Poralia rufescens, family Ulmaridae, found in the depths of all of the oceans

Aurelia aurita

Ghost, phantom, or spirit? The giant phantom jelly is none of those things! Stygiomedusa gigantea is most commonly found at depths of 6,665 m (21,867 ft), making it a rare and haunting sight; so rare, in fact, that it's only been spotted 114 times in the last 110 years. Not much is known about this species, save that it's one of the largest invertebrate predators of the deep, reaching up to 1 m (3.3 ft) across and 10 m (33 ft) in length!

Поралия относится к роду медуз из семейства ульмаридовых. Это монотипический род, содержащий один вид -Поралия рыжеватая. Данная медуза имеет колокольчик около 9 см (3,5 дюйма) в диаметре с восемью щупальцами в центре и с 30 тонкими тонкими придатками по внешней стороне диска . При движении Поралия может принимать волнообразную форму, она то расправит свой колокол, пока он не станет совершенно плоским, или сомкнет его, пока он не станет похож на большой воздушный шар. Колокол медузы рыжего, красного или розового цвета, иногда издалека кажется коричневым.

Поралия - медуза пелагическая и обитает на большой глубине в большинстве океанов мира. Эта медуза очень хрупкая, и большинство поднятых для изучения экземпляров были повреждены.

Poralia belongs to the genus of jellyfish of the Ulmaridae family. It is a monotypic genus containing one species, Poralia rufous. This jellyfish has a bell about 9 cm (3.5 in) in diameter with eight tentacles in the center and 30 thin, spindly appendages on the outside of the disc. When moving, Poralia can take on a wave-like shape, either spreading out its bell until it becomes completely flat, or closing it until it looks like a large balloon. The bell of the jellyfish is red, red or pink in color, sometimes appearing brown from a distance. Poralia is a pelagic jellyfish and lives at great depths in most of the world's oceans. This jellyfish is very fragile, and most specimens raised for study were damaged.

Is it a placenta? Is it a jellyfish? NO! YES!

Deepstaria enigmatica, family Ulmaridae, order Semaeostomeae, class Scyphozoa

Usually found in Antarctic and near-Antarctic seas, but have been found in the Atlantic as far South as the Gulf of Mexico.

Usually found at depths of 600–1,750 m (1,970–5,740 ft).

This species is known to have symbiotic (possibly parasitic) isopods living in their bells.
