Octopuses do the darndest things. Like kill their mate during mating — by strangling him with three armsaccording to new observations from the wild. Enterprising scientists Christine Huffard and Mike Bartick watched wild octopuses in action.
As it turns out, the female octopus, Raspberry, is already fertilized. Aquarium staff made the discovery this morning. Last year, the aquarium couldn't find a female large enough to match Kong, the pound male that they fished out of Puget Sound.
The charge of wandering hands - or tentacles - is a bit unfair to level at an octopus, given that the mollusc has eight to control. But scientists have discovered that, far from being the loners marine biologists had categorised them as for decades, octopuses are pretty lascivious. The Marine Biology journal has published research by scientists from the University of California, Berkeley, which found Abdopus aculeatus practise sexual habits that amount to "more than just arm-wrestling".
Octopuses are considered the most intelligent of all invertebrates. Worldwide there are around recognized octopus species. The amazing facts about octopus are vast. But did you know that octopus has a dangerous sex life?
For the first time, they have witnessed two deep-sea octopuses having sex — only to discover they have been watching the intimate embraces of two males of different species. Last December, the deep-sea submersible Alvin ventured metres below sea level to the East Pacific Rise, where it encountered the two octopuses and filmed 16 minutes of torrid footage. Voight, an octopus expert, was called in to study the video recording.
Often considered the smartest invertebrates animals without backbones on the planet, octopuses can use tools, unscrew jar lids and tightly control their body color to match their surroundings. Octopuses come in all shapes and sizes and inhabit diverse regions of the ocean. There are about different species of octopuses in the genus Octopusand at least another species in other genera, said Jennifer Mather, a cephalopod expert at the University of Lethbridge in Canada.
In the s, a biologist named Arcadio Rodaniche was working at the Smithsonian Tropical Research Institute in Panama when he became familiar with a curious type of octopus. That's because the original attempt to describe the species was rejected, and until now, never attempted again. In fact, hardly anyone in the scientific community had ever seen one.
All rights reserved. A female blanket octopus is dramatically larger than males, which put their energy into finding females in the open ocean. It's true that gorilla males are much bigger than females. But dramatically large females are the norm in some species of frogs, turtles, lizards, snakes, and spiders.
The mystery of octopus sex is one of life's greatest questions. We know that octopus reproduction must happen, since octopuses not octopi! If you've never thought about this before, you're thinking about it now.
White bodies WBmultilobulated soft tissue that wraps the optic tracts and optic lobes, have been considered the hematopoietic organ of the cephalopods. Its glandular appearance and its lobular morphology suggest that different parts of the WB may perform different functions, but a detailed functional analysis of the octopus WB is lacking. The aim of this study is to describe the transcriptomic profile of WB to better understand its functions, with emphasis on the difference between sexes during reproductive events.
