That's Lepidosiren paradoxa. It's been known for a long time that it
has a huge genome, and that the other lungfish also have huge
genomes. In fact, it appears that Protopterus aethyopicus has an even
bigger one. So no huge surprise here, just greater detail on *why* it
has a huge genome.

Ah, I see it's actually the largest animal genome *sequenced so far*.
It may be the 4th or 5th largest, and possibly the second-largest to
get that way without polyploidy.

 
So it is interesting how you can look at a macroscopic organism
and not really tell very well - this has a long (base pairs)
genome and this one does not.
 
So exclude the slime molds and do not call them something like
ultra-polyploidal.
 
Are there some other organisms that have really long genomes
besides some lobe finned fish and some lungfish and some frogs?

 
Well, ferns are famous.
 

What is the shortest frog genome?  Are there any frogs with
genomes shorter than humans or even chickens?  Which ones are
those?

 
You should check out the animal genome size database. Lots of answers
there. Check out the graph showing animal genome size ranges. I'd post
it here but images don't work.
 
Anyway, there are frogs with smaller genomes than any mammal and
crustaceans with longer genomes than some salamanders.

Size isn't everything.
