The Survivor

            When a jellyfish is seen in the ocean, most fish would flee instead of charging forward. Looking at their stingers, most people would too. However, this one unique bearded goby actually makes jellyfish a third of its diet. It is immune to a jellyfish's painful stingers, making it possible to be in contact with them. Scientists wonder how this is even possible, since it is the first fish discovered to thrive in an environment filled with jellyfish. All other goby fishes back then were overfished, causing a decrease in the population. This allowed an increase in jellyfish population due to the increase of space in that environment. Eventually, this one special fish became the only survivor. With some experimenting, scientists discovered how the goby was able to thrive in such an environment. This bearded goby spends hours in oxygen-deprived  "mud mats
 on the seafloor , which has poisonous hydrogen sulfide gas. Becoming used to this toxic substance has also given it the advantage with jellyfishes. This goby fish adapted to a toxic habitat filled with blobs of stinging doom. 

            This article relates to biology concepts because it talks about how the only discovered bearded goby fish survived in a jellyfish filled environment through adaptation. Adapting to new environments or environmental factors have helped many species, not only aquatic ones, have a higher rate of survival. It shows that other species living in predator-filled environments might be able to adapt and survive too.

             This was an important article for people to read and think about because it lets us know how there are possibilities for species that are low on population in one area to be able to reproduce and raise the population back. It also lets scientists understand more on how some species can adapt to certain situations in specific environments, which could help them understand some of their behaviors. This information could one day be used to help species that are in dangerously low population rates.
