Jellyfish are fascinating creatures that can be found in oceans all around the world. But have you ever wondered what a group of jellyfish is called? Well, a group of jellyfish is actually known as a "smack" or a "bloom".

These gelatinous sea creatures float gracefully through the water, using their tentacles to catch prey and defend themselves from predators. They come in a variety of shapes and sizes, from small, transparent moon jellies to large, colorful lion's manes.

Despite their delicate appearance, jellyfish are actually quite efficient predators. Their tentacles are equipped with specialized cells called cnidocytes that contain venomous barbs. When a jellyfish's tentacles come into contact with prey, the cnidocytes shoot out tiny harpoons that inject venom into the victim, paralyzing it so the jellyfish can consume it.

Jellyfish play an important role in marine ecosystems, serving as both predator and prey. They are a food source for many marine animals, including sea turtles, fish, and even some birds. And they help control the populations of small fish and plankton by feeding on them.

Unfortunately, jellyfish populations are facing threats from human activities such as overfishing, pollution, and climate change. As a result, jellyfish blooms are becoming more common in many parts of the world, causing problems for fishing industries and coastal communities.

To help protect jellyfish and the ecosystems they inhabit, it's important for us to take action to reduce our impact on the ocean. This could include reducing our use of single-use plastics, supporting sustainable fishing practices, and advocating for policies that protect marine environments.

So the next time you see a group of jellyfish floating gracefully in the ocean, remember that they are not just beautiful creatures, but important members of the marine ecosystem. And now you know that a group of jellyfish is called a "smack" or a "bloom".
