In male seven-arm octopuses (Haliphron atlanticus), the hectocotylus develops in an inconspicuous sac in front of the right eye that gives the male the appearance of having only seven arms. In argonauts , the male transfers the spermatophores to the female by putting its hectocotylus into a cavity in the mantle of the female, called the pallial ...
Many octopus arm anomalies have been recorded, [13] [14] including a 6-armed octopus (nicknamed Henry the Hexapus), a 7-armed octopus, [15] a 10-armed Octopus briareus, [16] one with a forked arm tip, [17] octopuses with double or bilateral hectocotylization, [18] [19] and specimens with up to 96 arm branches.
The common blanket octopus (Tremoctopus violaceus) exhibits one of the most extreme sexual size-dimorphism known in any animal near its size or larger. [3] [4] Females may reach 2 m (6.6 ft) in length, whereas the males are 2.4 cm (1 inch). The weight ratio is at least 10,000:1, and can probably reach as much as 40,000:1.
This would explain pupils shaped like the letter "U", the letter "W", or a dumbbell, as well as the need for colourful mating displays. [62] Attached to the brain are two organs called statocysts (sac-like structures containing a mineralised mass and sensitive hairs), that allow the octopus to sense the orientation of its body. They provide ...
The seven-arm octopus is so named because in males, the hectocotylus (a specially modified arm used in egg fertilization) is coiled in a sac beneath the right eye. Due to this species' thick, gelatinous tissue, the arm is easily overlooked, giving the appearance of just seven arms. However, like other octopuses, it actually has eight. [5]
The Abdopus capricornicus is known for having mottled skin with their most distinguishable features being white rings going down their arms and small ringed white spots scattered around their body. This octopus also has white spots along the dorsal mantle of its body. These white spots are characteristic as their shape is crescent-like. [7] "
To achieve a sculpted look with the upper body, you need a well-rounded routine made up of exercises that target every part of the arm, including the shoulders, triceps and biceps.. Strong arms ...
When the octopus becomes aroused, the radial muscles contract which expands the chromatophores. In contrast, when the octopus is in a relaxed state, the chromatophores will retract into the elastic sac. [6] As these chromatophores interact with their environment, it enables the octopus to select, at any time, a particular body pattern.
