That behavioral comparison itself suggests enhanced endothermy
for opah, says physiologist Robert Shadwick of the University of British Columbia in Vancouver, who wasn't part of the study.

results from vasculature with elaborate retia mirabilia (counter-current heat exchangers) that conserve metabolic heat and elevate oxidative tissue temperatures.
Fungal virulence, vertebrate endothermy
, and dinosaur extinction: is there a connection?
Except for the oceanic whitetip shark and silky shark clusters, which showed familial affinities based on phylogeny and life history, the topology of the dendrogram for pelagic shark species appeared to correlate with body size and latitudinal gradient, but not with phylogeny (Shirai, 1996), life history (Cort6s, 2000), ecomorphotype (Compagno, 1990), neural anatomy (Lisney and Collin, 2006; Yopak and Montgomery, 2008; Yopak and Frank, 2009), relative eye size (Lisney and Collin, 2007), or the presence of regional endothermy
(Bernal et al.
Once SRY evolved, endothermy
could also evolve since both males and females could develop at the same temperature.

First, the abundance of predator/prey ratio does not fit with the Eltonian Pyramid of Shotwell (1) or the predator/prey ratio for endothermy
in Bakker (5).
