A research study suggests a worm named after late-night comic Conan OBrien might be adding to the decline in Caribbean spiny lobster landings. (AI-generated picture of “worm that looks like Conan OBrien.” See a real picture of Carcinonemertes conanobrieni listed below.).
A nemertean worm, Carcinonemertes conanobrieni, discovered by a Clemson University biologist, is suspected to negatively affect the recreation of Caribbean spiny lobsters, thereby adding to their reduced numbers. The worms effect on the lobsters reproductive cycle could have considerable implications for the marine community and the lobster industry.
A species of nemertean worm found by a Clemson University marine biologist five years ago impacts the reproductive efficiency of Caribbean spiny lobsters, a critical types in the Caribbean Sea and the Gulf of Mexico.
Antonio Baeza, an associate professor in the Department of Biological Sciences, discovered the brand-new worm while researching adult behaviors of the spiny lobster Panulirus argus in the Florida Keys. Baeza good-naturedly called the worm Carcinonemertes conanobrieni after comedian Conan OBrien since of its physical characteristics– pale and long-bodied with a small tint of orange.
The worm has actually been discovered off the coast of the Colombian and West Indies.

Caribbean spiny lobsters, which get their name from the forward-pointing spines that cover their bodies, reside in the Atlantic Oceans subtropical and tropical waters as far north as North Carolina, in addition to the Caribbean Sea and the Gulf of Mexico. They are among the Caribbeans most commercially rewarding and environmentally substantial types.
Caribbean spiny lobster landings have actually decreased over the previous decade. Researchers do not understand why, although they have determined numerous possibilities– overfishing, decreasing water quality, global environment change, and environmental degradation.
A new research study published in the journal BMC Zoology shows the worm discovered by Baeza is likely a contributor, too.

Artisan fishers caught 90 egg-bearing spiny lobsters near Pueblo Viejo, Magdalena, Colombia, to figure out whether C. conanobrieni impacted embryo death, fecundity, and reproductive output in brooding women.
Of the 90 lobsters, almost 88% had either nemertean worms or worm cysts and egg masses.
Embryo death, suggested by empty pills and dead embryos, varied between 0% and 43.81% in infected gravid females. Embryo death was absent in non-infected gravid female lobsters.
Researchers also validated that the presence of the worm affected reproductive output.

We dont understand why yet,” Baeza said. “We understand the egg predator is affecting the population level, but we can not state for how much of a result yet, whether it will be disastrous or bad because we do not have that data yet.”.
Carcinonemertes worms have been accountable for the collapse of shellfish fisheries on the west coast of North America.
Caribbean spiny lobsters are important for the marine ecosystem since they are victim for lots of predators, consisting of sharks, big fish such as grouper and snapper, turtles, and octopuses. They are predators, too, and consume snails, clams, and crabs. The clams are part of a different tropic chain, so when lobsters eat them, they connect tropic networks and energy flow through the entire environment.
” An entire industry and seaside communities along the entire Caribbean basin depend on this species,” Baeza said.
Baeza stated if researchers can understand the occurrence of the egg predator and its effects, a modeling method might forecast future landings and notify those managing the fishery to minimize negative impacts.
In addition to Baeza, Clemson graduate student Natalie Stephens and researchers from Colombia and Chile added to the study. Their findings are detailed in the paper “The result of the egg-predator Carcinonemertes conanobrieni (Nemertea) on the reproductive efficiency of the Caribbean spiny lobster Panulirus argus.”.

A study recommends a worm called after late-night comedian Conan OBrien may be contributing to the decrease in Caribbean spiny lobster landings. The spiny lobster is a commercially profitable and ecologically substantial species in the Caribbean Sea and the Gulf of Mexico. A worm found by a Clemson University researcher is affecting its reproductive performance. Caribbean spiny lobsters are important for the marine environment because they are prey for lots of predators, including sharks, large fish such as grouper and snapper, turtles, and octopuses. The clams are part of a various tropic chain, so when lobsters eat them, they connect tropic networks and energy circulation through the entire environment.
