  •  They are believed to be introduced by humans in these regions. They are hammer head flatworms. The hammer head worms are known for the distinctive size of their head.
  • They usually prey on earth worms. The H.covidum hammer head flatworm feeds on snails. They are capable of tracking their prey. Some other flatworm species also feed on mollusks.


  • These flat worms are generally found in warm parts of the world.
  • They are common in Asia, mainly in Russia, China and Japan.
  • They are transported by people by soil and also by plant trade.
  • This makes them an invasive species.

Physical features

  • They reproduce asexually.
  • That is, they give birth without a mate. They have both types of reproductive organs. The H.covidum measures 3 cm long. They grow up to 40 cms. They are invertebrates.

These worms ingest and egest through the same opening. The digestive cavity is used to in take the nutrients and the undigested food are sent out through the same cavity.


Some of the flat worms cause diseases in humans and animals. Cestodes is caused by tapeworms. They also induce huge losses in fish farms. They are seen as main threats to organic farming.


They can be used to control the population of snails. Hawaii had used flatworms to control the exploding population of African snails.
