siphon(o)-

Siphon.

Greek siphōn, pipe.

The siphonapterans are members of an order of insects with sucking mouth parts, comprising the fleas (the name literally means ‘wingless pipe’, from Greek apteros, wingless); siphonophores (Greek pherein, to bear) are members of an order of colonial marine coelenterates that includes the Portuguese man-of-war; a siphonostele is a type of plant whose stems contain a hollow tube of tissue. Siphuncle, a tube connecting the chambers of a nautilus, is from the Latin diminutive siphunculus, a small tube, rather than from Greek.
