Kamar yadda motsa cuttlefish?

Misalan jet propulsion ne yadu wakilci a fauna. Cuttlefish - cephalopod da ciwon musamman mazurari wanda aka sanya a gaban na jiki. Therethrough (da kuma ta hanyar ƙarin kaikaice tsaguwa), da ruwa gudana a cikin dabba jiki a cikin gill kogo.

Misalai jet propulsion jikinsu. squid

A musamman halitta na jiki na da squid. A gaskiya a cikin yanayin da tsarin ƙunshi wani iko jet engine, wanda yana da wani kyakkyawan ingancinsu. Wannan wakilin fauna daga cikin tekuna da kuma teku, wani lokacin yana raye a mafi zurfin da ya kai babban rabbai. Ko da dabba ta jiki yayi kama da roka da ta siffofi.
