Za vrijeme vožnje trajektom, imali smo zadovoljstvo vidjeti jato dupina koji skaču izvan mora, a neki su uspjeli i napraviti lijepe fotografije.

Stoga na prvu možda naizgled smiješno pitanje, ali nitko nije znao točan odgovor: zašto dupini uopće skaču?
Dean J., Split

Pitanje je sasvim na mjestu, jer su vjerojatno mnogi vidjeli dupine koji skaču, a da ne govorimo o atrakcijama iz vodenih parkova, gdje se mogu vidjeti kako skaču kroz kolutove, okreću se u zraku ili balansiraju na svome repu iznad površine.

Dupini inače mogu skakati i preko osam metara u visinu, ali na pitanje zašto skaču, nema jednoznačnog odgovora. Postoji nekoliko znanstvenih teorija koje upućuju na više razloga.

Jedna upućuje na dupine kao visokointeligentne morske sisavce koji se zapravo vole igrati, te često skaču iz proste zabave. Ipak, nije samo zabava glavni cilj, jer igranjem izoštravaju svoje osjete i time se stalno unaprjeđuju.

Nadalje, kako dupini komuniciraju zvukovima i kretanjima, skakanje iznad površine jedan je vid komunikacije, kako sa suprotnim spolom, tako i ostalim pripadnicima jata, jer svi mogu interpretirati zvukove koji nastaju različitim pljuskanjem po površini mora.

Time dodatno i ostalima pokazuju svoju snagu i sposobnost. Nadalje, skakanjem povećavaju svoje vidno polje okoline, jer onda vide i sve što se događa oko njih na površini.

Također, postoji teorija da skakanjem štede energiju, jer je otpor zraka manji od mora, a i da se skakanjem rješavaju parazita na koži.

Uglavnom, očito je da postoji više razloga takvom ponašanju, što se od dupina moglo i očekivati.

Za vrijeme vožnje trajektom, imali smo zadovoljstvo vidjeti jato dupina koji skaču izvan mora, a neki su uspjeli i napraviti lijepe fotografije.

Stoga na prvu možda naizgled smiješno pitanje, ali nitko nije znao točan odgovor: zašto dupini uopće skaču?
Dean J., Split

Pitanje je sasvim na mjestu, jer su vjerojatno mnogi vidjeli dupine koji skaču, a da ne govorimo o atrakcijama iz vodenih parkova, gdje se mogu vidjeti kako skaču kroz kolutove, okreću se u zraku ili balansiraju na svome repu iznad površine.

Dupini inače mogu skakati i preko osam metara u visinu, ali na pitanje zašto skaču, nema jednoznačnog odgovora. Postoji nekoliko znanstvenih teorija koje upućuju na više razloga.

Jedna upućuje na dupine kao visokointeligentne morske sisavce koji se zapravo vole igrati, te često skaču iz proste zabave. Ipak, nije samo zabava glavni cilj, jer igranjem izoštravaju svoje osjete i time se stalno unaprjeđuju.

Nadalje, kako dupini komuniciraju zvukovima i kretanjima, skakanje iznad površine jedan je vid komunikacije, kako sa suprotnim spolom, tako i ostalim pripadnicima jata, jer svi mogu interpretirati zvukove koji nastaju različitim pljuskanjem po površini mora.

Time dodatno i ostalima pokazuju svoju snagu i sposobnost. Nadalje, skakanjem povećavaju svoje vidno polje okoline, jer onda vide i sve što se događa oko njih na površini.

Također, postoji teorija da skakanjem štede energiju, jer je otpor zraka manji od mora, a i da se skakanjem rješavaju parazita na koži.

Uglavnom, očito je da postoji više razloga takvom ponašanju, što se od dupina moglo i očekivati.
