Desert Solitaire is a collection of treatises and autobiographical excerpts describing Abbey's experiences as a park ranger and wilderness enthusiast in 1956 and 1957. The opening chapters, First Morning and Solitaire, focus on the author's experiences arriving at and creating a life within Arches National Monument. In this early period the ...
The eggs of Pinnoctopus cordifomis are of intermediate size (6.43 ± 0.21 mm L; 1.45 ± 0.11 mm W; 6.41 ± 0.52 mg TW) the yolk can be seen through the wall of the egg and represents approximately 57% of the eggs size, they are pear-shaped. Once the eggs are hatched paralarvae are released which survive without intervention for the duration of ...
This also makes it the longest-living octopus – most octopuses only live for 1 or 2 years – which this octopus beats with its brooding period alone. [ 4 ] [ 5 ] Female Graneledone boreopacifica tend to brood their eggs between the depths of 1,200 and 2,000 metres (3,900 and 6,600 ft); the eggs were never unattended.
Marine scientists discovered what they dubbed an 'octopus garden' nearly two miles below sea level. 'We were just absolutely floored.' Just off California, octopuses are converging by the thousands.
Estimations of egg hatching time (using water temperature and egg size) for O. californiana are up to 1.4 years at 4°C. [11] [12] Mating has never been observed in O. californiana; the males lack the hectocotylus of typical octopus, instead having a series of enlarged suckers that presumably have a role in mating or competition.

Researchers believe the shorter brooding period near warm hydrothermal springs increases a hatchling octopus’ odds for survival. Mystery of octopus garden in ocean’s midnight zone solved by ...
Researchers have documented an active octopus nursery, where hundreds of the deep-sea creatures cluster together to brood their eggs. Rare octopus discovery made 2 miles below the ocean surface ...
The supply of octopus has been constrained by overfishing in many key fisheries [3] and proponents of farming suggest human-induced culturing could help restock natural populations. [4] Opponents of the nascent industry argue that cephalopod intelligence and emotional capacity, as well as the solitary and carnivorous character of octopuses ...
