What is the purpose of an octopus siphon and how does it function in the animal's anatomy?
The purpose of an octopus siphon is to expel water from its body, allowing it to move quickly and efficiently. The siphon is a muscular tube located on the underside of the octopus, near its head.

What is a siphon and how does it function on an octopus?
