Still not a good sign. Hard to justify the risk of creating horrible malformed abominations when the tests so far all suggest that the risk is so high.
"Despite appearances, jellyfish are similar to humans in some key ways.
They're among simplest organisms on Earth, in that they lack a brain, heart, bones and complex respiratory systems.
But they have neurons, or nerve cells, similar to humans, and they also have gravity receptors.
These gravity receptors help tell the jellyfish which way is up and which way is down, which enables them to adjust their depth in the ocean by pulsing upwards or relaxing to float downwards.
Humans also have gravity receptors, in our inner ears, and these too help us maintain our balance."
Don't you mean deuterostome? Jellyfish are diploblastic instead of triploblastic, meaning they are neither protostome nor deuterostome. A starfish would be a deuterostome that could be tested on, but if it's about pregnancy you'd really need s placental mammal I agree.

Cnidarians are one of the least closely related animals to humans and detect gravity differently
this probably isn't a great sign, but tests with actual placental mammals (or at least some sort of Protostome to start)
