The common octopus only lives an average of three to five years, though, so it doesn't have much time to waste. Once the octopus reaches adulthood, it will eventually get the urge to mate. As with most creatures, the octopus's main purpose in life is to reproduce. However, if it knew just what was waiting for it soon after, it might think twice. Both the male and female octopuses die soon after mating. The male dies a few months afterward, while female dies shortly after the eggs hatch.
For octopuses, mating is a pretty subdued affair. A few species have flashy mating rituals, but many octopuses seem like they're just conducting business.
The male octopus has a modified arm called the hectocotylus , which is about 3 feet 1 meter long and holds rows of sperm. Depending on the species, he will either approach a receptive female and insert the arm into her oviduct or take off the arm and give it to her to store in her mantle for later.
After mating, the male will live for a couple of months before he dies. Sometimes the female also eats the male to keep her alive because she will stay put to guard her eggs till they hatch. The result from not eating to protect the eggs with numbers up to , allows her to live long enough till the eggs hatch. So at the end of the day, both the males and females die after mating and having the babies.
You might have heard of animals who mate themselves to death before, and Phascogale is an example of male animals that die after mating. Being the largest known mammal to kick the bucket after sex, Phascogale is one poor animal in sex life.
A dominant female will choose a male, and he will spend so much energy trying to impress the female it fries his own immune system. The males die of stress, and sometimes they fall prey to prey and eaten by owls, foxes, and cats. At the end of the day, male Phascogale is bound to die after their first and only breeding season. We all know that the male praying mantis has a very sad love story, a sad mating story specifically.
Normally, the male praying mantis is smaller than the female; and that brings extra opportunity and ease for the female to eat. The first part to bite is the head, either after mating or during fertilization. So cold, right? Some research has shown that the male appears to thrust more vigorously, but they tend to be calmer after they lose the heads.
By eating the male, the newly-widowed she-mantis ensures that her man is still providing for their offspring despite his death. Trans volcanic bunchgrass lizard or bunchgrass lizard is a lizard species endemic to Mexico.
Just like the name suggests, these lizards live in bunchgrass grassland habitats, but what is interesting about them is their mating habits. The male and female are destined to die after successfully mating and giving birth to their young. In captivity, towards the end, sometimes she'll tear off her own skin, and eat the tips of her own tentacles. Now, scientists have figured figured out why this grim scenario happens. It has to do with the optic gland between the octopus's eyes; a gland similar to the pituitary gland in humans.
In , researchers removed this gland and found that the octopus' mothering instincts disappeared. She abandoned her eggs, started feeding again, and went on to live a much longer life. The maturation of the reproductive organs appears to be driven by secretions from the optic gland. These same secretions, it seems, inactivate the digestive and salivary glands, which leads to the octopus starving to death.
The greater blue-ringed octopus, however, is considered to be one of the most venomous animals known; the venom of one is enough to kill ten grown men. It uses the neurotoxin tetrodotoxin, which quickly causes respiratory arrest. Although octopuses usually go after prey smaller than themselves, they can use their strength to overpower substantial adversaries, including sharks.
In fact, it was also in Seattle, at the Seattle Aquarium, that a giant Pacific octopus was filmed killing a shark a few years ago. Researchers have determined that octopuses — the most neurologically complex invertebrates — both feel pain and remember it, responding with sophisticated behaviors and shedding new light on the unsolved mystery of how invertebrate animals experience pain.
Females exercise mate choice, rejecting unwanted and unfit males by cannibalizing them. Mate choice often correlates size with fitness level ; smaller males tend to be less aggressive and display a low level of fitness; smaller males are therefore eaten more often because of their undesirable traits. To identify their sex, male A. Live octopus is a delicacy in some parts of the world, including South Korea and Japan. Octopus feel pain and they feel themselves being chopped up and eaten alive.
The octopus may also adopt deflective markings to scare away potential predators. After a male and female mate, the female squid lays eggs. Often, the male will die a short time after mating , and the female will die once she has released her eggs. Squids, octopuses, and cuttlefishes are among the few animals in the world that can change the color of their skin in the blink of an eye.
