Jellyfish

 

Have you ever wondered what mysteries lay beneath the ocean’s surface? One amazing animal of the ocean is the wondrous jellyfish.

These squishy predators are clear with a colorful appearance. They are brightly colored, somewhat because of the bioluminescence in their body. This is when their photophores contain luciferin and enzyme luciferin which are both capable of emitting flashes of light. These deadly creatures are blue, purple, pink, green, and red. They have no face, but they have a mouth. As astounding as it seems, jellyfish have no brain! They act almost fully on their nervous system.

These mysteries of the deep can range from different sizes, length, and even weight. The Lion’s Mane jellyfish’s length is averaged at 200 feet long, but some can be 300 feet long! The Hydrozoa class can be, at its least, 0.32 centimeters in diameter. The outstanding Nomura jellyfish is overpopulated near Japan because of the tremendous amount of plankton in the South China Sea. The most interesting thing about it is that it can weigh up to four-hundred fifty pounds! Imagine being crushed underneath this humongous jellyfish with deadly stings that people call Godzilla! Jellyfish are basically see-through and usually have long tentacles dotted with stinging cells that can be fatal to you.

The habitat for these eye-widening "beasts" is salt water. However, some jellyfish live in freshwater lakes. Where they live is mostly cold, as not much light penetrates under the surface of the ocean. In the ocean there is water with fish, plankton, and other animals in there. Jellyfish live in the ocean because the plankton and fish they eat live in there. One of their main predators is the ocean, because it washes them onto the shore.

These eerie invertebrates behave, or act, quite strangely. They have very deadly stings that could kill you in minutes! For hunting, these see-through organisms use their tentacles to grab and paralyze prey and put them in their mouths. Jellyfish are hard to see because of rare light and their clearness.

They have a useful birth system where sperm from the male fertilizes the egg from the female. This makes a polyp. The polyp creates more of itself like a stack of saucers. These are called colonies. Each "saucer" detaches itself from the first polyp and the cycle repeats again and again.

So you can see, jellyfish are amazing creatures with clear appearances, different habitats, helpful reproduction, and strange behaviors.
