What was once a thriving ecosystem filled with sharks, seals and smaller prey has, in many areas, gone quiet.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">&#8220;At one point, we were seeing 250 to 300 great whites a year,&#8221; professional shark photographer Chris Fallows told the outlet. &#8220;Today, you would see nothing.&#8221;<\/p>\n<p><img alt=\"Great white sharkCredit: Getty\" loading=\"lazy\" width=\"960\" height=\"640\" decoding=\"async\" data-nimg=\"1\" class=\"rounded-lg\" style=\"color:transparent\" src=\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2026\/04\/1776224472_915_08d07c6bcd21ea282a227a1f7e4596ad.jpeg\"\/><\/p>\n<p>Great white shark<br \/>Credit: Getty<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The disappearance has sparked a debate within the scientific community, with two leading theories emerging: one pointing to whales, the other to humans.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Marine biologist Alison Kock, who has studied the Cape Town region for years, began investigating after great white shark carcasses started appearing in 2015 with what she described as &#8220;surgical&#8221; wounds. Eventually, necropsies confirmed a surprising predator: orcas.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">The killer whales were <a href=\"https:\/\/people.com\/lone-orca-whale-spotted-killing-great-white-shark-8603934\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:targeting great white sharks;elm:context_link;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;targeting great white sharks&quot;}\" class=\"link \">targeting great white sharks<\/a> for the species&#8217; nutrient-rich livers. Two male orcas, nicknamed Port and Starboard, were even observed hunting sharks in pairs, an unusual behavior that researchers believe may be spreading.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Kock believes the presence of these highly intelligent hunters has driven great whites out of the area.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">&#8220;It&#8217;s the fear of predation,&#8221; she explained, describing how sharks, not accustomed to being hunted, may have fled to safer waters. However, not all marine experts agree.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Marine biologist Enrico Gennari and Fallows argue the decline began before the orcas appeared, pointing instead to human activity. They cite commercial fishing practices that deplete the sharks&#8217; food supply, along with shark nets and baited hooks designed to protect swimmers \u2014 methods that can kill more than 20 great whites a year.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\"><strong>Never miss a story \u2014 sign up for <\/strong><a class=\"link \" href=\"https:\/\/people.com\/people-news-daily-newsletter-sign-up-8692701\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:PEOPLE&#039;s free daily newsletter;elm:context_link;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;PEOPLE&#039;&quot;}\"><strong>PEOPLE&#8217;s free daily newsletter<\/strong><\/a><strong> to stay up-to-date on the best of what PEOPLE has to offer\u200b\u200b, from celebrity news to compelling human interest stories.\u00a0<\/strong><\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">&#8220;Shark longlining is undoubtedly robbing the great white sharks of food,&#8221; Fallows highlighted. The stakes, experts warn, go far beyond one species. Great whites play a critical role in maintaining balance in ocean ecosystems, and their disappearance could signal deeper trouble.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">&#8220;If we lose the white shark in South Africa, we lose a battle for all nature,&#8221; Gennari said.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Read the original article on <a href=\"https:\/\/people.com\/missing-great-white-sharks-spark-debate-over-cause-11949341\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:People;elm:context_link;itc:0;sec:content-canvas\" data-yga=\"{&quot;yLinkElement&quot;:&quot;context_link&quot;,&quot;yModuleName&quot;:&quot;content-canvas&quot;,&quot;yLinkText&quot;:&quot;People&quot;}\" class=\"link \">People<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"NEED TO KNOW Great white sharks have largely disappeared from Cape Town waters over the past decade Scientists&hellip;\n","protected":false},"author":2,"featured_media":435699,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[273],"tags":[140902,193361,39129,18,10177,19,17,144085,133,39149,461],"class_list":["post-435698","post","type-post","status-publish","format-standard","has-post-thumbnail","category-wildlife","tag-cape-town","tag-chris-fallows","tag-coastal-waters","tag-eire","tag-great-white-sharks","tag-ie","tag-ireland","tag-ocean-ecosystems","tag-science","tag-shark-nets","tag-wildlife"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/116406654515858678","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/435698","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=435698"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/435698\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/435699"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=435698"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=435698"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=435698"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
