No veterinarian was called and believe me, it wasn&#8217;t pretty. The muzzle of a horse is extremely sensitive to begin with and this one probably had over a hundred quills in it. I&#8217;ll just say the restrained horse was terrified and in great pain with every extraction. I was just a young kid at the time\u00a0and the memory (and the sound)\u00a0is still seared into my brain.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"63341\" data-permalink=\"https:\/\/featheredphotography.com\/blog\/2018\/09\/12\/why-a-snoot-full-of-porcupine-quills-can-be-a-serious-matter\/porcupine-quills-0617-ron-dudley\/\" data-orig-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley.jpg\" data-orig-size=\"900,648\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;5.6&quot;,&quot;credit&quot;:&quot;RON DUDLEY&quot;,&quot;camera&quot;:&quot;Canon EOS 7D&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1536681544&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;70&quot;,&quot;iso&quot;:&quot;800&quot;,&quot;shutter_speed&quot;:&quot;0.0125&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"porcupine quills 0617 ron dudley\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley.jpg\" class=\"aligncenter wp-image-63341 size-full\" title=\"porcupine-quills-0617-ron-dudley\" src=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley.jpg\" alt=\"\" width=\"900\" height=\"648\" srcset=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley.jpg 900w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley-300x216.jpg 300w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley-768x553.jpg 768w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley-150x108.jpg 150w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/porcupine-quills-0617-ron-dudley-400x288.jpg 400w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>And these are the source of all that misery.\u00a0I took these quills from the dead, stinky porcupine at the &#8220;porcupine bush&#8221; where I&#8217;ve been photographing birds for the last few weeks. Quills are modified hairs and each porcupine has about 30,000 of them covering their entire body except for their underbelly, face and feet. They&#8217;re incredibly light, so light you can&#8217;t even feel the weight of a\u00a0bunch of them in your hand. And each quill has 700-800 tiny one-way\u00a0barbs at its tip that make the quill much more difficult (and painful)\u00a0to pull out of the victim than was required when they went in.<\/p>\n<p>Scientists\u00a0have recently discovered that porcupine quills are much\u00a0sharper than we thought they were. Following is a description of their research results from the online site &#8220;Science&#8221;. It&#8217;s a bit lengthy but I highly recommend it. I think it&#8217;s fascinating, partly because the results were so unexpected.<\/p>\n<ul>\n<li><em>&#8220;The researchers took barbed porcupine quills and plunged them into samples of pig skin, measuring how much force it took to pierce the flesh and then how much force was required to extricate the quill. The team then performed the same tests using quills whose barbs they had sanded off. They also tested an African porcupine&#8217;s quills (which naturally have no barbs) and an 18-gauge hypodermic needle, which is approximately the same diameter as a quill from the North American porcupine.<\/em><\/li>\n<li><em>To the scientists&#8217; surprise, barbed quills required approximately half the penetration force of the barbless quills\u2014either those naturally barbless or those sanded clean\u2014and only 56% of the force needed for the hypodermic needle to breach the skin. Computer models suggest that the barbs ease the quill&#8217;s penetration by concentrating force along the edges of the barbs, similar to how the serrations on a knife blade make cutting meat easier.<\/em><\/li>\n<li><em>Barbs render a quill about four times harder to pull out once they&#8217;re embedded, the team found. The barbs at the tip of the quill were most effective at resisting removal. In fact, the barbs located within 1 millimeter of the tip contributed about half of the pull-out resistance\u2014possibly because the flesh more tightly surrounded the tip than it did the rest of the quill.&#8221;<\/em><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>While I was trying to arrange the quills in my fingers for the photo\u00a0above I tried to be very careful but I stuck myself several times and they didn&#8217;t come out of my skin easily. If they had gone in deeper than just my skin I can only imagine how difficult they would have been to pull out.