Reproduction
Multiple eggs at various developmental stages have been found in dissected females, meaning they presumably lay eggs all year long instead of having a breeding season.
The male Dumbo octopus has an enlarged segment on one of his arms which is used to transfer spermatophores (packets of sperm) into the female's mantle cavity. Once transferred, the packets will rupture so the sperm can fertilize the eggs. The female will then lay the eggs underneath rocks and shells and leave them to fend for themselves.
