Manania handi is a species of stalked jellyfish found in the Pacific Ocean along the west coast of North America.

This species can be found in shallow waters at low tide on soft substrates such as seagrass (Phyllospadix), but the related M. gwilliami have also been recovered at depths of >10 metres.

This may reflect that intertidal specimens represent the fringes of a population that is typically more commonly found in the subtidal zone.

Manania handi is also described typically as green with cream coloured gonads and vivid white nematocyst vesicles.

[1] However the colour patterns of M. handi can vary from brownish-yellow to vivid green.
