Lots of information on fugu including complete draft sequence, annotations, comparative vertebrate genomics, phylogenies, publications, and information about the fugu genome project; has some very useful tools including annotation tools, an Ensembl mirror, and BLAST.
Sorting Permutation by Reversals and Block Interchanges (SPRING) is a tool for the analysis of genome rearrangements. SPRING takes two or more chromosomes as its input and then computes a minimum series of reversals and/or block-interchanges for transforming one chromosome into another. Phylogenetic trees based on the rearrangement analysis are also shown as part of the results.
