However, close examination of medusae has revealed that the arrangement and developmental order of the tentacles obey a mathematical rule. Here, we show that medusa jellyfish adopt the best strategy to achieve the most uniform distribution of a variable number of tentacles. The observed order of tentacles is a real-world example of an optimal hashing algorithm known as Fibonacci hashing in computer science.<\/jats:p>","DOI":"10.1038\/srep27347","type":"journal-article","created":{"date-parts":[[2016,6,7]],"date-time":"2016-06-07T09:10:44Z","timestamp":1465290644000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Optimal hash arrangement of tentacles in jellyfish"],"prefix":"10.1038","volume":"6","author":[{"given":"Takuya","family":"Okabe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin","family":"Yoshimura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2016,6,7]]},"reference":[{"key":"BFsrep27347_CR1","first-page":"425","volume":"28","author":"K Kinoshita","year":"1916","unstructured":"Kinoshita, K.
