The Vexillum Rock Shell, Vexillate Jopas, or Ribboned Jopas, scientifically known as Vexilla vexillum, is a captivating species of marine snail belonging to the family Muricidae. These gastropods are renowned for their distinctive, elongated shells, often featuring intricate patterns and vibrant colors.
Description & Characteristics
The shell of Vexilla vexillum is typically elongated and slender, with a pointed spire. The surface of the shell can display a variety of colors and patterns, including bands of white, brown, orange, and red. This striking coloration is thought to serve as camouflage, allowing the snail to blend in with its surroundings. The maximum size of this shell is approximately 45 mm, making it a relatively small species within the Muricidae family.
Habitat and Occurrence
Vexilla vexillum is a marine gastropod that predominantly inhabits shallow-water regions, often residing on sandy or muddy substrates in the intertidal zone. It can also be found in the subtidal zone, a habitat characterized by continuous water coverage, up to a depth of 30 meters. This species prefers environments with moderate water movement, making it commonly found in areas subject to tidal currents.
Taxonomy
Vexilla vexillum belongs to the Class: Gastropoda, Order: Neogastropoda, and Family: Muricidae. The Muricidae family is a diverse group of sea snails, commonly known as murex snails, characterized by their often spiny or knobby shells. The genus Vexilla encompasses numerous species, known for their slender, elongated shells.
Feeding
Vexilla vexillum is a parasitic gastropod. This means it relies on other organisms, specifically other marine snails, for sustenance. The Vexillum Rock Shell attaches itself to its host snail and feeds on its tissues. This feeding strategy allows Vexilla vexillum to thrive in a variety of environments and compete successfully for resources.
