Two kayakers were shocked after rowing into a jellyfish bloom off the coast of County Waterford on July 5.<\/p>\n

IRELAND \u2013 Don’t be jealous of two kayakers floating in the Irish Sea<\/a>, who stumbled upon an unforgettable spectacle as a massive jellyfish<\/a> bloom turned the deep blue water into a sea of translucent drifters.<\/p>\n

While filming the jaw-dropping spectacle from a kayak off the coast of Helvick in County Waterford, Ireland<\/a> on July 5, Brendan Cosgrave could only sum it up one way: “That is bananas.”<\/p>\n

The explosion of jellyfish was the result of a massive bloom, and the kayakers happened to be in the right place at the right time\u2014and in the right kind of boat\u2014to witness the natural spectacle up close.<\/p>\n

A jellyfish bloom<\/a> is a natural gathering of thousands of jellyfish in one area, fueled by warm water, abundant fuel to feed on and favorable ocean currents.<\/p>\n

While spectacular to witness, some blooms can include species capable of delivering painful stings to swimmers.<\/p>\n

It’s unclear which species made up the massive bloom, but Lola O’Sullivan, a volunteer with Water Safety Ireland, told RT\u00c9<\/a> that compass, blue and barrel jellyfish are among the species most commonly found in Irish waters this time of year.<\/p>\n

“They’re the whole way over there,” Cosgrave shouted, pointing out just how far the jellyfish bloom stretched across the sea.<\/p>\n","protected":false},"excerpt":{"rendered":"Two kayakers were shocked after rowing into a jellyfish bloom off the coast of County Waterford on July…\n","protected":false},"author":2,"featured_media":545199,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[2386,264,1813,61,60,3738,14733,82,154462,10797,1433,263,168492],"class_list":["post-545198","post","type-post","status-publish","format-standard","has-post-thumbnail","category-wildlife","tag-outdoors","tag-animals","tag-europe","tag-ie","tag-ireland","tag-nature","tag-ocean","tag-science","tag-stay22","tag-summer","tag-viral","tag-wildlife","tag-world-regions"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/545198","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=545198"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/545198\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/545199"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=545198"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=545198"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=545198"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
