Phyllophryne
A smooth-skinned frogfish endemic to southern Australian waters.
Phyllophryne is a genus of marine ray-finned fish with only one species, Phyllophryne scortea. This fish goes by several common names: white-spotted anglerfish, smooth anglerfish, or smooth frogfish, and it lives only in the waters off southern Australia.
The genus was created in 1984 by ichthyologist Theodore Wells Pietsch III, who designated *Histiophryne scortea* as its type species. That species had first been described in 1918 by Allan Riverstone McCulloch and Edgar Ravenswood Waite, based on a specimen from Stansbury on Gulf St Vincent in South Australia. Experts disagree on its family placement: some put it in the subfamily Histiophryninae within the family Antennariidae, while others consider it part of the separate family Histiophrynidae. The 5th edition of *Fishes of the World* does not recognize subfamilies within Antennariidae, instead placing the family in the suborder Antennarioidei within the order Lophiiformes (the anglerfishes).
The genus name *Phyllophryne* combines *phyllon* (Greek for "leaf," referring to the many leaf-like skin flaps on the head and body) with *phryne* (Greek for "toad," a common suffix in anglerfish names, dating back to Aristotle and Cicero, who called these fish "fishing frogs" or "sea frogs"). The species name *scortea* means "leathery," describing the texture of the skin.
This fish has smooth skin without dermal denticles, and its second and third dorsal spines are not hidden beneath the skin. The seven inner rays of the caudal fin are forked, while the outer rays are simple. There is no caudal peduncle, and the rear margins of the dorsal and anal fins are not connected to the outer caudal fin rays by a membrane. Scattered fleshy appendages cover the skin. The illicium (fishing rod) ends in an oval esca (lure) with several filaments at its tip. Color varies from green, yellow, orange, and brown to dark gray or black, often with whitish mottles or spots. The dorsal fin has 7 to 9 soft rays, and the anal fin has 15 or 16 soft rays. The maximum recorded total length is 10 cm (3.9 in).
*Phyllophryne* is endemic to southern Australia, ranging from Green Cape, New South Wales, and Tasmania west to the Houtman Abrolhos off Western Australia.

Lore & Background
Phyllophryne was first proposed as a monospecific genus in 1984 by American ichthyologist Theodore Wells Pietsch III, with Histiophryne scortea as the type species. The species was originally described in 1918 by Allan Riverstone McCulloch and Edgar Ravenswood Waite from a specimen collected at Stansbury on Gulf St Vincent, South Australia. Some authorities place it in the subfamily Histiophryninae within Antennariidae, while others recognize it as part of the family Histiophrynidae; the 5th edition of Fishes of the World does not recognize subfamilies within Antennariidae.
The genus name Phyllophryne combines phyllon ("leaf")—referring to the many scattered cutaneous appendages on the head and body that resemble leaves—with phryne ("toad"), a suffix common in anglerfish genera. The specific name scortea means "leathery," describing the texture of its skin. The fish has the second and third dorsal spines not hidden under the skin, seven inner caudal-fin rays that are forked, and outer rays that are simple. Its skin is smooth with no dermal denticles, and it lacks a caudal peduncle. The rear margins of the dorsal and anal fins are not connected to the outer caudal-fin rays by a membrane. The illicium (fishing rod) has an oval esca (lure) with filaments at its tip. Coloration varies from green, yellow, orange, brown to dark grey or black, frequently with whitish mottles or spots.
Reader's Guide
Phyllophryne represents a distinct lineage within the frogfish group, notable for its smooth skin and leaf-like appendages that aid in camouflage among encrusting algae and sponges. The taxonomic uncertainty surrounding its placement—whether in the subfamily Histiophryninae within Antennariidae or as part of the family Histiophrynidae—reflects ongoing debates in anglerfish systematics. The species is endemic to southern Australia, ranging from Green Cape, New South Wales and Tasmania west to the Houtman Abrolhos off Western Australia. It is a benthic fish found in temperate waters on rocky reefs in bays, estuaries, and coastal environments, frequently hiding under rocks and among sponges. As a carnivore, it uses its esca to attract prey within striking distance of its large mouth. It is oviparous: the female lays eggs onto rocky surfaces, and the male tends the fertilized eggs by curling around them, protecting them between his tail and body. With a maximum total length of 10 cm, it is a small but ecologically specialized predator in southern Australian reef habitats.
