The Purple Jellyfish, Rasta Jelly, Pellagic Purple Jellyfish, scientifically known as Thysanostoma loriferum, is a captivating species of jellyfish renowned for its striking purple coloration and large size. This jellyfish, a member of the Scyphozoa class, is a significant component of various marine ecosystems, captivating both scientists and casual observers alike.
Description & Characteristics
Thysanostoma loriferum is easily recognized by its prominent purple hue, which can range from deep violet to a lighter lavender, depending on its location and age. These jellyfish can grow to a substantial size, with some individuals reaching a diameter of up to 3 feet. Their bell, or umbrella-shaped body, is characterized by a unique and intricate pattern of branching arms, giving them a distinctive appearance.
Habitat and Occurrence
Thysanostoma loriferum is a pelagic species, meaning it lives in the open ocean, often found in warm, tropical and subtropical waters. Its presence is typically noted in regions like the Atlantic Ocean, the Indo-Pacific region, and the Mediterranean Sea. These jellyfish are frequently observed in the epipelagic zone, which is the upper layer of the ocean that receives sunlight, although they can venture into deeper waters.
Taxonomy
The Purple Jellyfish, Rasta Jelly, Pellagic Purple Jellyfish (Thysanostoma loriferum) is a member of the Rhizostomeae order within the Scyphozoa class. This species belongs to the Leptobrachidae family, which encompasses a range of jellyfish species with varying morphologies and ecological roles.
Feeding
Thysanostoma loriferum is a carnivorous predator, primarily feeding on zooplankton, small fish, and other invertebrates. Its unique arm structure aids in capturing prey, as it is covered in tiny tentacles that contain stinging nematocysts. The jellyfish’s diet is further supplemented by zooxanthellae, microscopic algae that live in a symbiotic relationship with Thysanostoma loriferum, providing the jellyfish with energy through photosynthesis.
