Horseshoe Crab Specimen in Transparent Case

Body length approx. 4.2 cm
Case: 5.9 x 4.6 x 2 cm

Comes in a transparent plastic bag within its case.
It is not sealed, so you can observe the underside perfectly!

This is a living fossil classified under Chelicerata, which includes spiders and scorpions.
It's interesting that the Wikipedia entry for Characteristics features an illustration by Kawahara Keiga, a Nagasaki painter from the late Edo period! :*+.\(( °ω° ))/.:+ It's super realistic, so please take a look!
I wonder if you can tell if this specimen is male or female lol
