In times of exacerbating biodiversity loss, reliable data on species occurrence are essential. Environmental DNA (eDNA) – DNA released from organisms into the water – is increasingly used to detect fishes in biodiversity monitoring campaigns. However, eDNA turns out to be capable of providing much more than fish occurrence data, including information on other vertebrates. A study, published in the open-access journal Metabarcoding and Metagenomics, demonstrates how comprehensively vertebrate diversity can be assessed at no additional costs.
For the first time, scientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harmed, and the candirus apparently derived no food benefit, scientists believe this association is commensalistic rather than parasitic. The research is published in the open-access journal Acta Ichthyologica et Piscatoria.
Named for Black Panther’s mythical nation of Wakanda, a dazzling new “Vibranium” Fairy Wrasse enchants with purple scales and a preference for deep, little-known mesophotic reefs up to 260 feet below the surface Africa has new purple-clad warriors more than 200 feet beneath the ocean’s surface. Deep-diving scientists from the California Academy of Sciences’ Hope […]
The new species is the only coral-reef fish that lives exclusively within the marine protected area, which was recently expanded by the President Scientists from the Bishop Museum, NOAA, and the Association for Marine Exploration published the description of a new species of coral-reef fish that they named in honor of President Barack Obama. The […]
In the midst of the ongoing IUCN World Conservation Congress in Honolulu, scientists from Bishop Museum and NOAA published a description of a new species of butterflyfish from deep reefs of the Papahānaumokuākea Marine National Monument in the remote Northwestern Hawaiian Islands, which was recently expanded by President Barack Obama to become world’s largest protected area. […]
Smithsonian Institution’s DROP project describes a tenth new fish species near the Caribbean island of Curaçao Discovered by scientists using the manned submersible Curasub in the deep-reef waters of the Caribbean island of Curaçao, a new scorpionfish species is the latest one captured with the help of the sub’s two robotic arms. Found by Dr. […]
As part of the Deep Reef Observation Project (DROP), initiated by the Smithsonian Institution, a new goby fish species was discovered in the southern Caribbean. Living at depths greater than conventional SCUBA divers can access, yet too shallow to be of interest for deep-diving submersibles, the fish will now be known under the common name […]
Unidentified since its discovery in 2007, a large fish species from Amazonia has failed to give out enough information about itself, leaving only insufficient hints about its genus. Nevertheless, three scientists have now recovered the missing pieces to puzzle out its mysterious identity. In their study, published in the open-access journal ZooKeys, they describe the […]
Posing a significant threat to the native biodiversity in Japan, specifically that of threatened aquatic insects, some alien fishes, such as the bluegill, have become the reason for strict prohibitions. All activities potentially capable of introducing the species into the wild are currently punishable by either a fine of up to 3 million yen for […]
A new weakly electric mormyrid fish genus of two new species has been described from only three specimens collected over a period of 13 years in the rivers of the Central African country of Gabon. The genus has been named Cryptomyrus, meaning ‘hidden fish’ in Greek, and is the first new genus to be described […]
