"Ew! Calamari."
Jacob Kowalski's disgust at the parasite[src]

These parasites were a kind of magical creature that resembled a "spindly, waterborne spider", usually found living off water dragons.[1]


The appearance of this parasite

They could also be transmitted to humans, infecting their tear ducts — the best curative approach is, apparently, extraction using a pair of tweezers.[1] Their powerful venom caused human hosts to lose consciousness after a convulsive jerk if not adequately treated,[2] requiring several hours of rest for a full recovery.[1] There were eye drops, a bright green liquid, that can help with the symptoms,[3] but it seemed this was not an adequate, definite cure.


Yusuf Kama having one of these parasites extracted from his eye with tweezers

In 1927, Yusuf Kama was infected with one of these parasites that, Newt Scamander speculated, was probably transmitted to him from a water dragon living in his sewer hideout in Paris.[1] When Kama attempted to contain Tina Goldstein, Newt Scamander, and Jacob Kowalski, so that he could freely find and kill Credence Barebone, the parasite's venom caused him to collapse, allowing them to escape.[2] They took the unconscious Kama to Nicholas Flamel's house, where they managed to extract the parasite, much to Jacob's disgust.[1]

Behind the scenes

Though they are described as spider-like in the screenplay, Jacob compares them to "calamari", a general culinary name for dishes made from squid.
