They also have a round black patch around their eye and black lips that some people think makes them appear to be smiling. Sadly, they don\u2019t have a lot to smile about.<\/p><h2 class=\"wp-block-heading\">Where do vaquitas live?<\/h2><p>Vaquitas are endemic (only found) in one small, 2,235km<sup>2<\/sup> area in the north of the Gulf of California (Sea of Cortez), off Mexico. This is the most restricted range of any whale, dolphin or porpoise. They live in shallow, turbid waters.<\/p><figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\"><iframe loading=\"lazy\" title=\"Extinction alert issued over endangered vaquita porpoise - BBC News\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/x4aPE10RLwc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\"\/><\/div><\/figure><h2 class=\"wp-block-heading\">How big are vaquitas?<\/h2><p>Vaquitas are around 1.5 metres long and weigh up to 68kg<\/p><h2 class=\"wp-block-heading\">What does Vaquita mean?<\/h2><p> Vaquita is Spanish for \u2018little cow\u2019.<\/p><h2 class=\"wp-block-heading\"><strong>What <\/strong>do vaquitas eat?<\/h2><p>Like a lot of other porpoises, the vaquita\u2019s diet consists of small fish, squid and crustaceans.\u00a0<\/p><h2 class=\"wp-block-heading\"><strong>How do they track their prey?<\/strong><\/h2><p>Vaquitas use <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/what-is-echolocation\">echolocation<\/a>. This is a technique used by many animals, including toothed whales, dolphins and porpoises, which involves making high-pitched clicks that bounce off objects around them. The echo that comes back gives the vaquita information about its surroundings and enables it to locate prey.<\/p><p\/><h2 class=\"wp-block-heading\"><strong>How many teeth does the vaquita have? <\/strong><\/h2><p>Vaquitas have 26-32 teeth. Once lost they are not replaced.<\/p><p\/><h2 class=\"wp-block-heading\"><strong>Do they form pods<\/strong>?<\/h2><p>They are generally seen alone or in pairs but have been observed in small groups. However, the population now numbers only around 10 individuals.<\/p><h2 class=\"wp-block-heading\">How long do Vaquita live for?<\/h2><p>A vaquita&#8217;s lifespan is estimated to be around 20 years.<\/p><p\/><h2 class=\"wp-block-heading\"><strong>What sounds does the vaquita make?<\/strong><\/h2><p>Vaquitas produce intense, narrow-band, high-frequency echolocation clicks, like other porpoises (ranging from 122-150kHz). They rely on <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/what-is-echolocation\">echolocation<\/a> to navigate, communicate and detect prey. Also, like their harbour porpoise cousins, they make a puffing noise as they surface to breathe, which sounds a bit like pig snorts \u2013 the reason porpoises used to be commonly known as \u2018puffing pigs\u2019.<\/p><p\/><h2 class=\"wp-block-heading\"><strong>Do they have natural predators?<\/strong><\/h2><p>Large species of sharks and possibly <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/marine-animals\/facts-about-orcas\">orcas<\/a>. <\/p><p>Vaquitas have distinctive colouring (with a dark back and pale underside) providing them with natural camouflage. They are shy and elusive, which may also help them evade predators<\/p><h2 class=\"wp-block-heading\"><strong>What are the main threats to the vaquita?<\/strong><\/h2><p>Vaquitas are critically endangered. Bycatch (accidentally entanglement) in fishing nets has almost wiped vaquitas out. Although the Mexican government has now banned the static nets that kill them, illegal gillnet fishing for totoaba is still rife in the vaquitas\u2019 home, and discarded nets also pose a significant risk to these little porpoises.<\/p><h2 class=\"wp-block-heading\">Why are they on the brink of extinction?<\/h2><p>The vaquita, the world&#8217;s rarest marine mammal, is on the edge of extinction. In 1997, there were estimated to be around 600 vaquitas. Ninety per cent of the population was lost between 2011 and 2016 alone. The plight of cetaceans \u2013whales, dolphins and porpoises \u2013 as a whole is exemplified by the rapid decline of the vaquita in Mexico, now with only around 10 individuals remaining as a result of unsustainable and illegal fishing.<\/p><p>In his column <a href=\"https:\/\/www.discoverwildlife.com\/people\/mark-carwardine-notre-dame-fire\">Mark Carwardine asks why more wasn&#8217;t done to save the vaquita<\/a>.<\/p><p\/><h2 class=\"wp-block-heading\"><strong>What is the scientific name?<\/strong><\/h2><p><em>Phocoena sinus<\/em><\/p><h2 class=\"wp-block-heading\"><strong>What is the classification?<\/strong><\/h2><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Kingdom: Animalia<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Phylum: Chordata<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Class: Mammalia<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Order: Artiodactyla<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Infraorder: Cetacea<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Family: Phocoenidae<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Genus: Phocoena<\/p><p>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Species: P. sinus<\/p><p\/><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/><p>Main image @ Paula Olson, NOAA, Public domain, via Wikimedia Commons<\/p> <\/body><\/html>\n<hr class=\"no-tts wp-block-separator\"\/>","protected":false},"excerpt":{"rendered":"<p>Learn all about the vaquita, the world&#8217;s smallest and rarest cetacean in this expert guide from Whale and Dolphin Conservation <\/p>\n","protected":false},"author":24,"featured_media":35902,"template":"","categories":[1],"acf":{"readingTimeMinutes":"3"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction.jpg",1811,890,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction-300x147.jpg",300,147,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction-768x377.jpg",768,377,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction-1024x503.jpg",800,393,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction-1536x755.jpg",1536,755,true],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/44\/2024\/02\/discover-the-rare-vaquita-a-tiny-porpoise-on-the-brink-of-extinction.jpg",1811,890,false]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcwildlife\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"Learn all about the vaquita, the world's smallest and rarest cetacean in this expert guide from Whale and Dolphin Conservation","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/rss_feed\/35901"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/rss_feed"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/types\/rss_feed"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/users\/24"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/media\/35902"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/media?parent=35901"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcwildlife\/wp-json\/wp\/v2\/categories?post=35901"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
