A previous observation suggested that a novel phenotype of lionfish supraocular tentacle is evolving rapidly in the Red Sea and Indian Ocean. We confirm the existence of this phenotype in high prevalence in invasive populations of lionfish in the Western North Atlantic. Observations of individual lionfish from the Atlantic populations indicate that supraocular tentacles are more prevalent on juvenile and young adult lionfish suggesting this characteristic is size specific and is not associated… 

Spatial analysis of the invasion of lionfish in the western Atlantic and Caribbean.

Oogenesis and spawn formation in the invasive lionfish, Pterois miles and Pterois volitans

TLDR
Using histological and laboratory observations, it is found no differences in reproductive biology between P. miles and P. volitans and these lionfish are asynchronous, indeterminate batch spawners and are thus capable of sustained reproduction throughout the year when conditions are suitable.

Genetic homogeneity of the invasive lionfish across the Northwestern Atlantic and the Gulf of Mexico based on Single Nucleotide Polymorphisms

TLDR
These findings suggest rapid genetic changes over space and time during the lionfish invasion, resulting in one panmictic population with no signs of divergence between areas due to local adaptation.

Geographic extent and chronology of the invasion of non-native lionfish (Pterois volitans (Linnaeus 1758) and P. miles (Bennett 1828)) in the Western North Atlantic and Caribbean Sea

The Indo-Pacific lionfishes (Pterois volitans [Linnaeus 1758] and P. miles [Bennett 1828]: Family Scorpaenidae) are the first non-native marine fishes to establish in the Western North Atlantic. The

Field guide to nonindigenous marine fishes of Florida

The purpose of this field guide is to provide information on nonindigenous (i.e., non-native) fishes that have been observed in Florida’s marine waters. Introductions of non-native marine fishes into

Reproductive Biology and Histological Study of Red Lionfish Pterois Volitans from Cuddalore, South East Coast of India

TLDR
The present investigation clearly showed that the assessment of size at maturity, fecundity, spawning behaviour and capacity of reproductive in Pterois volitans, shows there is the intimate relationship between the length of the ovary and its relativem weight.

Mitochondrial control region sequence analyses indicate dispersal from the US East Coast as the source of the invasive Indo-Pacific lionfish Pterois volitans in the Bahamas

TLDR
Results indicate that the source of the Bahamian lionfish is egg and larval dispersal from the United States east coast population, and support previous models of reef fish dispersal that suggest a low level of connectivity between the Bahamas and east coast of Florida.

Biology and Ecology of the Invasive Lionfishes, Pterois miles and Pterois volitans

TLDR
A synopsis of lionfish biology and ecology including invasion chronology, taxonomy, local abundance, reproduction, early life history and dispersal, venomology, feeding ecology, parasitology, potential impacts, and control and management is provided.

Evolution in Action-Peacock-Feather Like Supraocular Tentacles of the Lionfish, Pterois volitans – the Distribution of a New Signal

TLDR
A novel phenotype of this lionfish has started to evolve, which instead of the typical ray-like supraocular tentacles bears a pair of feather-like tentacles, one or both of which bear a sharply defined eye-mark, previously noted in this fish in the eastern Indian ocean.

Mitochondrial cytochrome b analysis reveals two invasive lionfish species with strong founder effects in the western Atlantic

Lionfish (Scorpaenidae, Pteroinae) are venomous predatory fish that are native to the IndoPacific region and have recently become established in the western Atlantic Ocean. Since the invasion was

Biological invasion of the Indo-Pacific lionfish Pterois volitans along the Atlantic coast of North America

The occurrence of lionfish Pterois volitans is reported from the western Atlantic Ocean. Adults were collected off the coasts of North Carolina, Georgia and Florida, and juveniles were collected

Pterois volitans and Pterois miles: two valid species

TLDR
Character differences in specimens of P. volitans from Western Australia and the southern Pacific are evident, but the status of these groups remains unclear, pending the collection of more material.

Further Evidence for the Invasion and Establishment of Pterois volitans (Teleostei: Scorpaenidae) Along the Atlantic Coast of the United States

TLDR
The life history of red lionfish, especially their reproductive biology and food habits, should be investigated along the east coast of the US to determine the potential impacts of this species on ecosystems they have invaded.

Abundance estimates of the Indo-Pacific lionfish Pterois volitans/miles complex in the Western North Atlantic

TLDR
The magnitude and extent of the invasive Indo-Pacific lionfish invasion off the southeast coast of the United States is examined by first, compiling reports of lionfish to provide range information and second, estimate lionfish abundance from two separate studies.

Less than a decade after being observed off Florida, the invasive Indo-Pacific lionfish is now widely distributed off the southeast coast of the United States. As a step towards measuring invasion
