The Importance and Threats to Horseshoe Crabs
TLDR Horseshoe crabs, ancient creatures with unique appearances, have blood that is highly valuable for medical testing. However, the harvesting of their blood results in a significant loss of their population and could potentially lead to their extinction in Asia within a decade.
Timestamped Summary
00:00
Horseshoe crabs are ancient creatures that have remained virtually unchanged for 450 million years and have a unique appearance with a tough exoskeleton and six legs.
02:17
Horseshoe crabs have a unique appearance and are closely related to spiders and scorpions, and their blood can be used to identify harmful bacteria in medical samples.
04:33
Horseshoe crabs are a delicacy for shorebirds and their population is under strain due to human impact and the birds eating their eggs, particularly in Asia.
06:55
Horseshoe crab blood, specifically the clotting agent called LAL, is one of the most valuable fluids on earth, priced at $15,000 a quart, due to its supreme clotting abilities.
09:24
Horseshoe crab blood, which contains a specialized type of blood cell that clots around pathogens, can be harvested from the crabs and used in place of rabbit blood for testing, saving rabbit lives, but about 30% of the horseshoe crabs that are harvested and have blood drained from them end up dying.
11:34
About 30% of the horseshoe crabs that are harvested and have blood drained from them end up dying, which is a big problem because it results in a significant loss of the blood market and could potentially lead to the extinction of horseshoe crab species in Asia within a decade.
13:57
The use of synthetic Limulus Amebocyte Lysate (LAL) in testing medical devices could potentially eliminate the need for horseshoe crabs in the future.
