Common Names
There are no widely recognized common names for the species within the genus Pelagella.
Characteristics
Pelagella species are characterized by their small size, typically with a bell diameter of less than 1 centimeter. Their bell shape is often described as being flattened or discoid, with a smooth, transparent surface. They possess four radial canals and four tentacles. Pelagella jellyfish are known for their ability to contract their bell rapidly, enabling them to propel themselves through the water. Their coloration can vary, ranging from translucent to pale pink or yellowish.
Environments
Pelagella species are predominantly found in warm waters, with a distribution spanning across the Atlantic, Pacific, and Indian Oceans. They inhabit both coastal and oceanic environments, often dwelling in the pelagic zone, the open ocean waters. These jellyfish are commonly observed in plankton samples and can contribute significantly to the zooplankton community.
