Are female octopus larger than males?
Similarly, it is asked, do female octopus eat males?
Male octopuses have a big problem: female octopuses. Each male wants to mate and pass on his genes to a new generation. The trouble is, the female is often larger and hungrier than he is, so there is a constant risk that, instead of mating, the female will strangle him and eat him.
Additionally, what is it called when females are larger than males? Sexual Dimorphism. Sexual dimorphism is the systematic difference in form between individuals of different sex in the same species. For example, in some species, including many mammals, the male is larger than the female. In others, such as some spiders, the female is larger than the male.
Also asked, why are female fish larger than males?
In this fish, the males are characterized as being up to 60 times larger than the females. The male's increased size is believed to be advantageous because males collect and defend empty snail shells in each of which a female breeds. Males must be larger and more powerful in order to collect the largest shells.
Are female snakes larger than males?

In many spider species, females eat the males after sex. Studies have suggested various complex evolutionary reasons involving costs and benefits to the species, sperm competition and esoteric sexual selection schemes. Big females eat their puny mates simply because a) they're hungry and b) they can.Why do octopus die after their eggs hatch?
Octopuses are semelparous animals, which means they reproduce once and then they die. After a female octopus lays a clutch of eggs, she quits eating and wastes away; by the time the eggs hatch, she dies.

Unlike females, "males have a modified third right arm called a hectocotylus, which has a sperm groove down it and a specialized tip," Mather said. To mate, a male will insert his hectocotylus into the female's mantle cavity and deposit spermatophores (sperm packets).Are cats sexually dimorphic?
After generations of male-male competition, the males of some species evolve to be much larger than their mates. Most big cats have a form of sexual dimorphism where males are bigger than females, said co-author Julie Meachen-Samuels, a biologist at the National Evolutionary Synthesis Center in Durham, NC.Why are female blue whales larger than males?

Snakes have no visible ear, so they don't hear sounds as we do. But it's not quite right to say that snakes are deaf. They have vestiges of the apparatus for hearing inside their heads, and that setup is attached to their jaw bones, so they feel vibrations very well and may hear low-frequency airborne sounds.How do garter snakes mate?
Garter snakes begin mating as soon as they emerge from brumation. During the mating season, the males mate with several females.
