The Crystal Jelly, Water Jellyfish – Aequorea victoria is a fascinating bioluminescent jellyfish species renowned for its distinctive, translucent bell and its remarkable ability to produce green fluorescent protein (GFP). This intriguing creature, often found in coastal waters, plays a significant role in marine ecosystems.
Description & Characteristics
The Aequorea victoria typically exhibits a bell diameter ranging from 10 to 20 centimeters. Its translucent, bell-shaped body is characterized by a distinctive rim of numerous, short tentacles. These tentacles are equipped with stinging cells called nematocysts, which they use to capture prey. Unlike many other jellyfish, the Aequorea victoria lacks a distinct manubrium, the structure that typically connects the mouth to the stomach.
Habitat and Occurrence
The Aequorea victoria primarily inhabits the coastal waters of the northeastern Pacific Ocean, ranging from Alaska to California. Its distribution extends into the epipelagic zone, the uppermost layer of the ocean that receives sunlight. This species is particularly prevalent in the waters of Puget Sound and the Strait of Juan de Fuca.
Taxonomy
The species Aequorea victoria belongs to the Class: Hydrozoa, Order: Leptothecata, and Family: Aequoreidae. This classification places the Crystal Jelly, Water Jellyfish within a diverse group of aquatic organisms, many of which exhibit unique adaptations to their marine environments.
Feeding
The Aequorea victoria is a carnivorous predator, feeding on a variety of small organisms, including crustaceans, fish eggs, fish larvae, and even other jellyfish. Its diet reflects its role as a significant component of the food chain, helping to regulate populations within its marine habitat.
