Sebastian Kvist is the Royal Ontario Museum's curator of invertebrate zoology, and a Professor of Evolutionary Biology at nearby University of Toronto.[1] He specializes in leech biology.[2]

In 2016 Forbes magazine quoted Kvist when identifying a "mysterious purple orb", found during the deep descent of a research submarine.[3] Kvist said he thought it was a pleurobranch, a soft-bodied marine mollusc.

In 2017, Kvist was one of the scientists who classified Websteroprion Armstrongi, a long marine worm, with a toothed jaw that snapped shut on prey.[4]

In June 2016 a compelling video of an exotic marine worm, rapidly everting a long proboscis, went viral.[5] Kvist was called upon by Earth Touch News to identify the worm, and its behaviour. He identified it as a member of the phylum Nemertea, and said the worm was dying, probably from the stress of being taken out of the water.

In December 2017 Popular Science quoted Kvist on what happens when one is bit by a leech, how to prevent being bit by a leech, how to remove leeches that have bitten you, and the gruesome situation of swallowing a live leech.[6]

In June, 2019, he was called upon to classify 5,000 contraband leech seized from a smuggler.[1]

Kvist earned his undergraduate and Master's degrees at the University of Gothenburg.[7] He earned his PhD in 2012 at the Richard Gilder Graduate School, American Museum of Natural History.[8][9]

"The leeches were taken into custody and sent to the Royal Ontario Museum where they were identified. According to Sebastian Kvist, curator of invertebrate zoology, the species is identified as Hirudo verbana, one of the only two leeches regulated under wildlife trade. Kvist explains that these leeches have been protected from overharvesting because of their medicinal properties since 1823. However, this species is also considered invasive when brought to new locations."

When a leech does invade a person’s body, it usually belongs to the Praobdellidae family. These leeches are known for feeding through mucous membranes. In other words: they want to be inside you. 'The rest of the skin is much more unappealing to them,' Kvist says, 'although they probably would feed on your leg, if they were starved.'"
