 Mysterious Cephalopod Species Wandering in the Deep  

     Cephalopods are one of the most interesting and biologically interesting animals there are, ranging from giant squid to octopuses the size of a palm, it was obvious that such a large and varied family would have mysterious members still unclassified and that they have many mysteries on top of it. We begin. with this small compilation of mysterious cephalopods.

 

Magnapinna S.P B

      It is an undescribed species of giant squid, known from a single immature specimen, collected in the waters of the North Atlantic, captured in the coordinates of latitude 42.8°N 29.3°W. 

It is characterized by its dark hepidermal pigmentation that is epithelial, unlike the chromatophore pigmentation found in other species of the genus Magnapinna. 

The only known specimen of Magnapinna sp. B is a juvenile male, 95 millimeters (3.7 in) long, currently undescribed and located in the Bergen museum. 

  

         Grimpoteuthis plena

     It is an archaic species of deep-sea octopus similar to others already known and that is why it is difficult to distinguish. 

It was collected in the northwest Atlantic in 1880, at a depth of 1,963 meters, it was found at a latitude of 37º 35'N and a longitude of 71º 18'W along with other species of the same genus found in the nearby area. The mantle of the specimen reached 57 millimeters long and its total length reached 185 millimeters and with disproportionate tentacles, some of its arms measuring longer than the others. having between 55 and 60 suction cups per arm, the largest of which were 2.5 millimeters in diameter. The octopus's cirri are short. Its fins each measure 32 millimeters long. The eyes are small: each one is 12 millimeters in diameter.

The specimen was too damaged so it was not possible to study it in depth, it is still expected to continue to exist, although due to its current state, the age of the case, its indistinguishable appearance and other factors makes its existence very doubtful. 

              Luteuthis shuishi

     It is a small, bright purple, gelatinous octopus that lives in the South China Sea. 

It is known for a single female specimen captured at 767 meters, this was described as the rest of its genus, having short arms and is quite gelatinous, the total length of the octopus is about 300 millimeters, currently it is known that it possibly still exists, but Due to the depth in which it lives it is difficult to verify. 

Grimpoteuthis hippocrepium

     It is a species of octopus, known from a single specimen collected in 1904, collected off the Colombian coast of the eastern Pacific Ocean. This octopus had 50 suction cups on its arms, as well as a horseshoe shell, a unique feature of its kind, being smaller than the rest of the octopuses in its area, measuring 80 millimeters long, living at a depth of 3,332 meters. 

Due to the age of the case and the fact that it is known from a specimen found in 1904, which was poorly preserved, several characteristics of the species are unknown and it has not been studied in depth and it is believed that it could be a synonym or morph of another.

 

           Grimpoteuthis pacífica

      It was a species of octopus, described by a severely damaged specimen discovered in 1885. 

Originally captured in Papua, New Guinea, specifically in front of the coral sea, at a depth of 4,500 meters below sea level, it was an intense purple color and its fins measured a total of 55 millimeters long, each arm It has 52 suckers, the largest of which measures 2.5 millimeters wide, its arms vary in length from 130 millimeters to 170 millimeters long, and its eyes are very large.  

It is not completely described and it is not easy to separate it from other species of octopus similar to it, and it has not been seen again, although it could still exist, so it is not known if it really exists.