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"63340\" data-permalink=\"https:\/\/featheredphotography.com\/blog\/2018\/09\/12\/why-a-snoot-full-of-porcupine-quills-can-be-a-serious-matter\/moose-1041-ron-dudley1\/\" data-orig-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1.jpg\" data-orig-size=\"900,801\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;8&quot;,&quot;credit&quot;:&quot;RON DUDLEY&quot;,&quot;camera&quot;:&quot;Canon EOS 7D&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;1343979930&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;500&quot;,&quot;iso&quot;:&quot;500&quot;,&quot;shutter_speed&quot;:&quot;0.016666666666667&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"moose-1041-ron-dudley1\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1.jpg\" class=\"aligncenter wp-image-63340 size-full\" title=\"moose-1041-ron-dudley\" src=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1.jpg\" alt=\"\" width=\"900\" height=\"801\" srcset=\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1.jpg 900w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1-300x267.jpg 300w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1-768x684.jpg 768w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1-150x134.jpg 150w, https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1-400x356.jpg 400w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/a><\/p>\n<p>Several years ago I photographed this cow moose in the Uinta Mountains. From a distance I thought she was trying to eat something white because I could see her tongue maneuvering around the &#8220;white stuff&#8221; but through my lens it was instantly obvious that she&#8217;d been quilled. The poor cow had many days of misery ahead of\u00a0her before her body\u00a0would dissolve\u00a0the embedded parts of the quills. One danger is infection but there&#8217;s another. If the quills are embedded in areas of loose skin (such as the neck of a dog for example) the barbs sometimes make the quills move\u00a0deeper into the body with very serious consequences. After this\u00a0photo was taken I was somewhat relieved to see her browsing in the willows &#8211; she was actually able to eat.<\/p>\n<p>One last porcupine story. My uncle Floyd and family (their farm adjoined ours)\u00a0had a smallish white\u00a0dog named Toby who was what I called a &#8220;grouchy sumbitch&#8221; and that was when he was having a good day. When he wasn&#8217;t he could be truly nasty, although I always had a soft spot for him. Toby was small but fearless and a relentless killer of &#8220;gophers&#8221;, skunks and even the occasional weasel when he could catch one and he showed no hesitation with porcupines &#8211; he just\u00a0plowed right in and took them on.\u00a0Needless to say we had to pull quills out of him more than once.<\/p>\n<p>With\u00a0Toby there was only one way to do it. Floyd had an old piece of stiff, discarded carpet that he kept for just that purpose, When we could\u00a0finally catch Toby (he knew what was coming)\u00a0it took three of us to roll him up tightly, very tightly,\u00a0in the carpet with only\u00a0his face\u00a0sticking out. Then one of us would grab the pliers and we&#8217;d start\u00a0pulling them out.\u00a0Believe me that was one pissed off dog!<\/p>\n<p>When it was over we sometimes didn&#8217;t see\u00a0him again for days, though his food always disappeared from the porch. But eventually he always forgave us in his own time and in his own\u00a0Toby way. To this day I always think of\u00a0him as a little white grizzly bear.<\/p>\n<p>Ron<\/p>\n<p><em>PS &#8211; If you&#8217;re interested here&#8217;s a link to an older post I published about a <a href=\"https:\/\/featheredphotography.com\/blog\/2017\/11\/27\/a-porcupine-story\/\" target=\"_blank\" rel=\"noopener\">porcupine incident<\/a> involving author Terry Tempest Williams and myself.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8220;Don&#8217;t mess with Porky&#8221; was one of the early lessons I learned growing up on the Montana farm.<\/p>\n<p> <a class=\"continue-reading-link\" href=\"https:\/\/featheredphotography.com\/blog\/2018\/09\/12\/why-a-snoot-full-of-porcupine-quills-can-be-a-serious-matter\/\"><span>Continue reading<\/span><i class=\"crycon-right-dir\"><\/i><\/a> <\/p>\n","protected":false},"author":2,"featured_media":63340,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[3,334,1493,839],"tags":[2777,220,786,790,791,795,311],"class_list":["post-63339","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-antelope-island","category-birds","category-montana-favorite-locations","category-porcupine-mammals","tag-barbs","tag-montana-2","tag-moose","tag-porcupine","tag-quill","tag-terry-tempest-williams","tag-utah-2"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2018\/09\/moose-1041-ron-dudley1.jpg","jetpack_shortlink":"https:\/\/wp.me\/p1zzJh-gtB","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/63339","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/comments?post=63339"}],"version-history":[{"count":1,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/63339\/revisions"}],"predecessor-version":[{"id":165108,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/posts\/63339\/revisions\/165108"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media\/63340"}],"wp:attachment":[{"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/media?parent=63339"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/categories?post=63339"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/featheredphotography.com\/blog\/wp-json\/wp\/v2\/tags?post=63339"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
