What claims? The only relevant claim being made is that the hollow tube has been sequenced. No other claim about that information has been made. The statement about the sea squirt's emulation of Christopher Reeve is a previously held opinion.
On the other hand, how do you fit this into the vertebrate/invertebrate split?
The squirt can also do things that we can't. It stiffens its adult body with cellulose, for example. Plants and bacteria use this tough molecule in their cell walls, and possess similar genes for making and breaking it.
Where are the lilies with the nerve cells?
A few other questions could be asked such as were are the descendants that turn from tadpoles to plant like creatures. How are they 'born twice'? Where are the ancestors and descendants of this creature if it is so unique? Also, why would such a whacked out creature survive some 500 million years with 'all this evolving going on'? NOt only survive - but have not changed in 500 million years! I thought species evolved all the time. Is that not what evolution is all about?
Problem with evolutionists, (and evolutionist reporters) is that they are so ignorant and lacking in common sense that they do not see that this organism strongly disproves evolution.
