Ecology Summary - Carukia barnesi

Language:

Ecology of Carukia barnesi

Main Ref.	Courtney, R., S. Browning, T. Northfield and J. Seymour, 2016
Remarks	Despite being discovered to be causing Irukandji syndrome over 50 years ago, little is known on the ecology of its early life stage. Polyp stage is suggested to be found in estuarine habitats based on observed increase in asexual reproduction under low salinity conditions. Medusa is oceanic, typically found around coral reefs, islands, and along beaches with certain conditions. Species may live in areas with high degree of osmotic variation. Population stability was achieved at temperatures between 18 and 31°C; optimum temperature was at 22.9°C (Ref. 116835).
