The marine world is replete with a great diversity of living things, and recently scientists have discovered a new type of marine organism, which lives near the ocean floor.
Using high-resolution imaging devices known as “depth explorers” connected to actuators that can be managed remotely, scientists were able to dive off the coast of Puerto Rico, USA, and identify a strange type of organism, which belongs to the division of “ctenophores,” which was called The name is Duobrachium sparks are.
Several known metatarsals are given by several common names such as “comb jellies”; This is relative to its fine, comb-like fringes. Some also have other names such as “sea apricot” or “sea gooseberries” and “Venus’s girdles.”
And although outwardly these creatures resemble a jellyfish; Except that it differs from him. The carnivores are slow-predatory carnivores that feed on small arthropods and other diverse larvae.
So far, 200 species of fish have been identified. A new species is added to this list on average every year as scientists rely on their discovery on video footage, which can be filmed on the ocean floor, due to the difficulty of collecting these samples.
A unique type of catapult
This new type of comb gel was first discovered in 2015. That discovery was also based on video footage without collecting any actual samples that can be accurately studied and their formal characteristics.
However, this is no longer the case. As the depths explorer cameras were this time specially equipped to complete this task, these cameras were able to capture the fine details – some of which were less than a millimeter in length – that make up the discovered comb gel structure.
According to the US National Oceanic and Atmospheric Administration-NOAA press release, the study was published in the journal Plankton and Benthos Research on November 18 this year.
“The discovered comb gel is unique … as we were able to identify and describe it based on the high-resolution videos captured,” said Alan Collins, a marine biologist, and lead team leader.
The cameras were able to capture a group of pictures of three different individuals from the comb gel, found at a depth of 3,900 meters below the sea level. Its swollen, balloon-like body was the most distinctive feature of this species. The long tentacles were another distinguishing feature of this species, which scientists believe act as tentacles to stabilize jelly on the seafloor.
Constant contact with the seafloor
Commenting on these long tentacles, the oceanographer participating in the study, Mike Ford, said, “These organisms move like hot air balloons connected to the seafloor through these two tentacles, which keep the jelly at a certain height from the seafloor.”
He added, “We are not yet sure about the extent of these tentacles contact with the seafloor; however, we noticed a direct connection between them and the seafloor during diving as if these organisms are trying to touch the seafloor.”
Although the long tentacles of two of the samples that were collected did not touch the seafloor; However, all three specimens were only two meters from the bottom, so the presence of these creatures at these deep depths on the ocean floor, where their natural habitats are located, made them hidden from our eyes for all this time.
“We are still in the process of studying the characteristics of these new species, and we are not yet sure of the role these organisms play in the ecosystem, but we believe that they have a role similar to other plankton that is found near the ocean floor,” Ford added.
Ford concludes by saying that they could “see the three species near each other, which means that these creatures are not rare.” Of course, this will give scientists more opportunity to study these organisms in detail and learn about their ecological roles in the future.
