Coconut crabs produce “tapping-like sounds” to communicate with each other and they make a variety of clicking noises during their entire mating sessions.
Wikimedia CommonsScientists discovered that coconut crabs make “ tapping - like sounds ” to pass along , particularly during sex activity .
Turns out humans are n’t the only animals that talk during sexual activity . A new studypublished inZoologyfound that coconut palm crabs — those “ monster ” crabs that are strong enough to break a seabird ’s bones — are quite talky during their entire union sessions .
According toLive Science , the study examine the weird “ rap - like strait ” coconut Phthirius pubis are have it away to make . How the crabs produced the clicking sounds had been a mystery story up until now .
Wikimedia CommonsScientists discovered that coconut crabs create “tapping-like sounds” to communicate, especially during sex.
Using X - rays and digital recording , researchers were able to determine that the tapping sound were produced through vacillate thin appendage known as scaphognathites , which reap air into the Cancer ’ lungs .
When the thin appendages vibrate , they waver against the hard plates in the crabs ’ gill channels , which is what produce the “ tapping ” disturbance . Not only that , investigator also get that crabs could produce multiple sound that varied in frequency and intervals when the shaking speed modify .
This creates singular level of communication when the Cancer are “ sing ” to each other . But the study also found that coconut Cancer the Crab do n’t just use these tapping noises in their even day - to - day communications . They also use it quite a bit during sexual activity .

inquiry on mating cocoanut Phthirius pubis showed that they create noises before , during , and after their mating session . Furthermore , the noises that the crabs produce sounds different at each stage of their union .
“ Although the relationship between the sounds and action mechanism was not clarify in this study , it is probable that the pediculosis pubis deliberately produce various eccentric of sounds for dissimilar occasions , ” the study assessed .
While the aquatic spiny lobster ( Procambarus clarkii ) is sleep with to make sounds using a similar structure , coconut crabs are the only land crustaceans known to do this , the source reported .
Coconut crabs(Birgus latro ) are the largest nation crabs on Earth . They matter up to nine punt with a branch span of three feet .
Interestingly , unlike other crab species , these giant beach - dwellersare ineffective to swim , which prevents them from island - hopping around the Indian Ocean . So some island naturally harbour high populations of cocoanut crabs than others .
As their name suggests , their chief food source is coconuts , which the Cancer can easily cut into using their thick , sharp claw . Being fit out with such sturdy peter , coconut palm crabs have been make love to hunt meat , too , such as seabirds . In some cases , they even cannibalize the corpses of their own .
Biologist Mark Laidre trace the coconut crab ’s menacing mode of attack after he successfully captured a cocoa palm crab down a dead bird on the beach one dark .
“ I observed a coconut tree crab onslaught and kill an adult cherry-red - footed dope , ” said Laidre . “ The booby had been sleeping on a low - lie branch , less than a metre up the Sir Herbert Beerbohm Tree . The crabmeat slowly climbed up and snaffle the booby ’s wing with its chela , breaking the bone and get the booby to fall to the ground . ”
Despite their furious show , coconut Crab seldom hurt human being . So far , there ’s been only one recorded possible action of coconut pediculosis pubis feeding on a human corpse , which many believed belong to the long - lost female pilotAmelia Earhart .
But this hardly paint the monster Crab as deadly predators .
“ They ’re not belligerent . They ’re curious , ” Laidre toldNational Geographic . “ They ’re not come and jumping and trying to attack you . Coconut crabs more should fear man . ”
There ’s still much we have yet to empathise about these magnificent beach giants . Hopefully , we ’ll soon be able-bodied to crack the computer code of their unique communication patterns and study more about their specie .
