The first sentence and one near the end are very concerning to me:

Haementeria ghilianii, commonly known as the Amazon giant leech, is one of the world’s largest species of leeches.

One of the largest, not the largest species. One of the largest. How much larger do they fucking get!?

Unlike jawed leeches who use rows of teeth to puncture skin, Haementeria ghilianii uses a 10 centimetres (3.9 in) hypodermic needle-like proboscis to feed.

A 4 inch needle for a mouth. Lovely.

In the 1970s, Dr. Roy Sawyer discovered two adult specimens in a pond located in French Guiana. One of these leeches, dubbed Grandma Moses, founded a successful breeding colony at UC Berkeley. This specimen produced 750 offspring.

Oh god it’s like Jurassic Park but infinitely more horrifying

I bet they’re delicious
