hey everyone! ocean conservation and marinelife expert jaclyn friedlander here and today we are going to talk about a very interestingsymbiotic relationship between goby fish and pistol shrimp. a symbiotic relationship in biology is whentwo different species live together to the benefit of one or both creatures. in thiscase, both the goby and the pistol shrimp
Chek Jawa, benefit from living together. before we can learn how these two animalswork together, we need to know a little bit about each one individually. the pistol shrimpor snapping shrimp is considered to be one of the loudest creatures on earth. they haveone modified claw that they use as a defense
mechanism against predators. the snappingsound that their modified claw makes is louder than a gunshot and can break a glass jar!the sound is actually not made by the claw hitting together as scientists first believed.the sound is created by a bubble that is formed when a shrimp snaps its claw. the bubble cantravel up to 68 miles per hour and when the bubble pops, it pops with such force thatthe sound is created. a short burst of light is also created when a shrimp snaps but thelight happens so quickly it is invisible to the naked eye. one of the first questions i wondered wheni found out about snapping shrimp is what happens if the shrimp loses it�s snappingclaw? the answer is very interesting. like
many other animals that have the ability toregenerate or regrow a lost body part, a new snapping claw will grow back. the thing thatis unique about the snapping shrimp, though, is that they reverse claw. that means thatto make the process of their defense claw growing back take less time, their smallerclaw grows into their snapping claw and a new regular claw grows back where their lostsnapping claw once was. i find snapping shrimp so interesting thata snapping shrimp is a character in the third friends with fins book, which is a bedtimebook that will be published soon. in the mean time, if you don't have the first two friendswith fins books, you can get them by clicking on the card.
now that we know about snapping shrimp, let'stalk about goby fish. gobies come from one of the largest fish families, known as gobiidae.there are over 2000 different species of goby fish that are found all over the world bothin the salty water of the ocean as well as in the brackish water found in estuaries.their habitats range from tide pools to coral reefs to sea grass meadows. generally gobiesare bottom dwellers and range in size from one to four inches. they don't have theirown defense mechanism to defend against predators and that's where the symbiotic relationshipwith snapping shrimp comes in handy! snapping shrimp are almost blind, so theycan't see to hunt and can't see when predators are approaching. because of this, they usetheir antenna to stay connected to watchmen
gobies. when the goby senses danger, it wigglesits tales to alert the snapping shrimp to snap! if danger is within sticking distance,they both dart into the burrow they live in together that is often built by the snappingshrimp. so in return for help with defense, the goby provides eyes for the shrimp! this is a photo by mark strickland of a snappingshrimp and a blue spotted watchman goby. it is the perfect illustration of how these twoanimals live together. as you can see, the shrimp is using its antenna to take signalsfrom the goby and the goby is standing guard. thank you to mark strickland for sharing yourpistol shrimp/goby photos for this video. a link to his website is in the info sectionbelow if you want to see many more amazing
