One who studies or is knowledgeable about shrimp; a caridologist or expert in shrimp taxonomy.
Formed from 'carid' with the suffix '-eer' (one who practices or specializes in). This occupational word is rare and mostly historical in scientific literature.
This word is charmingly obscure—it's what you'd call a scientist who specializes in shrimp, but most modern scientists just say 'carcinologist' instead, making 'carideer' a professional title that almost nobody uses anymore.
