I’m not sure if this is allowed as a one off post, but I’ve been trying to identify this Echinoid I found in Turks and Caicos and I can’t find a species name and I was wondering if anyone knew it, thanks  it’s a beast

Hi,

 

We would need pictures showing the fasciole (the line circling the ambulacres), below and in profile to advance in the identification. It could be a Metalia, but also something else too.

Looks a lot like the test from the Red Heart Urchin, Meoma ventricosa.
