Their main body is normally around 8 centimetres (3”) tall and, including the arms, approximately 15 centimetres (6”) long. Coconut octopuses are commonly found throughout the tropical Pacific and the Indian Ocean. The octopus will carry a shell with it while searching for another, testing several as it scavenges as a hermit crab might. Walk the walkĬoconut octopus ( Amphioctopus marginatus) is even capable of bipedal (2-legged) movement and slit-walking, which allows them to carry the coconut or clamshells, with the remaining 6 arms. Often the shells and husks that the coconut octopus gathers, will be used for dens or “defensive fortresses”. Although they have the ability to burrow and hide in the sand, they prefer the extra security these tools are giving them. Named for their use of coconuts as tools for defence, the coconut octopus can also use clamshells, or these days a variety of plastic rubbish, depending on their size. True royalty! The octopus and its coconut As an added bonus, the haemocyanin makes the octopus’s blood look blueish. But, with 3 hearts, the octopus isn’t really worried about high blood pressure. Although in cold conditions and with low oxygen levels, haemocyanin transports oxygen more efficiently than haemoglobin, it also tends to make the blood thicker, resulting in blood pressures that can exceed 75 mmHg (10 kPa). Octopuses have 3 hearts and depend on the copper-rich protein, haemocyanin, for oxygen transport throughout the body. Amphioctopus marginatus has 3 hearts for life This allows the octopus to evolve/adapt/learn from the experiences of previous generations, without actually being taught. More than 60% of RNA transcripts for their brains are re-coded by editing, compared to less than 1% for that of a human. Octopuses, as well as some other cephalopods, are capable of greater RNA editing (which involves changes to the nucleic acid sequence of the primary transcript of RNA molecules) than any other organism. The parrot-like beak of all octopus species contains venomous saliva and is the only hard part of their bodies. Octopuses are basically “brains with arms”, or “thinking muscles”, that can control their bodies to such an extent, that they’ll fit through any opening the size of their beak. Each arm has a multitude of muscle-controlled suction cups, that can grab, feel, manipulate, and even taste objects. This basically means that they can extend/contract their arms, twist left or right, bend at any place in any direction and/or be held rigid. Lacking skeletal support, this creature’s arms work as muscular hydrostats and contain longitudinal, transverse and circular muscles around a central axial nerve. They have a large brain that extends into the nervous system of their arms! This means that its brain is not in 1 particular place, as with most other creatures, but has more of a “Multiverse” approach to brain function.
