It is a wolf eel with mutated limbs of the elderly and a ferocious predator in the sea.
I'm trying to rationalize my concept. In the dark ocean, wolf eels will agitate their throats and emit beautiful light to attract their prey. The folds of the body are similar to those of the Komodo lizard, which may be a clue to their evolutionary origin. As a marine creature, of course, it should have a streamlined body and fins.
What excites me most is that my wife has provided a very cool idea. The throat of wolf eel can be a beautiful translucent structure. It can hold the baby in the throat, safe and beautiful. This is a wise idea, thank my wife!
