The taxobox to the right describes Eoporpita as Mary Wade first did in 1972 as a Hydrozoa member and within the phylum Cnidaria.

Annular shaped chambers surround the central dome, similar in look to ring-shaped ripples in a water body.

[1] Wade interpretation: Eoporpita's aboral surface is the side with its central dome.

The 'tentacles' appear massed and stacked, with the fossil being tallest at the central dome and thinning out closer to its edges.

When describing Eoporpita in 1972, Mary Wade noticed slight similarities in their affinities.
