Re: Thread of Creatures of amazing colours and imaginations
Blanket octopus (Tremoctopus sp.) found in tropical and subtropical oceans, the female can reach up to two meters, while the male has only around 2,5 centimeters in size, and she is the only one who has a membrane that resembles a veil, which opens to look bigger and scare away predators (such physical differences between female and male are known as sexual dimorphism). These animals are immune to the toxins of the Portuguese man o' war (Physalia physalis), and use their stinging tentacles as a defense. The male has a special tentacle where it is stored sperm (called hectocotylus), and during mating this tentacle approaches female's mantle, fertilizing thousands of eggs, the male dies soon after this, and the female will carry the eggs until they hatch.
Imagine if your spouse was 40,000 times heavier and a hundred times larger than you. This is reality for the male blanket octopus, which was recently spotted alive for the first time off Australia's northern coast.
