The copepod from hell
Ich, flukes, and velvet parasites are terrible enough, but they're no where near as grotesques as what this poor dwarf goby is suffering from: a gnarly parasitic copepod literally sucking the life out of its host . And you thought you were having a bad day
Find me a cleaner shrimp, STAT!
You can literally see the copepod pumping out the blood from the goby! But as sad as we might feel for the little guy, it's pretty amazing to see the diversity of bizarre life found on coral reefs ... even if said life is a blood-sucking parasite.
