strong><\/p>\n

\u201cSeveral minutes into the dive, I noticed a long, thin tentacle trailing overhead, stretching far beyond my vision,\u201d says underwater videographer\u00a0John Roney<\/a>\u00a0on\u00a0Instagram<\/a>. \u201cI followed it through the darkness for over a minute before coming upon a giant lion\u2019s mane jellyfish<\/a>.\u201d<\/p>\n

His footage shows the enormous jellyfish pulsing through the dark water as marine snow drifts gently downwards behind it. The artful footage lingers on the animal\u2019s brightly coloured tentacles, which “have these deep, vibrant orange, purple and crimson colours that I love to film,\u201d he says.<\/p>\n

Lion\u2019s mane jellies are one of the world\u2019s largest species of\u00a0jellyfish<\/a>\u00a0and they have a nasty\u00a0sting<\/a>. \u201cFair warning,\u201d says Roney. \u201cThis is a jellyfish you definitely don\u2019t want to touch.\u201d<\/p>\n
