Environment: milieu / climate zone / depth range / distribution range
Ecology
Pelagic; brackish; depth range 0 - 1250 m (Ref. 116114). Subtropical; 78°N - 55°S, 180°W - 180°E
Circumglobal. This species is widespread in all the seas of the sphere, from the equator to the poles. Subtropical to polar.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 2 - 31 cm Max length : 50.0 cm WD male/unsexed; (Ref. 2376)
Maximum diameter: 50 cm (Ref. 358); Height, from 10 to 12.5 cm; diameter, being able to reach 40 to 50 cm (Ref. 363). Plane sunshade; comprising very many tentacles courts with the periphery. One counts 4 oral arms; and 4 sexual organs; of annular form or in the horseshoe shape very many radiate channels. Coloring: generally translucent, with slightly pink reflections, blue or purple; the sexual organs are more clearly colored red or pink (Ref. 358).
This species is being eaten by predators because of its high fatty acid content (Ref. 122155).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
High abundances of ephyrae during late autumn can be explained by the large number of poly disc scyphistomae preceding to the appearance of ephyrae (Ref. 3062). Polyps begin to develop in August-September, matures in October and dies in November (Ref. 3271). Budding doesn’t occur in winter months (Ref. 7721). Can live up to 2 years (Ref. 3049).
