🐙 Daily Cephalopod Fact: 🐙

Coconut Octopus: This species has been reported to show bipedal locomotion, or "stilt-walking". This involves rolling two legs to walk while the other six legs are used to mimic the appearance of a floating coconut. They have also been bserved using tools for concealment and defense by gathering available debris to create a shelter. Researchers have filmed this species collecting coconut half-shells from the sea floor, that had been discarded by humans. They were then carried up to 66 ft and arranged around the body of the octopus to form a spherical hiding place similar to a clam-shell.

Наутилус (лат. Nautilus) — род головоногих моллюсков, которых относят к «живым ископаемым». Самый распространенный вид — Nautilus pompilius. Наутилусы относятся к единственному современному роду подкласса наутилоидей. Первые представители наутилоидей появились в кембрии, а его развитие пришлось на палеозой. Наутилиды почти вымерли на границе триаса и юры, но все же дожили до наших дней, в отличие от своих родственников аммонитов. Некоторые виды древних наутилусов достигали размера в 3,5 м. Представители самого крупного вида современных наутилусов достигают максимального размера в 25 см.

Спиральный «домик» моллюска состоит из 38 камер и «построен» по сложному математическому принципу (закон логарифмической прогрессии). Все камеры, кроме последней и самой большой, где размещается тело наутилуса с девятью десятками «ног», соединяются через отверстия между собой сифоном.  Раковина наутилуса двухслойная: верхний (наружный) слой – фарфоровидный – действительно напоминает хрупкий фарфор, а внутренний, с перламутровым блеском – перламутровый. «Домик» наутилуса растет вместе с хозяином, который перемещается по мере роста раковины в камеру попросторней. Пустое жилище моллюска после его гибели можно встретить далеко от его места обитания – после гибели «хозяина» их раковины остаются на плаву и перемещаются по воле волн, ветров и течений.

Интересно, что двигается наутилус «в слепую», задом наперед, не видя и не представляя препятствий, которые могут оказаться на его пути.И еще одно удивительное качество этих древних обитателей Земли – у них потрясающая регенерация: буквально через несколько часов раны на их телах затягиваются, а в случае потери щупальца быстро отрастает новое.

Nautilus is a genus of cephalopods, which are classified as "living fossils". The most common species is Nautilus pompilius. Nautilus belong to the only modern genus of the Nautiloid subclass. The first representatives of the Nautiloids appeared in the Cambrian, and its development took place during the Paleozoic. The Nautilids almost died out on the border of the Triassic and Jurassic, but still survived to the present day, unlike their Ammonite relatives. Some species of ancient Nautilus reached a size of 3.5 m. Representatives of the largest species of modern nautilus reach a maximum size of 25 cm.

The spiral "house" of the mollusk consists of 38 chambers and is "built" according to a complex mathematical principle (the law of logarithmic progression). All chambers, except the last and largest, where the nautilus body with nine dozen "legs" is located, are connected through holes with a siphon. The nautilus shell is two–layered: the upper (outer) layer – porcelain–like - really resembles fragile porcelain, and the inner, with a mother-of-pearl luster - mother-of-pearl. The nautilus's "house" grows with its owner, who moves as the shell grows into a larger chamber. The empty dwelling of a mollusk after its death can be found far from its habitat – after the death of the "owner", their shells remain afloat and move at the will of waves, winds and currents.

Interestingly, the Nautilus moves "blindly", backwards, without seeing or imagining the obstacles that may be in its path.And another amazing quality of these ancient inhabitants of the Earth is that they have amazing regeneration: in just a few hours, the wounds on their bodies heal, and in case of loss of tentacles, a new one grows quickly.

the 5 last remaining black diatom bandanas! unsure if I’ll be able to get another round of these printed so if you have your eye on one now’s a good time to order! more of the light colorway are available as well. If you order this morning they’ll be in the mail this afternoon as I’m heading to the post office today! order here, and I appreciate any reblogs to boost!

VERY IMPORTANT a dam in the Netherlands, the weerdsluis lock, is directly on a migratory path for spawning fish. They have a worker stationed there to open the door for the fish, but they can take a while to open it. So to keep the fish from getting preyed on by birds they installed a doorbell. Only, the fish don't have hands to ring the doorbell. If you go to their website, they have a LIVE CAMERA AND A DOORBELL that YOU RING FOR THE FISH when they're waiting, and then the dam worker opens the door for them! I can't express how obsessed I am with this. look at this shit. oh my god.

Please check on the fish doorbell once in a while :)

🐙 Daily Cephalopod Fact: 🐙

Blanket Octopus: Blanket octopuses are immune to the venomous Portuguese man o' war, whose tentacles the male and immature females rip off and use for offensive and defensive purposes. Like many other octopuses, the blanket octopus uses ink to intimidate potential predators. Also, when threatened, the female unfurls her large net-like membranes that spread out and billow in the water, greatly increasing her apparent size.
