The costs and benefits of larger brains in fishes
Journal of Evolutionary Biology, Volume 35, Issue 7, Page 973-985, July 2022., 2022 Traits associated with brain size across fishes. Abstract The astonishing diversity of brain sizes observed across the animal kingdom is typically explained in the context of trade‐offs: the benefits of a larger brain, such as enhanced cognitive ability, are balanced against potential costs, such as increased energetic demands.

, 2023 Holocephali Les chimères (Holocephali, Chimaeroidei) ne sont représentées dans la faune kimméridgienne de Fumel que par une unique épine dorsale décrite par Sauvage (Fig. 15B) qui n’a pas pu être retrouvée dans les collections du MBA. Cette épine, que Sauvage attribua au genre Ischyodus Egerton, 1843, est recourbée postérieurement et porte des ...

Vacchi's palatal organ: a widespread trait in Holocephali
Journal of Fish Biology, 2018 A palatal organ, possibly used for food sorting and processing, has previously been identified among the vomerine toothplates of the chimaeroid Chimaera monstrosa. In this study, the palatal organ was described in six additional species, confirming it is a widespread trait among holocephalans.

First Description of a Palatal Organ in Chimaera monstrosa (Chondrichthyes, Holocephali) [PDF]
The Anatomical Record, 2015 ABSTRACTChimaeroid fishes are the only extant Holocephali, a subclass of Chondrichthyes. We describe for the first time a well evidenced structure localized in the palate of the chimaeroid Chimaera monstrosa, here named a palatal organ (PO). Attention has been paid to the holocephalan head morphology, but there has been no mention of this particular ...

Late Cretaceous chimaeroids (Chondrichthyes: Holocephali) from Alabama, USA [PDF]
PaleoBios, 2014 Tooth plates of three extinct species of callorhynchid holocephalans, Edaphodon mirificus , E. barberi , and Ischyodus bifurcatus have been collected from Upper Cretaceous strata of Alabama. Of the two species of Edaphodon , E. mirificus is represented by isolated tooth plates as well as associated dentitions.
