Short description Morfologi

Trumpet-shaped, to 4 cm total length. Calyx longer than wide, indistinctly demarcated from stalk, with scattered nematocyst watts. Stalk short, from one-half to equal to the entire calyx in length; narrow, contractile, circular to quadrangular in cross-section; four-chambered throughout. Arms short, appearing as four interradial pairs. Secondary tentacles 15 to 25 per arm, capitate, outermost ones with enlarged basal glandular adhesive pads. Primary tentacles eight, similar to abaxial secondary tentacles but smaller: small, dark spot on adaxial side of each primary tentacle near margin. Mouth quadrate with frilled lips. Muscles as in Manania gwilliami. Subumbrellar nematocyst vesicles along margin, most numerous in perradii where they extend toward gonads. Gonads similar to those of Manania gwilliami. Color of subumbrella, calyx, and stalk translucent yellowish green. Four linear, interradial "windows" of lighter green outlined by a thin brown margin occur along almost entire length of calyx. Gonads cream colored. Suburnbrellar nematocyst vesicles vivid white.

Biologi     Ordlista (t.ex. epibenthic)

Length and depth based on type locality; to be replaced with better reference. Attached to sea grass Zostera sp. and algae in semi-protected subtidal habitats, often sympatrically with Stauromedusae of the genus Haliclystus; their coloration make them cryptic on sea grass (Ref. 3419).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae

Members of the class Scyphozoa are gonochoric. Life cycle: Egg is laid by the adult medusa which later develops into a free-living planula, then to a scyphistoma to a strobila, and lastly to a free-living young medusa.
