Fun Blue Button Jellyfish Facts For Kids
Gallery
The blue button jellyfish (Porpita porpita) is an organism found floating and moving in the coastal waters of the Atlantic Ocean.
The blue button jellyfish are small organisms known as polyps and are found in water bodies like seas. They depend on crustaceans and copepods for food and are generally hunted by sea slugs and sea snails. They are very small in size and are typically seen in yellow, blue, and turquoise colors.
This organism with polyps has only one mouth, which is situated beneath the float. These organisms have a hydroid colony that looks like tentacles when they extend completely.
The status of these organisms with polyps is currently Not Evaluated. They are not completely dangerous, but their sting can cause irritation to human skin if it comes in physical contact.
They have the ability to produce eggs and sperm on their own (they are hermaphrodites) and leave the eggs in the water, which then develop into young blue buttons.

Where does a blue button jellyfish live?
The blue button is known to live in oceans and seas and ends up on the beach sand due to the wind. They love to float on the surface of the water as they are almost flat when it comes to their body shape.
Even in deep water, they are found on the water surface. They are found in Indo-Pacific, Australian, and Atlantic Oceans.

How do they reproduce?
The blue button jellyfish (Porpita porpita) are hermaphrodites i.e., they have both male and female sex organs and can produce eggs and sperm on their own. The mature polyps release eggs and sperm into the water, which fertilize on their own.
After this, they turn into larvae which further develop into young polyps. The egg count is said to be under 100, and only the larvae that survive fertilization develop into adult polyps. The cycle then goes on.
What is their conservation status?
Porpita porpita, which has a hydroid colony, is a species whose status is Not Evaluated. These jellyfish are generally found in the Atlantic Ocean and on the coast. This species, however, has been rapidly increasing in numbers due to rising temperatures across the world.
