HORSESHOE CRABS Meaning and
Definition
-
Horseshoe crabs are marine arthropods belonging to the class Merostomata and are commonly found along the Atlantic coasts of North America and the Gulf of Mexico. They have a distinctive horseshoe-shaped exoskeleton that provides them with protection and support. Their body consists of a cephalothorax (head and thorax) and an abdomen, with a long, pointed telson in the rear. These ancient creatures have been on Earth for more than 450 million years, making them one of the oldest living species.
Horseshoe crabs are not real crabs; they are more closely related to spiders and scorpions. They have blue-blood, which is of great interest to the medical field, as it contains a substance called Limulus Amebocyte Lysate (LAL) that is used to detect the presence of bacterial endotoxins in medications and medical equipment.
These fascinating creatures are primarily known for their breeding behavior. During spring and summer, they migrate to shallow coastal waters to lay their eggs. Males attach themselves to the females' backs using specialized claws and fertilize the eggs as they are being laid. Millions of eggs are produced during a single breeding season, only a fraction of which will survive to adulthood.
In recent years, horseshoe crabs have become valuable in biomedical research, as their immune system and unique biological features have the potential to provide insights and develop solutions for various medical issues. Additionally, their ecological role as bottom-dwelling scavengers helps maintain the health of coastal ecosystems. Conservation efforts have been implemented to protect their populations as they face threats such as habitat loss and overharvesting for bait and medicinal purposes.

Etymology of HORSESHOE CRABS
The word "Horseshoe Crabs" can be broken down into two parts: "horseshoe" and "crabs".
1. Horseshoe: The term "horseshoe" is believed to originate from the combination of the words "horse" and "shoe". "Horse" refers to the large, powerful animal belonging to the Equus species, and "shoe" refers to the protective metal coverings fitted to the hooves of horses. The distinct U-shape of the horseshoe, resembling the letter "U" or a crescent moon, is what gave rise to this name.
2. Crabs: The term "crabs" comes from the Middle English word "crabbe", which was derived from the Old English "crabba".
