Bigfin Squid- Rare vivid Morphological cephalopods

Facts of the deepwater stranger

Bigfin squid can describe as rarely seen cephalopods with a distinctive morphological structure. They classed in the genus Magnapinna and the family of Magnapinnidae. It happens to be among animals known only from larval, paralarvae, and juvenile specimens. Without any representative for the sample, there is no way to confirm if they belong to the same genus. The first specimen of the Magnapinna has discovered in the Southern Caribbean ocean.

According to the morphology, researches identified them as a member of genus Magnapinna. This genus has poorly identified yet since its members are deep-sea dwellers—eleven specimens of deep-sea creatures of this genus deposited in worldwide labs. Magnapinna members of species are characterized by unique brachial morphology among all identified cephalopods. Scientists have identified only 49 species of cephalopods in shallow waters of the Colombian Caribbean region.

The ROV (remotely operated vehicle)Tiburon captured a video in 2001 of the Bigfin Squid. The video shows a bigfin squid contemplating how it could best slip its tentacles into an ear and brain.

Most details of this creature remain concealed in the dark, deep, cold water. You could barely see how it eats, so nobody identified what kind of food they eat. But some researchers with the assumption believe that with its extra length limbs along the ocean floor, picking any edible organisms and eating them or they stay motionless and gently capture its prey as it passes by. Unfortunately, researchers have not done much digging on the organism, but I guessed they did precisely what they should do.

Some believe adult creatures have also identified. The arms and tentacles of a Bigfin squid are very long. Research says a Bigfin squid is about 13 to 26 feet (4 – 8m) long. A video about this strange was also released by Shell Oil Company on November 11, 2007, in Mexico.

Bigfin squids can found in the deep ocean water of the Atlantic and Pacific oceans. As they imply “Bigfin, “they genuinely have large fins that outstretch outward from their body segment. They also have ten arms, which are of equal component and thickness. While other squid species have eight short arms and two long tentacles. In most cases, bigfin squids’ arms are hung at the right angle, just as if they’ve elbows. 

Rare capturing in the Gulf of Mexico

About ten years ago, in the middle of the Gulf of Mexico, A ROV from the shell oil company spotted a live specimen in the dark waters of Alaminos Canyon. It was roughly 8,000 feet below the ocean floor, dawdling along when an operator came upon the bigfin Squid that restrains both the ocean’s depths, which was existing in mind but not immediately available to consciousness. It was a long- arm squid, 26″ foot long with elbowed tentacles and pulsating fins.

There aren’t many details about the Bigfin squid. Research says the Bigfin squid tentacles have twisted and broken; it is therefore impossible to measure their length. The reason for that is because no Bigfin squid have been caught except a brief glimpse of the dark and coarse video released by Shell Oil Company in Mexico. 

There is sincerely not much to tell about the Bigfin squid. Most scientists have never taken the chance to examine the Bigfin squid. The little we know has based on the assumption that they’re from the Magnapinna and an adult form of the Magnapinna squids.

The forms and structure of a Bigfin squid 

Bigfin squid has visible large, elastic arms and tentacles of about equal sizes, which gives them the nickname “long-arm squid”. These appendages hung in a weird position, even outstretched at sharp angles to the body axis, then suddenly turn afore, therefore giving strange elbows. These strange elbows are about two-third of the length of the mantle (body segment) away from the body axis. The tentacles have estimated to be 15 to 20 times the mantle length when stretched.

What does a Bigfin squid eat?                                   

Nobody knows that the authentic food of this strange animal eats. Nevertheless, some assume that they feed by dragging their arms and tentacles along the ocean floor, therefore grabbing any esculent organism they stumble upon. Instead, they can wait for prey to fall into their arms.

There are about five Magnapinna species. They have a similar appearance, and they just depicted from juvenile specimens. The Bigfin Squid has more distinguishing physiological characteristics, just like other squid species. Other squid species have arms and tentacles that are of different length and physical structure. For instance, the placement of suckers varies, and the considerably longer tentacles use more for catching prey.
