Info

The intertidal tubeworm Spirobranchus kraussii was originally described from South Africa and has since been found in numerous subtropical locations around the world.
Accordingly, there is a whole range of occurrences, e.g. in WoRMS (Cape of Good Hope South Africa Gulf of Mexico, Indian Ocean, Madagascar, Mozambique, Red Sea and as Lesseps' migrant the Mediterranean Sea.
It is generally assumed that the wide distribution of the nominal species is the result of translocations by humans.

The research article "Not out of Africa: Spirobranchus kraussii (Baird, 1865) is not a global fouling and invasive serpulid of Indo-Pacific origin" provides a detailed, illustrated redescription of Spirobranchus kraussii, based on the historical types and fresh material collected in South Africa from the type area (Western Cape Province) and the eastern part of the country (KwaZulu-Natal Province). The description is accompanied by DNA sequence data.

A more detailed comparative study of morphological features and environmental requirements found in populations around the world has provided further evidence supporting the
status of this species as widespread in the Indo-Pacific. The scientists led by Dr. Carol A. Simon conclude that Spirobranchus kraussii is an intertidal species of the temperate/subtropical zone restricted to the southern African coasts.
Spirobranchus kraussii belongs to a globally distributed complex that includes some tropical rot and invasive species.
