Anglerfish morphometric and genomic phylogeny 2025
Elizabeth Miller et al 2025
“worked with SAFS Associate Professor and Curator of Fishes, Luke Tornabene, and a multinational team including scientists from Scripps Institution of Oceanography, The University of Oklahoma, and Rice University, to combine genetic material that has been collected and stored from anglerfishes over many years by agencies such as NOAA and museums like the Burke. ““Think millions of years instead of a few hundred,” Elizabeth said.”
This quoted from publicity (citation below) announcing the paper.
“The team then paired this family tree with measurements of body and skull shape to ask how the diversity of anglerfishes evolved over time.”
The team’s cladogram got down to species level,
far more ‘specific’ than the LRT can possibly attempt.

“The family tree…showed that elongated anglers, such as the wolftrap angler, are closely related to “blobby” ones such as the footballfish. As they share a recent common ancestor, that means there was a short amount of time in between the blobby ancestor and that elongated shape they have today. “A high evolutionary rate implies a lot of change in a short amount of time,” Elizabeth said.”
See the ‘blobby’ footballfish in figure 3.
The only problem I could put my finger on was:
the team cherry-picked suprageneic outgroup taxa unrelated to anglerfish. That’s taking an unnecessary short-cut. The 2025 anglerfish study did not include fossil taxa.
In other words, don’t guess outgroup taxa when anglerfish ancestors are known.

Neilpeartia lived during the Early Eocene, so anglerfish evolution has that as a minimal starting point that could extend much further back in time.
