"So, naturalists observe, a flea has smaller fleas that on him prey; and these have smaller still to bite ’em; and so proceed ad infinitum."

January 6 - Ichthyophthirius multifiliis
Ick! I guess that's a common thing people might say about parasites. Turns out that there's one called that, though it's usually spelled "Ich", short for Ichthyophthirius multifiliis. These parasites are ciliates, and they cause skin lesions and other issues in fish and are a bane of tropical fish hobbyists and aquaculturists alike.
