What are some words describing jellyfish that begin with the letter O?

Answer 1

* Oval (at least some of them)

* Ocelli - light sensitive organs that sense light and dark but don't actually detect shapes. Some jellyfish have these.

* Olindiidae - a family of jellyfish in the order Limnomedusae

* Oxygenated - Rather than having lungs, their skin is thin enough to allow their body to absorb oxygen from the surrounding water

* Oral arms - surrounding their mouth

* Organs - they don't have all the organs we normally think of like hearts and lungs, but they do have SOME organs - like sensory organs for example (such as the aforementioned ocelli)

* Organism - like any living thing, it can be classified as an "organism"

* Old - there is evidence of jellyfish in the fossil record going back at least 500 million and possibly more than 700 million years.

* Oceanic - they live in the oceans

* OUCH!, OWWWIE! - when you get stung by one

* Overrunning - they are overrunning a lot of sea areas. Scientists are not certain of all the reasons but it seems to be largely due to another "o" word: OVERFISHING. When an area of the ocean is stripped of all (or nearly) all of the natural predators that eat the jellyfish, the jellyfish proliferate prodigiously. Jellyfish reproduce rapidly and have fast growth rates; they predate many species, while few species predate them; and they feed via touch rather than visually, so they can feed effectively at night and in turbid waters.It may become difficult for fish stocks to reestablish themselves in marine ecosystems once they have become dominated by jellyfish, because jellyfish feed on plankton, which includes fish eggs and larvae.
