This lets them easily move around in all directions. That is to say, by sucking water and then pushing it back out quickly through a narrow siphon. HOW DO THEY MOVE AROUND?īoth of them move by means of jet propulsion. Both species die soon after going through the reproductive cycle. Squids exhibit a different reproductive behavior they mate in groups and deposit clusters of eggs in algae. The female lays eggs, which she guards until they hatch 30 days to one year later, depending on the species.
Male octopuses use the hectocotylus, a specialized arm for transferring their sperm to the mantle cavity of a sexually mature female. Although the average octopus is 12 in–36 in (30 cm–90 cm), they can grow to up to 4.3 feet (1.3 m)! HOW DO THEY REPRODUCE? By contrast, octopuses-with a life span of approximately 5 years-grow to be quite large.
Most squids measure less than 12 in (30 cm). Another piece of information that helps distinguish between the two animals is that most squids are smaller than octopuses, with the exception of giant squids.
