A new species of Squatina, S. david, is described from the Colombian Caribbean. The differs all western North Atlantic angel sharks by lacking a mid-dorsal line thorns or enlarged dermal denticles, having an eye-spiracle distance larger than 1.5 times eye diameter, and each nasal flap with two rod-like barbels. Coloration grayish to brownish yellow, males are dark-spotted, females have abundant whitish spots. Squatina david nested within American clade sharks, being sister Brazilian species.
Abstract Two new species of Characidium , C. tatama and dule are described from the biogeographic Chocó region in western Colombia. Both supported by both morphological molecular data. San Juan River Pacific Atrato Caribbean portion Colombia distributed upper lower portions these basins. An extensive comparison with other trans‐ cis‐Andean was made, addition to delimitation, using COI sequences distinct methods (GMYC, ABGD, bPTP).
The fish family Haemulidae is divided in two subfamilies, Haemulinae and Plectorhynchinae (sweetlips), including approximately 17 genera 145 species. has a broad geographic distribution that encompasses contrasting ecological habitats resulting unique potential for evolutionary hypotheses testing. In the present work we have examined phylogenetic relationships of using selected representatives additional Percomorpha based on Bayesian Maximum likelihood methods by means three mitochondrial...
The relationship between habitat complexity and species richness is well established but comparatively little known about the evolution of morphological diversity in complex habitats. Reefs are structurally complex, highly productive shallow-water marine ecosystems found tropical (coral reefs) temperate zones (rocky that harbor exceptional levels biodiversity. We investigated whether reef habitats promote feeding locomotion systems grunts (Haemulidae), a group predominantly nocturnal fishes...
Se describe una nueva raya del género Hypanus Pacífico oriental tropical (POT) a partir de material colectado en el Colombia. La especie es única dentro por ser gran tamaño (125 cm ancho disco [AD]) con un romboidal forma pala, su anchura 1,0 1,1 veces longitud, hocico obtuso, rostro prolongado punta extendida, 29–30% AD, tres filas dentículos agrandados la parte media escapula, hilera central se extiende hacia atrás hasta aguijón caudal, cola larga, 2,2–2,5 estrechándose suavemente....
Oceans blanket more than two-thirds of Earth’s surface, yet marine biodiversity is disproportionately concentrated in coral reefs. Investigating the origins this exceptional diversity crucial for predicting how reefs will respond to anthropogenic disturbances. Here, we use a genome-scale dataset reconstruct evolutionary history wrasses and parrotfishes ( Labridae ), which rank among most species-rich ecologically diverse lineages reef fishes. We show that major labrid clades experienced...
Background. The Cortez Province (CP) is located in the transitional warm-temperate/subtropical region that allows ichthyological component inhabiting it to be a mixture of elements different biogeographic affinities. Since first systematic analysis fish fauna Gulf California 1960's major portion endemic species was recognized. Subsequently, total 31 new have been described CP. This study constitutes an amendment CP, including most relevant ecological attributes species, along with updated...
The fish belonging to Gerreidae are common representatives of the coastal ichthyofauna tropics and subtropics world. genus Diapterus has a neotropical distribution currently includes four species: two in Atlantic Ocean [Irish mojarra D. auratus Ranzani 1842 rhombic rhombeus (Cuvier 1829)] Pacific [short‐beaked brevirostris (Sauvage 1879) golden aureolus (Jordan & Gilbert 1882)]. This uncertain taxonomy based on remarkable dissimilar morphology . We evaluated phylogeny with statistical...
Speciation and the interactions between recently diverged species are thought to be major causes of ecological morphological divergence in evolutionary radiations. Here, we explore extent which geographical overlap time since speciation may promote marine species, represent a small fraction currently published studies about patterns processes speciation. A time-calibrated molecular phylogeny New World haemulid fishes, radiation reef shore fishes tropical West Atlantic East Pacific, reveals...

The anthropogenic modification of trophic pathways is seemingly prompting the increase jellyfish populations at expense planktivorous fishes. However, gross generalizations are often made because most basic aspects ecology and diverse interactions with fishes remain poorly described. Here we inquire on dynamics food consumption medusoid stage scyphozoan Stomolophus meleagris characterize traits diversity its symbiotic community.S. their associated fauna were sampled in surface waters between...
Abstract Avoiding recognition involves the use of extraordinary strategies, among which camouflage is most common. Crypsis, a usual form camouflage, involves, many other disruptive coloration that uses marks disguise contours creatures to hide it. Fish live on coral reefs have developed several cryptic strategies avoid risk detection. The blue‐spotted cornetfish, Fistularia commersonii , presents pattern dark bands give perception coloration; however, this strategy has not been characterized...
For the first time, almost half a century after its discovery and description, poorly known endemic gobiid fish Chriolepis lepidota was seen alive at Malpelo Island. During 12-day expedition on March 2017, 18 specimens of this species were observed photographed different depths by means SCUBA diving. Species maximum size habitat preference are herein documented. This sighting represents record in wild. Also, report increases our knowledge ecology biology an unknown species.
In functional ecology, morphology is expected to reflect function; however, occasional decoupling of these two can be found. the case feeding diversity diet or modes within a clade positively related morphological traits involved in performance. Parrotfishes are separated into main groups, “reef” and “seagrass” clade. Both groups have important differences their evolutionary history. Still, more interestingly, they ecological differences. The genera Scarus Sparisoma most specious...
