The Department of Biology\u2019s vast collection of mammal, bird, reptile and fish bones includes more than\u00a0a hundred species, ranging in size from rodents to whales. Associate instructor Frank Logiudice and his colleagues use the specimens to\u00a0help students understand skeletal structure, comparative anatomy, physiology and other topics.[\/lead]<\/p>\n<h2>Here are some lessons Logiudice teaches using the bones of loggerhead sea turtles:<\/h2>\n<p>[divider][\/divider]<\/p>\n<p>The tagging system of this teaching collection relays an array of information about the animal. This skull of a loggerhead sea turtle (<em>Caretta caretta<\/em>) was recovered from a deceased animal that was tagged repeatedly while alive by <a href=\"https:\/\/www.ucf.edu\/research\/\">UCF researchers<\/a> beginning in 1979.<\/p>\n<p>[photo id=&#8221;7783&#8243; title=&#8221;UCF Department of Biology bone collection loggerhead sea turtle tag&#8221; alt=&#8221;UCF Department of Biology bone collection loggerhead sea turtle tag&#8221; width=&#8221;100%&#8221;][\/photo]<\/p>\n<p>[divider][\/divider]<\/p>\n<p>The loggerhead\u2019s beak is composed of keratin and formed through a process similar to the formation of calluses on a human hand. \u201cThe skin is external to the bone, so as the bone is used, the skin will be modified\u00a0to reflect [this],\u201d Logiudice points out. This same process was also seen with triceratops and can currently be observed in birds.<\/p>\n<p>[photo id=&#8221;7784&#8243; title=&#8221;UCF Department of Biology bone collection loggerhead sea turtle beak&#8221; alt=&#8221;UCF Department of Biology bone collection loggerhead sea turtle beak&#8221; width=&#8221;100%&#8221;][\/photo]<\/p>\n<p>[divider][\/divider]<\/p>\n<p>Besides using their large eyes to scan and navigate the ocean, loggerheads also use them to assist with hydration. \u201cInside, there\u2019s a salt gland,\u201d Logiudice says, \u201cand the salt gland lets them drink ocean water, and then they excrete the salt as tears.\u201d<\/p>\n<p>[photo id=&#8221;7782&#8243; title=&#8221;UCF Department of Biology bone collection loggerhead sea turtle skull&#8221; alt=&#8221;UCF Department of Biology bone collection loggerhead sea turtle skull&#8221; width=&#8221;100%&#8221;][\/photo]<\/p>\n<p>[divider][\/divider]<\/p>\n<p>This incomplete juvenile loggerhead carapace shows how the turtle\u2019s bony shell grows over time. \u201cTurtles grow fairly slowly,\u201d says Logiudice. \u201cThey have a slow metabolism, so that still works very well for them; it gives them better protection than cartilage, which is a little softer.\u201d<\/p>\n<p>Since the turtle\u2019s ribs are fused to their shell, \u201cthey can\u2019t breathe like we do, expanding their ribs, so they have to wiggle their flippers around,\u201d Logiudice explains. This wiggling motion helps bring oxygen into their lungs.<\/p>\n<p>[photo id=&#8221;7789&#8243; title=&#8221;UCF Department of Biology bone collection loggerhead sea turtle carapace&#8221; alt=&#8221;UCF Department of Biology bone collection loggerhead sea turtle carapace&#8221; width=&#8221;100%&#8221;][\/photo]<\/p>\n<p>[divider][\/divider]<\/p>\n","protected":false},"featured_media":7746,"template":"","categories":[975],"tags":[287,1002],"class_list":["post-7623","story","type-story","status-publish","has-post-thumbnail","hentry","category-artifact","tag-college-of-sciences","tag-ucf-marine-turtle-research-group","issues-520","issues-fall-2015"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.3 (Yoast SEO v27.7) -
