Echiniscoides sigismundi is a species of marine tardigrade. 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]
