Depth range Low to high tide level. [details]Distribution New Zealand: Hutt River estuary (Wellington Harbour, North Island). [details] Etymology The specific epithet magniovata is composed by the prefix magni-, a Latin combining form of magnus, meaning 'large', 'big', or 'great', and the Latin word ovata, form of ovatus and meaning 'ovate' or 'egg-shaped', and refers to "the unusually large ova" of the species (Read, 1975: 402). [details] Habitat Estuarine river banks, from high to low tide levels, in poorly-sorted sandy mud, sometimes stiffened by roots of Juncus maritimus rush, in areas where normal river salinity may be as low as 0.5‰. [details] Reproduction From Read (1975: 402): "The reproductive region of mature specimens extends from setigers 16 or 17 to about setiger 30. In males the lateral coelom of this region is filled with sperm. Male specimens comprised only about 5% of the total numbers in the collections made. In females each reproductive segment, except for the last three or four, contains one or two very large orange oocytes (up to µm diameter) on each side of the body. On each segment there is also a pair of conspicuous white seminal receptacles, which terminate in a pair of close-set pores on the mid-dorsal surface [...], and may contain motile sperm. During preservation contractions of the body sometimes forced the soft, flexible eggs out through the body wall. Eggs were ejected through either the dorsal or ventral surface without visible sign of an exit aperture. All larval development occurs in the capsules of the egg string, without nurse egg nutritional support, and without any planktonic stage. Reproduction occurs all year round." [details] Type locality Hutt River, Petone, 0.5 km upstream of estuary bridge, east bank, in fork of drainage-channel junction, Wellington Harbour, North Island, New Zealand, Pacific Ocean (-41.2285°, 174.9015°).
