Can Jellyfish see you?

Are lobsters immortal?
The lobsters’ longevity may be connected to the behaviour of their DNA. The long chromosomes in animal cells have special tips on their ends, called telomeres, that help protect the DNA. … In other words, American lobster cells apparently don’t age in a normal way, making the lobsters biologically immortal.
Is it safe to swim with jellyfish?
