If a women is a starfish then what term is used for men?

Knoctopus.

Most species of starfish are gonochorous, there being separate male and female individuals. These are usually not distinguishable externally as the gonads cannot be seen, but their sex is apparent when they spawn. Some species are simultaneous hermaphrodites, producing eggs and sperm at the same time and in a few of these, the same gonad, called an ovotestis, produces both eggs and sperm.[29] Other starfish are sequential hermaphrodites. Protandrous individuals of species like Asterina gibbosa start life as males before changing sex into females as they grow older. In some species such as Nepanthia belcheri, a large female can split in half and the resulting offspring are males. When these grow large enough they change back into females.[30]

Each starfish arm contains two gonads that release gametes through openings called gonoducts, located on the central disc between the arms. Fertilization is generally external but in a few species, internal fertilization takes place. In most species, the buoyant eggs and sperm are simply released into the water (free spawning) and the resulting embryos and larvae live as part of the plankton. In others, the eggs may be stuck to the undersides of rocks.[31] In certain species of starfish, the females brood their eggs – either by simply enveloping them[31] or by holding them in specialised structures. Brooding may be done in pockets on the starfish's aboral surface,[32][33] inside the pyloric stomach (Leptasterias tenera)[34] or even in the interior of the gonads themselves.[29] Those starfish that brood their eggs by "sitting" on them usually assume a humped posture with their discs raised off the substrate.[35] Pteraster militaris broods a few of its young and disperses the remaining eggs, that are too numerous to fit into its pouch.[32] In these brooding species, the eggs are relatively large, and supplied with yolk, and they generally develop directly into miniature starfish without an intervening larval stage.[29] The developing young are called lecithotrophic because they obtain their nutrition from the yolk as opposed to "planktotrophic" larvae that feed in the water column. In Parvulastra parvivipara, an intragonadal brooder, the young starfish obtain nutrients by eating other eggs and embryos in the brood pouch.[36] Brooding is especially common in polar and deep-sea species that live in environments unfavourable for larval development[33] and in smaller species that produce just a few eggs.[37][38]

In the tropics, a plentiful supply of phytoplankton is continuously available for starfish larvae to feed on. Spawning takes place at any time of year, each species having its own characteristic breeding season.[39] In temperate regions, the spring and summer brings an increase in food supplies. The first individual of a species to spawn may release a pheromone that serves to attract other starfish to aggregate and to release their gametes synchronously.[40] In other species, a male and female may come together and form a pair.[41][42] This behaviour is called pseudocopulation[43] and the male climbs on top, placing his arms between those of the female. When she releases eggs into the water, he is induced to spawn.[40] Starfish may use environmental signals to coordinate the time of spawning (day length to indicate the correct time of the year,[41] dawn or dusk to indicate the correct time of day), and chemical signals to indicate their readiness to breed. In some species, mature females produce chemicals to attract sperm in the sea water.[44]

Starfish? If I hear that again, I'll be very surprised.

Thank you. That's everything I ever wanted to know about starfish. In fact, that's more than I ever wanted to know.

My starfish.

No trouble, I vetted it.

Asleep.

Me too.

You learn something new every day. I truly don’t get the analogy, either. Makes no sense at all.

Isn't the obvious answer geoduck?

That makes sense. At least as much as 'starfish'.
