1A group of environmental organizations is seeking an official declaration that American horseshoe crabs are endangered.
2The groups have requested the declaration with the National Oceanic and Atmospheric Administration (NOAA).
3The U.S. agency administers the Endangered Species Act, which was established in 1973.
4The American horseshoe crab - known as a "living fossil" - is one of the oldest living creatures on Earth.
5It is believed to date back at least 450 million years.
6Scientists do not actually consider horseshoes true crabs.
7This is because they are more closely related to spiders and scorpions than to other sea creatures.
8If NOAA approves the endangered declaration, it would generally make it unlawful for people to harm or kill a horseshoe crab without an official permit to do so.
9Research suggests horseshoe crab populations in the U.S. have decreased sharply over the past 30 years.
10For example, growth numbers for the animals are down two-thirds from 1990 in an area of the Delaware Bay.
11Environmental groups say this body of water in the northeastern state of Delaware once held the largest population of horseshoe crabs.
12Research also shows that egg densities for the animals have fallen more than 80 percent over the past 40 years.
13The reproduction drops are linked to environmental changes causing other sea creatures to eat their larvae and eggs, researchers say.
14A collection of 23 environmental groups have joined to seek the endangered declaration.
15The request, or petition, also seeks the establishment of a "critical habitat" for horseshoe crabs to be protected.
16The request names numerous threats to the animals - all of which are blamed on human activities.
17These include harvesting the crabs to be used for bait, use in biomedical activities, habitat loss and climate change.
18A spokesperson for NOAA confirmed to Reuters news service the agency was examining the groups' petition, but did not comment further.
19Will Harlan is a senior scientist at the Arizona-based Center for Biological Diversity.
20He told Reuters, "We're wiping out one of the world's oldest and toughest creatures."
21His group is one of those seeking the endangered declaration.
22Drug manufacturers harvest horseshoe crabs in large numbers for their blue-colored blood.
23The blood is used to test and develop drugs and medical devices.
24The petition states that in 2022, nearly 1 million of the animals were used for medical purposes.
25Current law permits the biomedical industry to capture small amounts of horseshoe crab blood before releasing the animals alive to areas where they were collected.
26However, NOAA says between 10 to 15 percent of harvested animals die during this process.
27Harlan said non-industry research suggests this rate is even higher.
28Those estimates show that 30 percent of horseshoe crabs captured for blood collection die in the process.
29Harlan noted that while synthetic blood versions are widely used in Europe, American companies have been slow to use them.
30The petition says the other main cause of population drops is overharvesting of horseshoe crabs for commercial fisheries.
31Environmental activists say this is likely to continue, with no sign of recovery even after harvesting limits were established.
