Does a horseshoe crab have a shell?
Yes, but not the hard, firm type shell you would find on a conch or snail. It’s more of a fleshy substance, and softer. If the horseshoe crab get any type of cut or abbrasion, the fleshy type shell will become susceptible to fungi and bacteria, which eat away at the shell and can expose the shell to addional microbes which will eventually become fatal.
