The following account is a synthesis of current knowledge on the barbels/tentacles of an array of submammalian forms and for the first time compares and contrasts their structure and function. In addition, the extensive background information on the homology and phylogeny of these structures is reviewed and evaluated. 
Structure of Barbel in Cyprinidae ( )
This fish had barbels with taste buds, smooth muscle, blood vessels, nerves and the center was without skeletal support.
Anatomical Features of the Pelvic Girdle in the Family Ateleopodidae(Pisces: Ateleopodiformes)
The osteology and myology of the pelvic girdle in a deep sea ateleopodiform fish, Ateleopus japonicus, were studied and suggest that this fin may not function in swimming, but may function in other actions such as searching for prey or signaling.
Subcortical barrelette-like and barreloid-like structures in the prosimian galago (Otolemur garnetti)
A distinct array of barrelette-like and barreloid-like modules are shown in the principal sensory nucleus, the spinal trigeminal nucleus, and the ventroposterior medial subnucleus of the galago, Otolemur garnetti.
Chemokine C-C motif ligand 33 is a key regulator of teleost fish barbel development
expression analysis indicated that paralogs of the ccl33 gene have both shared and specific expression patterns, most notably expressed highly in various parts of the head, such as the eye, brain, and mouth areas, supporting its role for barbel development.
FGF- and SHH-based molecular signals regulate barbel and craniofacial development in catfish
The developmental processes of Amur catfish are consistent with those reported for other catfish species and developmental aspects of craniofacial structures and taste buds may be conserved in Siluriformes, suggesting SHH and FGF signaling plays key roles in the ontogenesis and evolution of some catfish-specific characteristics.
Interactive Use of Barbels by Spotted Goatfish Pseudupeneus maculatus (Bloch, 1793) on the Reef of Bonaire, Lesser Antilles
Observed use of barbels by goatfish differs from their common uses in feeding, and from their previously noted use in courtship, and suggests an interpretation for the latter.
Morphometry and microanatomy of the barbels of the common sawshark Pristiophorus cirratus (Pristiophoridae): implications for pristiophorid behaviour.
The internal anatomy of the barbels of the common sawshark Pristiophorus cirratus was examined with light microscopy to clarify their sensory role and it is hypothesized that the Barbels are used by P. Cirratus to locate prey in both the water column and on the substratum via wake detection and sensing changes in surface texture.
Microscopy and classification of barbels of silver catfish Rhamdia quelen, Siluriformes, Pimelodidae
The goal was to describe and classify the microarchitecture of barbels of the silver catfish Rhamdia quelen, which can be classified in group 2B, along with fishes of the families Clariidae and Ictaluridae.
Anatomical structure, and expression of CCL4 and CCL13-like during the development of maxillary barbel in Paramisgurnus dabryanus
Results indicated that CCL4 and CCL13-like were related to the development of the maxillary barbel in Paramisgurnus dabryanus.
Genetic lineage labeling in zebrafish uncovers novel neural crest contributions to the head, including gill pillar cells
The data point to a crucial role for the NC in enabling more efficient gas exchange, thus uncovering a novel, direct involvement of this embryonic tissue in the evolution of respiratory systems at the protochordate-vertebrate transition.


A Study on the Barbels of a Marine Catfish, Arius thalassinus (RÜPP.)
A great variety of marine and fresh-water fishes possess externally situated appendages, the barbels. These are accessory feeding structures that carry sensory organs and thus seem to play an useful
Ultrastructural evidence for a possible secretory function of Merkel cells in the barbels of a teleost fish, Cyprinus carpio
Examination of barbels of the carp revealed cells showing the characteristics of Merkel cells, which suggest a secretory function in the carp.
Brain and sensory systems
A single cyprinid species, the goldfish, Carassius auratus, is one of the most intensely studied research models in neurobiology and biology in general. In contrast our knowledge of other cyprinids
Gross morphology and evolution of the mechanoreceptive lateral-line system in teleost fishes.

    Brain, behavior and evolution

The morphology and development of the mechanoreceptive lateral-line system in teleost fishes is reviewed, and it appears that the trunk canals may function as a hydrodynamic monitor in swimming fishes.
The Reproductive Biology of Caecilians: An Evolutionary Perspective

A number of aspects of the physiology and ecology of the group have adapted, so that features of the reproductive biology and life histories of caecilians provide considerable information of use in analyzing patterns of evolution.

Figures of Eberth are prominent extensive filamentous structures in the basal epidermal cells of larval amphibians. They are compared and contrasted qualitatively and quantitatively in a number of
Fine structure of the nasal barbel of the channel catfish, Ictalurus punctatus
Ultrathin sections of the nasal barbel of the channel catfish, Ictalurus punctatus, were studied in the electron microscope and the fine structure was compared to that of barbels of other teleosts
A Study of the Medulla Oblongata of Cyprinodont Fishes with Special Reference to their Feeding Habits
The purpose of this paper is to show that the cyprinodonts conform to this group of sight-feeding fishes, and an attempt is made to assign a definite position to the central acoustic area or lobe as a regional subdivision of the medulla oblongata.
Interrelationships of the ostariophysan fishes (Teleostei)
The extent of sympatry, together with the widespread distribution of ostariophysan lineages, suggests that the group is older than previously supposed, and hypotheses of relationships implies that many of the extent characiform lineages evolved before the separation of Africa and South America.
