Jellyfish Game Quiz Online

This page features a Jellyfish Game Quiz Online. It is an exercise for students studying science in 3rd, 4th, 5th, 6th to 8th grades.These organisms are inique in several ways. One is their bell shape and another is the way they move from place to place. They also have tentacles with sharp spikes which they use to catch their prey and defend themselves. In this game students will answer fifteen questions about jellyfish. This game is suitable for classrooms. Feel free to share the game in your groups.

 

Jellyfish Facts

Among other names, jellyfish are also known as sea jellies and medusa. Both names refer to the medusa-phase. These creatures belong to the phylum Cnidaria and the subphylum Medusozoa. You can learn more about these creatures by reading this article. You will also learn about their habitat and how they protect themselves. But before we get started, let's first review what these creatures are.

jellyfish types

While most species of jellyfish are short-lived, there are several that can live for years. The only truly immortal jellyfish is the Turritopsis dohrnii, which reverts to a polyp stage after reaching adulthood. It is the only known transdifferentiating animal. Besides their life-cycles, jellyfish also have very similar characteristics. For instance, most species of jellyfish reproduce in a sexual manner, releasing eggs and sperm into the water. Once mature, most jellyfish release their eggs and sperm into the water, though some may fertilize their eggs inside their mouths.

In the scientific world, jellyfish belong to the class Scyphozoa, a subphylum of the class Medusozoa. Its name comes from the Ancient Greek word medousa, meaning "rule over." There are thousands of different species of jellyfish, but they represent only a small fraction of the aquatic life. Some species are a hundred feet long, while others can reach fifty feet in length.

jellyfish life cycle

 

 

While many people don't know it, jellyfish have very complicated lives, so much so that they have the potential to live thousands of years. A few jellyfish species are even considered pets. These include the Moon Jellyfish and the Blue Blubber Jellyfish. While the latter live for only a few years, cannonball jellyfish can live for thousands of years. Before these animals become full-fledged adults, they exist as polyps attached to rocks or corals on the ocean floor. They feed by sucking plankton from the sea floor.

A jellyfish's life cycle is divided into three stages. The first stage, called the sessile polyp, is a bud-off of a young medusa. The next stage is the ephyra, which develops into the adult, which can either be a male or female. The adult jellyfish will brood an embryo within its gut. The second stage is called the medusa, and the jellyfish changes into two different body forms. The polyp stage reproduces asexually through budding. The medusa stage, on the other hand, reproduces sexually through spawning eggs and sperm.

jellyfish habitat

The Jellyfish habitat is one of the most important factors that determine their health and survival. Jellyfish are found in water bodies that range in temperature, salinity, and pH. In addition, the warming climate is causing increasing numbers of these creatures in many locations. To find out what conditions may be hospitable for your local jellyfish population, you can use the NOAA sea-nettle forecasting page.

In the ocean, the Jellyfish habitat is influenced by physical factors, such as the tidal state, wind speed, and the time of day. Chironex fleckeri makes its habitat in the ocean's offshore waters, and the Carybdea branchi lives in coastal waters in the Philippines. Both types of jellyfish live between three and six months. The South African box jellyfish lives in the waters around Port Elizabeth, South Africa.

how jellyfish protect themselves

If you have ever wondered how jellyfish protect themselves, this information will help you understand their amazing mechanism. The tentacles of jellyfish are lined with stinging cells that release a toxic substance into their prey, rendering them unconscious. They also use these tentacles to push prey toward their mouth. Their powerful stings have also led them to develop symbiotic relationships with other fish, so they can feed off one another without getting stung.

In addition to the stinging tentacles, jellyfish also have transparent bodies. These qualities make them a desirable food for many animals, including loggerhead turtles, spadefish, and other creatures. Jellyfish also live on other jellyfish, and hence their larvae will hide inside their tentacles to avoid predators. Their stings are not purposely used to attack humans, but rather serve as a defensive mechanism.

what do jellyfish eat

When food is plentiful, jellyfish will quickly grow. Because they do not have sophisticated anatomy, jellyfish eat anything they can catch. While pet jellies feed on brine shrimp, the larger types of jellyfish will eat fish, plankton, and other organisms. They will also occasionally eat other jellyfish. To determine if your jellyfish consumes prey, try to observe one of these animals in its natural habitat.

Jellyfish are highly versatile. They feed on small fish, animals, and even dead animals.
