Bathypolypus arcticus, the North Atlantic octopus, deep sea octopus or spoonarm octopus is a small species of demersal octopus of the North Atlantic. It is usually found at depths of 200 to 600 m (660–1,970 ft) where the temperature is between 2 and 6 °C (36–43 °F).

Habitat. O. joubini are found in the warm temperate to tropical waters of the Atlantic, thriving in temperatures ranging from 18 to 25 degrees Celsius. They are benthic and are typically found on soft, muddy substrates around 10 to 15 m deep.

Octopuses are found in every ocean of the world and along every coast of the United States. Octopuses live in coastal marine waters and spend much of their time in dens—small holes and crevices in rocks and coral.

There are many different animals that live in the Atlantic Ocean, including manatees, sea lions, humpback whales, Atlantic ghost crabs, starfish, catfish, green sea turtles, gray Atlantic seals, penguins, shrimp, redfish, flounders, sea trout and tarpon.

“Daddy-Longlegs are one of the most poisonous spiders, but their fangs are too short to bite humans”

Females—even virgin ones—make the ultimate sacrifice for their colony’s young, a new study says. WATCH: Females of this spider species give their own bodies to their offspring to eat. “When she is almost depleted, the offspring will crawl onto her and start eating her.” …

For male widow spiders, mating is an infamously dangerous activity. In these species, which include the black widow and redback, the large females will often devour the smaller males during sex—hence the “widow” in their names. So, by committing “copulatory suicide,” the males guarantee their future fatherhood.

This behavior may be triggered by aggression, where females carry over hostility from their juvenile state and consume males just as they would prey. Sih and Johnson surmise that non-reproductive cannibalism can occur due to a remnant of an aggression trait in juvenile females.

They do it in the first place because their neurons are wired that way. They don’t care that they get eaten, they are just following their instinctive behaviors. Their neurons are wired that way because the ones whose neurons WEREN’T wired that way did not mate, did not pass along their genes, and did not reproduce.

Sure, love can break your heart. But if you’re a male praying mantis, it can literally eat you alive. During mating, the female bites off his head… and then devours his corpse for nourishment.

The praying mantis, black widow spider, and jumping spider are among a number of species that devour their mates. Sexual cannibalism is also found in other invertebrates, including a relative of the praying mantis, the Chinese mantis, and scorpions.

Sexual cannibalism is common amongst praying mantises. Typically, the female is the aggressor, which encourages males to approach the female carefully and cautiously when mating. They wrestle and sometimes seriously injure the females in an attempt to mate and avoid being eaten.

The female mantis after mating starts swelling and then her abdomen is going to become extremely fat. Also, she will stop flying and eat much. The stored sperm fertilizes the eggs, since the latter pass through the reproductive system of the female. The female mantises die around two weeks after they lay their eggs.
