I recently spent a couple of evenings with NYC's Urban Park Rangers observing, counting, collecting data, and tagging Horseshoe Crabs. They are amazing animals, and I am more awed each time I see them.

@RickiTarr And commercial testing labs bleed them to exhaustion instead of using an equally effective synthetic purification product. Advocating for the old timey beach dorks #horseshoeCrabs #ancientBugs #beKind 🧲🦀 :crab_dancing: :people_hugging:

#HorizonZeroDawn is EIGHT years old.

#GhostOfTsushima is FIVE years old.

I am sooo old that I still think of both of these as "new" games hehehe

#HorseshoeCrabs have watched mountain ranges rise and fall. What's eight years if your species is nearly half a billion years old?

On conservation of the local mangrove and coastal horse­shoe crabs.

"Protecting and restoring mangroves, as well as establishing “coastal corridors” in areas where intensive development is ongoing, could help with the conservation of two of Asia’s mysterious seabed-dwelling organisms."

Protect Horseshoe Crabs 🦀

#HorseshoeCrabs are one of the most ancient #species on the planet: They've been here since before there were dinosaurs. But in the blink of an eye — in the past three decades — their #populations have crashed. #CommercialFishers chop them up for bait, and the #BiomedicalIndustry drains them of their blood for #MedicalTesting (even though safer synthetic alternatives are available).

on an evening beach walk, i encountered what appeared to be a shrine to the horseshoe crab. there were some shells arranged side by side, encircled by plant matter washed up from the ocean.

i paid my homage and kept walking #beach #HorseshoeCrabs #oceancitynj

Limulus polyphemus — horseshoe crabs — in South Dakota! Pretty cool, IMO. (As a seashore kid, I think horseshoe crabs are awesome.)

We encountered quite a few #HorseshoeCrabs today at #MonomoyNWR 💙🤗

A snapshot of the shallows of the sea at low tide. There’s a horseshoe crab in the foreground. And the distant ocean horizon with a sliver of overcast sky at the top. The water is clear and calm. Peaceful and relaxing.

500 million-year-old #fossil is the earliest branch of the spider’s lineage, a group that includes #spiders, #scorpions, and #horseshoecrabs.
A local fossil collector in #Morocco found the specimen decades ago. arstechnica.com/science/2024/0

Sooooo fear of spider's developed 500 million-years minus one day ago?

Horseshoe Crabs Have Been Hiding Out in the Marsh hakaimagazine.com/news/horsesh

The American horseshoe crab (Limulus polyphemus) spawns regularly in salt marshes esajournals.onlinelibrary.wile

"#scientists have long thought that beaches are the only suitable spot for these #animals to lay their eggs. But new research from across the eastern United States now shows that #HorseshoeCrabs spawn in #SaltMarshes at roughly the same rate"

The 5 to 10 millimeter long official first ancestor of scorpions, spiders, and horseshoe crabs from hundreds of millions of years ago was just described, named Setapedites abundantis, and is undergoing further study phys.org/news/2024-05-discover

An illustration of Setapedites abundantis, the 5 to 10mm long ancestor of scorpions, spiders, and horseshoe crabs. It looks kind of like a horseshoe crab mixed with a shrimp.

"Measuring between 5 and 10 millimeters in size, it has been named #Setapedites abundantis. This animal makes it possible, for the first time, to trace the entire lineage of #chelicerates, from the appearance of the earliest #arthropods to modern #spiders, #scorpions and #HorseshoeCrabs"

Reconstruction of Setapedites abundantis. By Elissa Sorojsrisom. The animals look a little like trilobites. They are swimming above a sandy sea floor.
