Some interesting new arrivals in the USA, courtesy of the USGS Nonindigenous Aquatic Species Alert System:
- Congratulations to Georgia, the recipient of the Australian tubeworm Ficopomatus enigmaticus - only the second record of this species on the East Coast of the US (discovered May 2006).
- As of August 2006, Maine's got yellow floating heart (Nymphoides peltata) - a whole ton of it covering a pond in Rockport. I guess it's not that surprising since until this record, Maine was the only state in the Northeast US without this aquatic plant.
- Wyoming's got an established population of red-rim melania (Melanoides tuberculatus) in Grand Teton National Park (since June 2006). The mollusk was apparently introduced to the US via the aquarium industry.
- Finally, and as usual, Puerto Rico brings us some new country-level records from the aquarium world:
