LIMULUS POLYPHEMUS Meaning and
Definition
-
Limulus polyphemus is a species of marine arthropod commonly known as the Atlantic horseshoe crab. These creatures are often referred to as living fossils due to their ancient lineage, with fossil records indicating their existence for over 450 million years. They are typically found along the Atlantic coast of North America, particularly in the United States.
The Limulus polyphemus possesses a distinctive horseshoe-shaped exoskeleton and a long spike-like tail. They have a hard, chitinous outer shell that provides protection, and their body comprises various segments. Horseshoe crabs have compound eyes on their carapace and use photoreceptors to detect light and movement.
These remarkable creatures have unique physiology, including blue copper-based blood, which helps in oxygen transportation and is utilized in biomedical research. They are known for their role in manufacturing limulus amebocyte lysate (LAL), an essential substance used to screen for bacterial contamination in medical devices and vaccines.
Limulus polyphemus play crucial ecological roles, serving as food sources for migratory shorebirds and some larger fish species. They also contribute to the health of coastal ecosystems by scavenging decaying organic matter and disturbing sediment, which promotes oxygenation.
Although not typically targeted by commercial fisheries, horseshoe crabs are sometimes used as bait and harvested for their blood. Their population has experienced significant declines due to habitat degradation and over-harvesting, raising conservation concerns. Efforts are underway to protect these ancient creatures and ensure their sustained existence in the wild.

Etymology of LIMULUS POLYPHEMUS
The term "Limulus polyphemus" is a species name in the scientific classification system, also known as the binomial nomenclature. It consists of two parts: the genus name "Limulus" and the species name "polyphemus".
