Caudal luring

<h2 id="mimicry">Mimicry</h2> <p>The tail of a species may serve various functions, such as aggression, defense and feeding.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> Caudal luring behavior was first recorded in 1878<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> and is an instance of <a href="/facts/Aggressive_mimicry/qzV3qeab">aggressive mimicry</a>.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> Predators attract their prey by moving their caudal section to mimic a small animal, such as a worm, and attract prey animals.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> The prey is intrigued by caudal movement and will investigate assuming it is their own prey, and the predator will strike.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> </p> <h2 id="species">Species</h2> <h3>Snakes</h3> <p>Caudal luring behavior is found in over 50 different snake species.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> It is most common in <a href="/facts/Boidae/0Y5FKhM2">boas</a>, <a href="/facts/Pythonidae/U3T63eYB">pythons</a>, <a href="/facts/Tropidophiidae/602P3PuE">tropidophiids</a>, <a href="/facts/Colubridae/WB4RqbEF">colubrids</a> and <a href="/facts/Elapidae/D6lc1jrB">elapids</a> of the genus <i><a href="/facts/Common_death_adder/Hnv7UQ8q">Acanthophis</a></i>, and the most evident in vipers and pit vipers, especially in rattlesnakes.<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a><a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a><a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> When the snake is foraging, it waits coiled up with its tail elevated and visible, wiggling around in a way that mimics a smaller animal and captures the attention of its prey.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> Once the prey is in striking range, the snake attacks.<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> An immobile tail does not attract prey, confirming that it is the moving lure that tricks and attracts prey.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> Caudal luring behavior is only elicited when prey are nearby.<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a> Due to the tail resembling a writhing caterpillar and another worm-like insect larvae, the tail of the snake is often referred to as a vermiform.<a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a> Some species have developed elaborate lures to mimic a specific animal, such as the <a href="/facts/Spider-tailed_horned_viper/x2um9Xfs">spider-tailed horned viper</a>, which employs a highly modified tail to mimic a spider's form and locomotion.<a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a> </p><p>Of the snakes that practice the caudal luring behavior, 80% are juvenile.<a class="footnote-ref" id="fnref:22" href="#fn:22"><sup>22</sup></a> The tails of juvenile snakes are typically conspicuously colored and fade to become more similar to the rest of the body with age.<a class="footnote-ref" id="fnref:23" href="#fn:23"><sup>23</sup></a><a class="footnote-ref" id="fnref:24" href="#fn:24"><sup>24</sup></a> This has been theorized to be an explanation for why caudal luring is most successful and prevalent in juveniles.<a class="footnote-ref" id="fnref:25" href="#fn:25"><sup>25</sup></a> However, this explanation has been contested.<a class="footnote-ref" id="fnref:26" href="#fn:26"><sup>26</sup></a> Experimental manipulation of <i><a href="/facts/Sistrurus_miliarius/QkuaPCN3">Sistrurus miliarius</a></i>’ tail color to make the tail match the rest of the juvenile's body revealed no significant difference in foraging success.<a class="footnote-ref" id="fnref:27" href="#fn:27"><sup>27</sup></a> Another theory for juvenile success has been that their small tails are more effective lures compared to an adult's larger tail. Studies have confirmed that a smaller lure is more effective in attracting prey, as it is closer to the size of the worm-like prey.<a class="footnote-ref" id="fnref:28" href="#fn:28"><sup>28</sup></a> </p> <h3>Sharks</h3> <p>Caudal luring also occurs in sharks, most common among <i><a href="/facts/Alopias_vulpinus/QzALwkbD">Alopias vulpinus</a></i>, <i><a href="/facts/Alopias_superciliosus/eH11TBWp">Alopias superciliosus</a></i> and <i><a href="/facts/Alopias_pelagicus/qU952KKt">Alopias pelagicus</a>.</i><a class="footnote-ref" id="fnref:29" href="#fn:29"><sup>29</sup></a> Their tails are all of varying shapes and sizes, but are all used to attract and immobilize prey.<a class="footnote-ref" id="fnref:30" href="#fn:30"><sup>30</sup></a> Evidence of caudal luring comes from their diet, which consists largely of small schooling fishes which are susceptible to the luring strategy.<a class="footnote-ref" id="fnref:31" href="#fn:31"><sup>31</sup></a> </p><p>The tasselled wobbegong <i>(<a href="/facts/Eucrossorhinus_dasypogon/mvDzUmRv">Eucrossorhinus dasypogon</a>),</i> a carpet shark, has a caudal fin that resembles a small fish with a small dark eyespot.<a class="footnote-ref" id="fnref:32" href="#fn:32"><sup>32</sup></a> The caudal fin is waved slowly to attract and immobilize prey.<a class="footnote-ref" id="fnref:33" href="#fn:33"><sup>33</sup></a><a class="footnote-ref" id="fnref:34" href="#fn:34"><sup>34</sup></a> </p> <h3>Eels</h3> <p>Caudal luring is suspected to occur in the family <i><a href="/facts/Saccopharyngidae/Q2Ks9zk4">Saccopharyngidae</a></i>.<a class="footnote-ref" id="fnref:35" href="#fn:35"><sup>35</sup></a> The caudal organs of these eels are <a href="/facts/Bioluminescence/IlzgyV4E">luminous</a> and equipped with filaments that would facilitate luring.<a class="footnote-ref" id="fnref:36" href="#fn:36"><sup>36</sup></a> These eels prey solely on relatively large fishes, suggesting the use of a lure to trap their prey.<a class="footnote-ref" id="fnref:37" href="#fn:37"><sup>37</sup></a> </p> <h2 id="evolution">Evolution</h2> <p>It has been suggested that caudal luring was involved in the evolution of the <a href="/facts/Tail_vibration/2MuWz50P">tail vibration</a> rattle of <a href="/facts/Rattlesnake/LHojq55U">rattlesnakes</a>, a <a href="/facts/Aposematism/Npct7Xz1">warning signal</a> and a way of auditory communication, though this has been challenged.<a class="footnote-ref" id="fnref:38" href="#fn:38"><sup>38</sup></a><a class="footnote-ref" id="fnref:39" href="#fn:39"><sup>39</sup></a><a class="footnote-ref" id="fnref:40" href="#fn:40"><sup>40</sup></a><a class="footnote-ref" id="fnref:41" href="#fn:41"><sup>41</sup></a> Prey luring, in general, is confounded by false interpretation, as the wiggling of an appendage could have other behavioral meanings including aposematism, defense, or nervous release, and experimental evidence has been weak.<a class="footnote-ref" id="fnref:42" href="#fn:42"><sup>42</sup></a><a class="footnote-ref" id="fnref:43" href="#fn:43"><sup>43</sup></a><a class="footnote-ref" id="fnref:44" href="#fn:44"><sup>44</sup></a> </p><p>Caudal luring is thought to have evolved from a caudally localized intention movement<a class="footnote-ref" id="fnref:45" href="#fn:45"><sup>45</sup></a> (a behavior derived from <a href="/facts/Animal_locomotion/trhhYTVR">locomotor</a> movements).
