Dol­phin be­hav­iour ex­plained

World of Animals - - Watch Wild Dol­phins -

Por­pois­ing

This be­hav­iour in­volves a dol­phin al­ter­nat­ing be­tween be­ing un­der­wa­ter and fly­ing through the air. The dol­phin leaves and en­ters the wa­ter head­first, which helps the an­i­mal move quickly with­out con­stantly bat­tling wa­ter re­sis­tance.

Spy-hop­ping

Dol­phins some­times pop up ver­ti­cally head­first out of the wa­ter be­fore then bob­bing back down again. This be­hav­iour gives the dol­phin a good look around at what’s go­ing on, and the an­i­mal may even do this to get a bet­ter look at the hu­mans watch­ing it.

Breach­ing

This en­tails leav­ing the wa­ter com­pletely and land­ing with a splash. This be­hav­iour may help scratch an itch, dis­lodge par­a­sites or ac­cel­er­ate a dol­phin’s nat­u­ral skin ex­fo­li­a­tion. On the other hand, maybe it’s just bril­liant fun. No­body knows for sure.

Bow rid­ing

Dol­phins seem to en­joy swim­ming in the pres­sure wave cre­ated by a mov­ing ves­sel. This dis­turbed wa­ter may be eas­ier for the dol­phins to travel through, there­fore re­duc­ing the amount of ef­fort that is re­quired for them to move for­wards.

Tail slap­ping

As the name sug­gests, this be­hav­iour in­volves a dol­phin beat­ing its tail on the wa­ter’s sur­face. This could have a com­mu­nica­tive pur­pose, but some dol­phin species use this method to stun nearby fish to make them eas­ier to catch.
