The Purple-Striped Jellyfish (Chrysaora colorata) is a soft-bodied invertebrate marine (saltwater) animal. An invertebrate is an animal with no bones. It is also known as the Purple-Striped Sea Nettle.
The Purple-Striped Jellyfish has a translucent (see-through) bell-shaped or umbrella-shaped dome body with purple stripes. It has long tentacles (limbs) with eight long dark purple arms and four ‘frilly’ arms. It has no brain, no heart, no blood, no bones, no excretory system, and no gills or lungs. It has nerve receptors in its body that enables it to detect smell, light, pressure, and touch. It is about 98% water.
It grows to about 70 centimetres (28 inches) in length, and 20 centimetres (8 inches) wide.
The Purple-Striped Jellyfish is native to the waters off the western coast of America in Monterey Bay. It prefers warm waters with currents (not still waters).
It pulsates through the water and drifts with the ocean currents and tides.
It feeds on fish eggs and marine organisms, such as zooplankton. The stingers on its tentacles paralyze its prey. It uses an arm to bring the food to its mouth.
It has lots of predators, such as birds, fish, and turtles.
Both males and females release eggs and sperm. Therefore, each jellyfish can produce young without mating with the opposite sex. It is hermaphroditic.
The Purple-Striped Jellyfish begins its life cycle as planula larvae, then as sedentary polyps, and finally as medusa (the adult reproductive phase).
It lives for about 12 months.
