De­bris ride ends in US

The Courier-Mail - - NEWS -

AL­MOST 300 species of fish, mus­sels and other sea crit­ters hitch­hiked across the Pa­cific Ocean on de­bris from the 2011 Ja­pa­nese tsunami, ar­riv­ing alive in the US, re­searchers re­ported on Thurs­day.

It was the largest and long­est marine mi­gra­tion doc­u­mented, out­side ex­perts and the re­searchers said. Their ar­rival could be a prob­lem if the crit­ters took root, push­ing out native species, the au­thors said in the jour­nal Sci­ence. It will be years be­fore sci­en­tists know if the 289 Ja­pa­nese species thrive in their new home.
