[3] Adult specimens are approximately 3 inches (7.6 cm) long.

[3] Their diet probably consists mainly of a small red tubificid worm, Isochaeta israelis.

[4] The shrimp is endemic to one chamber of a Roman cistern, Ein-Nur octagonal pool (the private property of a monastery,[1] at 32°52′25″N 35°32′57″E / 32.8736°N 35.5493°E / 32.8736; 35.5493), and a warm (27 °C or 81 °F),[5] sulphuric,[5] saline[1] subterranean spring that feeds it, at Tabgha,[6] on the north shore of the Sea of Galilee in Israel.

[3] It is legally protected (Section 5, paragraphs D and E, of the Fisheries Rules of 1937 as amended).

[8] In 2013, the Israel Nature and Parks Authority approached the Jerusalem Biblical Zoo to develop a captive breeding programme for the species, with a view to later reintroduction.
