What are the 4 main stages of the jelly life cycle?

The main phases include the larva, polyp, and medusa.

What is the life cycle of a crystal jellyfish?

The life cycle of free-swimming scyphozoan jellyfish typically consists of three stages. A sessile polyp (scyphistoma) stage asexually buds off young medusae from its upper end, with each such ephyra growing into an adult. The adults are either male or female, but in some species they change their sex as they age.

Do all jellyfish start as polyps?

The difference is that a jellyfish will develop into new stages beyond the polyp, while an animal like an anemone will essentially become an “adult polyp”. Depending on the species, the jelly can remain in this polyp stage for years.

What are jellyfish eggs called?


What is a jellyfish period?

A. If you notice on heavy days of your period that blood seems extra-thick, and can sometimes form a jelly-like glob, these are menstrual clots, a mix of blood and tissue released from your uterus during your period. They can vary in size and color, and usually, they are nothing to worry about.

How long can a jellyfish live?

How long do jellyfish live? Most jellyfish live less than one year, and some some of the smallest may live only a few days. Each species has a natural life cycle in which the jellyfish form is only part of the life cycle (see video clip showing different life cycle stages).

Can jellyfish talk to each other?

Do jellyfish communicate? Jellyfish do not communicate like we do; they do not have a brain or language but some can flash colourful lights. Scientists think these may be used to disguise them or even to attract prey. Jellyfish can signal each other.

How smart is a box jellyfish?

Highly-Advanced Adaptations. Box jellies are highly advanced among jellyfish. They have developed the ability to move rather than just drift, jetting at up to four knots through the water. They also have eyes grouped in clusters of six on the four sides of their bell.

How do jellyfish do anything without a brain?

Instead of a single, centralized brain, jellyfish possess a net of nerves. This “ring” nervous system is where their neurons are concentrated—a processing station for sensory and motor activity. These neurons send chemical signals to their muscles to contract, allowing them to swim.
