There's only one problem that stops this idea. The Sea Emperor is a filter-feeder, like a humpback whale, while the Sea Dragon is a geophagous predator, which means it eats rocks as part of its diet alongside large prey animals. My guess is that they shared a common ancestor that underwent divergent evolution, which is when a single species becomes two separate species based on the environment. For example, the Bengal Tiger and the Siberian Tiger are both identical in appearance yet are completely separate species, one built for the heat and the other for the cold. In this case, the Sea Emperor evolved to life in the open ocean while the Sea Dragon evolved to life in a volcano.

It's likely both species evolved to what they are now long before the Precursors arrived. The data bank entry even says that its forearms are evidence of divergent evolution from another species many generations ago.
