A massive\u00a0ocean sunfish<\/a>, estimated to weigh more than 900 pounds, was found stranded on a Cape Cod\u00a0beach\u00a0earlier this week, a tragic sight that\u2019s unfortunately all too familiar this time of year as the vulnerable species migrates toward warmer southern waters.<\/p>\n

The adult female\u00a0ocean\u00a0sunfish washed ashore at the mouth of the Herring River in Wellfleet,\u00a0Massachusetts, on Cape Cod\u2019s inner shore along Cape Cod Bay.<\/p>\n

The massive sunfish, one of the\u00a0ocean\u2019s gentle giants, known to bask at the surface and dive into deep waters, was found dead on the beach by someone walking along the shoreline.<\/p>\n

The species ranges across tropical and temperate oceans\u00a0worldwide, from Iceland to Chile, and annually migrates to warmer\u00a0wintering\u00a0waters.<\/p>\n

Ocean sunfish can weigh more than 2,000 kilograms, or about 4,400 pounds. <\/p>\n

At roughly 900 pounds, the\u00a0fish\u00a0captured in tragic images was still an impressive giant.<\/p>\n

The fish\u2019s ovary alone weighed 13.2 pounds, researchers said.<\/p>\n

Volunteers with the\u00a0New England\u00a0Coastal Wildlife Alliance (NECWA), a\u00a0grassroots wildlife nonprofit<\/a>, responded to the stranding \u2014 an unfortunately familiar sight this time of year.<\/p>\n

Each year, healthy ocean sunfish meet the same unfortunate fate on their\u00a0migration\u00a0journey south to warmer\u00a0wintering\u00a0areas during the\u00a0fall.<\/p>\n

While following the Atlantic coast on their seasonal migration, ocean sunfish can become trapped in Cape Cod Bay, where the peninsula\u2019s hook-shaped coastline and dramatic tides funnel them into the shallow, narrowing waters of Wellfleet Harbor.<\/p>\n

For these open-ocean fish, the harbor can become a deadly trap.<\/p>\n

Ocean sunfish accustomed to deeper waters can be caught by shallow waters and retreating tides, where they can strand and die, like what happened to the massive adult female sunfish recovered earlier this week.<\/p>\n

The gentle giants that inhabit tropical and temperate waters worldwide are classified as \u201cVulnerable\u201d on the\u00a0IUCN Red List<\/a>, the world\u2019s most comprehensive inventory of species\u2019 extinction risks and conservation statuses.<\/p>\n

Despite their vulnerable status, ocean sunfish are among the most prolific breeders known. A single female can produce roughly 300 million eggs \u2014 one of the highest reproductive outputs among vertebrates, according to the\u00a0NOAA.<\/p>\n

\u201cSo sad to see that she died, but her death is not in vain,\u201d NECWA officials said.<\/p>\n

NECWA said researchers collected data and tissue samples, along with photographs documenting the tragic scene, to share with scientists worldwide and help answer basic questions about ocean sunfish\u00a0biology\u00a0and ecology.<\/p>\n","protected":false},"excerpt":{"rendered":"A massive\u00a0ocean sunfish, estimated to weigh more than 900 pounds, was found stranded on a Cape Cod\u00a0beach\u00a0earlier this…\n","protected":false},"author":2,"featured_media":851644,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[51],"tags":[17756,13369,18211,149,2001,79,201],"class_list":["post-851643","post","type-post","status-publish","format-standard","has-post-thumbnail","category-wildlife","tag-beaches","tag-cape-cod","tag-fish","tag-lifestyle","tag-massachusetts","tag-science","tag-wildlife"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/851643","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=851643"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/851643\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/851644"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=851643"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=851643"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=851643"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
