Caption
In looking for the source of rat lungworm infections, investigators have noted an invasive half-snail/half-slug creature called a semi-slug that is capable of carrying a high concentration of rat lungworm parasites. Other carriers in Hawaii include the Cuban slug, the giant African snail and the marsh slug.
