Macroinvertebrates of south Western Australia’s salt rivers 3

Cyprididae Mytilocypris mytiloides

The SW is home to a high diversity of seed shrimps (Ostracoda) with over 200 species known. Sixty-five known species live in naturally saline inland waters, however many of them are not found in systems impacted by rising salty groundwater (secondary salinisation). Some species are only found in one or two wetlands and there are still many undescribed species. This makes it difficult to develop protection plans. The eggs of seed shrimps can survive in dried sediments for several years. This species occurs in brackish to saline water and is common in swards of the aquatic flowering plant Ruppia sp. The grid squares are 1mm2.
