The seadevil, Ogcocephalus, enters the LRT, not with anglers or frogfish, but with nearby gobies

According to Wikipedia,
“Ogcocephalidae is a family of anglerfish specifically adapted for a benthic lifestyle of crawling about on the seafloor.”

By contrast,
in the large reptile tree (LRT, 1836+ taxa) Ogcocephalus (Figs. 1–3), nests with Elacatinus (Figs. 4,5), the neon goby… and these taxa are outgroups to anglerfish, like Lophius. Anglerfish and frogfish developed similar camouflages and lures by convergence.

Derouen et al. 2015 reported,
“the position of Ogcocephalidae within Lophiiformes, remain[s] poorly understood with previous studies showing conflicting, and poorly resolved results.”

That’s what happens
with taxon exclusion. No gobies were in their analysis. Derouen et al. 2015 also employed molecules in their analysis, which, as we know my now, is a hit-or-miss method at best. Too many false positives arise following DNA deep time studies. Better to stick with traits and expand that taxon list as in the LRT. Then your results will be well understood and resolved.

The published study by Derouen et al. 2015,
despite their considerable talents, turned out to be a complete waste of time, money and energy because it was not based on a valid phylogenetic context due to taxon exclusion. When amateurs can say this about professional studies, so often, it’s time to revamp the whole academic process. Universities: Let’s first concentrate on the overall view of vertebrate diversity, as documented in the LRT, then go back to focus on the smaller studies that draw our individual attention. Stop teaching myth and tradition. Get your family tree in order!
