What does the Styx jellyfish look like?

The appearance of the Styx jellyfish is a bit like the dementors in the sci-fi movie "Harry Potter". It is dark red, without the sticky spiny tentacles of other jellyfish species, but it has five sheet-shaped tentacles that can extend 6 meters. It was first discovered in Antarctic waters in 1901 and has been seen many times in Antarctic waters for more than 100 years. Let's take a look at what the Styx jellyfish looks like.

What does the Styx jellyfish look like?

The Styx jellyfish is a large jellyfish living in the deep sea. At present, the largest known individual is about 1.4 meters in diameter and 11 meters in length (including tentacles). There are no tentacles on the edge of the umbrella, but there are four well-developed mouths around the mouth. There are many folds on the edge of the umbrella, and the longitudinal muscles under the umbrella are well developed, mainly living in the deep sea of about 2000 meters, and what is interesting is that a kind of deep-sea fish often lives with this kind of jellyfish, which is the only known species of symbiotic fish with jellyfish.

Where are the jellyfish in the Styx River?

There is a lack of research on the living habits of the Styx jellyfish, which was first discovered in the Antarctic waters in 1901. For more than a hundred years, this jellyfish has appeared in the Antarctic waters many times, but its scope of activity is not limited to the South Pole. The jellyfish has been found as far away as Japan, which suggests that the jellyfish is widely distributed. But the jellyfish has been found only 114 times in the ocean since it was discovered more than 100 years ago, the most recent in 2009.

Expansion: what kinds of jellyfish are there?

1. Cubic jellyfish: the whole umbrella part of the cubic jellyfish is cubic, distributed in tropical and subtropical shallow seas, and a few live in the open sea. The stinging cells on the tentacles are highly toxic. Common representative species such as hand-towed jellyfish, box jellyfish and so on.

2. Crown jellyfish: the jellyfish of crown jellyfish are dome-shaped, conical, or flat and parallel, but there is a tight groove in the middle of the outer umbrella, which divides the umbrella into upper and lower parts, and the corresponding gastric sac is also divided into upper and lower parts, mainly deep marine products, such as marginal leaf jellyfish.

3. Cross jellyfish: a bowl jellyfish living in a cross jellyfish camp, consisting of a combination of polyp and jellyfish, often distributed in colder sea water and attached to seaweed, such as trumpet jellyfish and tall cup jellyfish.

4. Flag mouth jellyfish: the umbrella of the flag mouth jellyfish is bowl-shaped and butterfly-shaped, with 8 to many missing edges, with tentacle sacs in the missing, and most of them live along the coast. the common species are sea and moon jellyfish, swimming jellyfish, summer jellyfish and so on.

5. Root mouth jellyfish: the root mouth jellyfish is close to the flag mouth jellyfish, the mouth is not in the middle of the body, but on the movable tentacles, and there is a small opening to accept small food molecules in the water, representing species such as jellyfish, nitrate jellyfish and so on.
