A female octopus will defend her eggs to the death-literally . In species that live in shallow water, the mother guards a den where her eggs are clustered.

What is the reproductive organ of the octopus?
A Male Octopus’ Reproductive Organ Is One of Its Arms . If you ever get tangled up with a male octopus, be careful which arm you touch. If you reach out to touch the third right arm, it’s more than just his arm, it’s also his reproductive organ, or “manhood”. The octopus uses this specialized arm called a ‘hectocotylus’ to insert ‘spermatophores’ which are packets of sperm, into the female’s mantle cavity for reproduction.
