Our resident river restoration expert Theo Pike recently posted another installment of his Wandle Restoration series. Subtitled Aliens 2, it mentions amongst other invasive species, Killer Shrimp (Dikerogammarus villosus). Today, UK news channels reported the arrival of a new species related to the Killer Shrimp. You can read about the new invader, Dikerogammarus haemobaphes, on the BBC website. For more detail you could read an abstract at SpringerLink.
In short Dikerogammarus haemobaphes originates from the Ponto-Caspian region of eastern Europe around the Black Sea. And like its relative Dikerogammarus villosus, this shrimp is already common in western Europe where it arrived in the 1960s.
