The Life Story Of A Jellyfish
This article is obviously geared towards people who are interested in jellyfish. Perhaps people who are studying them, or are going to see them and want some background information. Maybe a kid who is doing a project for science class. The article tells us how certain types of jellyfish mate, and also how they stay in a swarm. Jellyfish don't have eyes, but they can sense gravity (they know which way is up and which way is down), they can sense light and dark, and they position themselves according to the currents of the water in order to not get separated from one another to avoid predators. Jellyfish predators include: sea turtles, seagulls, and big fish(tuna, ocean sunfish, and swordfish mainly). People are scared of jellyfish because of stinging right? Well, it turns out that jellyfish don't hunt us down to sting us as we might think. they more or less run into us, and according to the article, "since we are too big to eat, they perceive us as attackers." Jellyfish die not long after the mating process. They turn from clear to cloudy, and they drop to the ocean floor. The tone of this article was very informational, yet casual, and it had a little humor in it. The funniest quote in the article was " All the medusa(jellyfish species) has to do is eat and have sex. I don't call that a bad life." There are more than 1,000 different species of jellyfish, and more that we probably don't even know about yet. The author of this article is Constance Casey.
