Bigfin Squid- Rare vivid Morphological cephalopods

Facts of the deep water stranger

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

A video was captured by the ROV Tiburon 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 dark, cold water. You could barely see how it eats which is why nobody is certain on the kind of food they eat but left researchers with the assumption that it’s 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 exactly what they should do.

Some believe adult creatures have also been seen. The arms and tentacles of a bigfin squid are damn long. Research says a bigfin squid is 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 are found in the deep ocean water of the Atlantic and Pacific oceans. As they imply “Bigfin, “they truly have large fins that outstretch outward from their body segment. They also have ten arms, which are of equal segment and thickness. While other squid species have eight short arms and two long tentacles. In most cases, the arms of bigfin squids are hung at the right angle, just as if they’ve elbows. 

About ten years ago, in the middle of the Gulf of Mexico, A ROV from the shell oil company was spotted 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 depths of the ocean, 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 tentacles of the bigfin squid have been 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 gotten the chance to examine the bigfin squid. The little we know is based on the assumption that they’re from the genus 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 are hung in a weird position, even outstretching at sharp angles to the body axis, then suddenly turn afore, therefore giving the appearance of 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 been totaled to be 15 to 20 times the mantle length when stretched.

What does a bigfin squid eat?                                            

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

There are about 5 Magnapinna species. They have a similar appearance, and they are 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 are used more for catching prey.
