Echiniscoides sigismundi

provided by wikipedia EN

Echiniscoides sigismundi is a species of marine tardigrades. It lives in seaweeds[1] or plates of barnacles, or more generally in algal strongholds in inter-tidal areas.[2][3]

Taxonomy

Echiniscoides sigismundi is the type species of Echiniscoides.[4] Described in 1865 as Echiniscus sigismundii, it was placed in a separate genus by Ludwig Hermann Plate in 1888.

Distribution

By 1936, it was reported in most seas of Northern Europe, and in the Mediterranean and the Caribbean.[1]

The Light and Smith Manual[5] describes its distribution as cosmopolitan, in the upper inter-tidal.

Osmobiosis

Echiniscoides sigismundi becomes turgid in freshwater, but can survive up to three days, resuming normal activity as osmotic differential returns to normal.[6]

Distribution

provided by World Register of Marine Species
More recent molecular studies suggested that at least some of the subspecies should be elevated to species level. Due to the confusion and inclusion of different subspecies (and possible new species), it is not possible to identify the geographic distribution of this taxon.
