The spotted lanternfly (SLF) isn’t hard to recognize – adults can reach sizes up to 1.5 inches in length and the insect sports two, large, grey and black-spotted wings. And trust me they are coming!īut more importantly – if you think like me – there’s also consideration of what the lanternfly could mean for fishing. In speaking with several residents in my hometown in New Jersey, I’m realizing that many folks are completely unaware of what is coming and what it could mean for the state’s vegetation, as well as the potential economic impact associated with the arrival of the spotted lanternfly. Of more concern is the fact that they are beginning to spread into surrounding areas and neighboring states, including New Jersey. As a current graduate student in Philadelphia, the epicenter of the spotted lanternfly invasion, I have witnessed firsthand how invasive these bugs are, as they now litter the city and all the suburbs around it.

Version 3 November 2005 (under construction). ^ a b Froese, Rainer Pauly, Daniel (eds.) (2008).The only other deep-sea anglerfishes that have a hyoid barbel are the linophrynids, where it occurs only in the females and is often elaborate and/or bioluminescent. The function of the hyoid barbel in the horned lantern fish is unknown.

A female horned lantern fish has been found with a parasitic male Melanocetus johnsonii attached, though the coupling was likely in error (possibly occurring while the two fish were in the net) and there was no fusion of tissues. Similar to other ceratioid anglerfish, the males of the horned lantern fish undergo sexual parasitism. Unlike other deep-sea anglerfish, female horned lantern fish have only a single ovary lined with villi-like epithelial projections rather than epithelial folds. The two known larvae measure 4.2 mm and 7.5 mm long and have short, stout bodies with moderately inflated skin. Their hyoid barbel distinguishes them from the males of all other deep-sea anglerfish. The known specimens are all immature, though already with large olfactory organs and well-developed denticular plates on the tip of the snout bearing 3-4 curved teeth each. The males are much smaller and dark brown in color, measuring up to 1.6 cm (0.63 in) long and lacking the illicium and esca. There is a small hyoid barbel, although it is vestigial in adult females. The esca has a fan-shaped appendage in front and another short appendage on the back the tip is white with scattered large melanophores. The illicium ('fishing rod') and esca (lure) are attached to the snout.

The fish is reddish brown to black in color its skin is covered with numerous close-set spines. The eye itself lies beneath the skin and appears through a translucent patch. There is a large oval pit in front of each eye in specimens larger than 42 mm. The jaws are filled with slender, recurved, depressible teeth of mixed large and small sizes. The female horned lantern fish measures up to 23 cm (9.1 in) in length and is long and slender, with a large head and jaws of equal length. Specimens were caught at depths from 650 to over 2000 m (2130–6560 ft), while larvae have been recovered close to the surface to a depth of 35 m (115 ft). Specimens have also been captured in other locations, including New Guinea, the South China Sea, Venezuela, and the Mozambique Channel, suggesting a wide oceanic distribution in tropical and subtropical waters. The horned lantern fish occurs in the Pacific Ocean from Baja California south to the Marquesas Islands and the Gulf of California. It is the sole species in the family Centrophrynidae, distinguished from other deep-sea anglerfishes by various characters including four pectoral radials, an anterior spine on the subopercular bone, and a short hyoid (chin) barbel in both sexes. The horned lantern fish or prickly seadevil ( Centrophryne spinulosa) is a deep-sea anglerfish found worldwide.
