Purple-striped jellyfish (Imani P.)

  • common name:purple-striped jellyfish, Mauve stinger.
scientific name: Chrysaona Colorata
Scyphozoa:All Scyphozoa's body parts come from a central area. The  ten tentacles of a jellyfish usually incircle the mouth, and gives the orgnisima symmetrical appearance.The Scyphozoans rary in size they can be the small as twelve milimeters in diamater, or can grow to more than two meter these Jellyfis are invertebrates, no brain, no head, no skeleton, or any organs, used for respiration and excretion. The tentacles, is the most famouse. Of the Jellyfish, are covered with nematocysts, the stinging organs.also four large oral arms, 16 stomach pouches and 16 lappets.The average size of the jellyfish is 6.5 cm diameter across the bell.But they may grow 10cm or more. There are approximately 200 species that belong to the Scyphozoa class. The difference between Scyphozoa  jellyfish and the rest of the jellyfish species ,is that the Scyphozoansis one single organism with two layers. The outer epidermis, and the inner gastfrodermis.
Genus: Chrysaora
habitat:Purple-striped jellyfish has a wide distributation in all warm and temerate open water, and is found in the Bermuda, Mediterranean sea, the Adriatic Sea, off the Coast of California and the Atlantic Ocean. This Jellyfish is exclusively marine, inhabiting mostly coastal waters.
Range: Limited range off the coast
 Feeding adaptation:Purple-striped jellyfish is always hunting for food. When pray touches a marginal tentacle of the jellyfish, nematocysts (stingers) are immediately discharged to paralyze prey and then the tentacles bend inward to the nearest oral arm.The arm is used to transport prey to the gastric cavity.
Food:mainly zoo plankton, cope pods, larval, fish, salps, fish eggs, and other jellies.

Defense adaptation:the purple-striped jellyfish has several predators. Many fish species which feed on. As defense against predators this jelly tentacles have stinging nematocysts which inject toxins into any animal contact.These jelly are eating by sunfish, and blue rockfish.

Movement adaptation:the purple-striped jellyfish's bells pulses to move short distance, to father the purple-striped jellyfish rides the current. these jellyfish are continuously in motion, at least during the day.

social behavior: no social behavior

Reproductive behavior:purple-striped jellyfish reproduces sexually to form planula larvae, they reproduce year round. living in aggregation make it easy for the jellies to locate sexual partners these jelly has no sessile polyp stage instead the planula larva develops directly into ephyra stage , which grows to become a purple-striped jellyfish.

 Interesting facts:1-the purple-striped jellyfish life cycle was first discovered in Monterrey Bay Aquarium in California .
2-Since drivers have seen ocean sunfish eating these jellies, we know some fishes must be immune to the sting.
3-Purple-striped jelly are bioluminescent (able o produce light) the light is green or purplish color.
