Abstract
We report the collection of a single larval specimen of Microdesmus longipinnis (Pink Wormfish) in September 2024 in the tidal Hudson River. This specimen, which is the northernmost record of this species, was probably transported north in the Gulf Stream. Meristics confirmed the identity of the species and link this specimen to a population from the west coast of Florida.
