Phacellophora
Phacellophora is a genus of scyphozoan jellyfish, also known as “flower hat jellyfish” and “crown jellyfish.” These fascinating creatures belong to the family Phacellophoridae, which is part of the order Rhizostomeae. Phacellophora is distinguished by its unique bell shape, which resembles a crown or flower, and its intricate, branching arms.
Characteristics
The bell of Phacellophora jellyfish is typically dome-shaped and can reach up to 30 centimeters in diameter. Its most striking feature is the intricate network of branching arms that extend from the bell's margin. These arms, known as oral arms, are covered in numerous, tiny tentacles that are used to capture food.
Phacellophora jellyfish lack the typical stinging tentacles found in other jellyfish. Instead, their oral arms possess specialized stinging cells called nematocysts, which are used to paralyze prey. The arms are also covered in sticky mucus that helps to trap food particles.
Unlike many other jellyfish, Phacellophora lacks a distinct mouth. Instead, they absorb nutrients directly through their skin.
Environments
Phacellophora jellyfish are found in tropical and subtropical waters around the world. They are typically found in open ocean environments, but may also be seen in coastal areas.
These jellyfish are known for their ability to migrate long distances, with some individuals traveling thousands of miles across the ocean.
