World's biggest colony of ants being wiped out
World's biggest colony of ants being wiped out Construction of a new port at Ishikari Bay on the
island of Hokkaido, Japan, is destroying the world's largest known
colony of ants - Japanese red wood ants. The colony is 20
kilometres long and consists of an estimated 45,000 nests linked by
tunnels to form one supercolony. Professor Seigo Higashi has
studied the colony for 28 years and thinks that the colony itself
could be 1,000 years old. The construction of the new port is
covering the area of the colony and killing many of the ants. The
ants are not listed as an endangered species and so are not of
concern to the Japanese Environment Agency.
