Beware of the jellyfish! An introduced ctenophore (Mnemiopsis leidyi) in a lagoon system in southeast France, a non-native pelagiid jellyfish (Chrysaora) in the easternmost Mediterranean Sea, and the white-spotted jellyfish (Phyllorhiza punctata) in Libya found through social media data mining.

 Fish news! Africa is no longer free of the non-native sailfin molly (Poecilia latipinna). Rice pairs well with the hybrid blood parrot cichlid in an agroecosystem in Malaysia. The twobar seabream (Acanthopagrus bifasciatus) in the Mediterranean Sea, a ship-born introduction?

Weedy business! Information to predict future distributions and target management efforts towards sites at high-risk of invasion by balloon milkweed (Gomphocarpus physocarpus). Two new alien weed species in Croatia (Amaranthus tuberculatus) and Poland (Cardamine occulta). Potential ecological consequences of the delta arrow (Sagittaria platyphylla) in Yangtze River.

 Many more first records… The plumose sea anemone (Metridium senile) from the Falkland Islands, the Red Sea gastropod (Nerita sanguinolenta) from the Israeli Mediterranean coast. Will the Carpathians remain free from the spiny cheek crayfish (Faxonius limosus)?
