Both new species were found in mesophotic reefs in the Caribbean.  Two specimens of the Pygmy Jawfish, a new species and genus,  were found 250m deep off Cuzumel.  It is only inch in length.  It is described as a new genus.   Despite occurring beyond the reach of most divers and collectors, the Curaçao Jawfish was already been made available to aquarists, collected by the Curaçao-based submersible Curasub.

A diving expedition off Easter Island, 60–150 meters beneath the surface (the “twilight zone”), reveal new species of fish and invertebrates.  In collaboration with SUBELAB Pontificia Universidad Católica de Chile, a scientific team from the California Academy of Sciences became the first divers to study mesophotic ecosystems off Rapa Nui.  An orange colored sea biscuit, and four fish collected are almost certainly new species.  California Academy of Sciences Ichthyology Curator Luis Rocha plans to give the fish all Rapa Nui names in honor of the local culture.

Fish, New Species March 24, 2017 at 1:07 pm

The Gulf of Mexico Research Initiative, or GoMRI, paid for the study along with numerous other projects in the wake of the 2010 BP oil spill.   The study, called the DEEP END, took three voyages out of Houma on the Megsknsi. Each voyage took three months and used specialized nets to take around 16,000 samples of fish from below 3,280 feet. The study discovered 60 species of fish that had never before been discovered in the Gulf. Most of them were species that had already been discovered but had not been known to live in the Gulf. Twelve were completelyRead More

Just over 44 millimeters from the tip of its snout to the base of its tail, the X. sofiae is relatively small for Xyliphius, a genus of banjo catfish native to South America. Described by Mark Sabaj of the Academy of Natural Sciences of Drexel University,  the new catfish “has two characteristics that are relatively rare among catfishes: the complete loss of its eyes and its pale — almost extreme lack of — pigmentation,” Sabaj said. “Most catfishes with similar features inhabit underground aquifers and other cave environments.”  The species is described from a single specimen  collected in the main channel of the Río AmazonasRead More

Fish, New Species March 3, 2017 at 1:53 pm

Scientists have discovered the first entirely cave-dwelling armored catfish of the Callichthyidae family in South America. The species has adaptations for living underground, including a lack of pigment and reduced eyes. Researchers think it may use tree roots for shelter and food. But surveys indicate the new species, Aspidoras mephisto, is restricted to two caves in an area devoid of official protection, and human pressures around its restricted habitat mean it may already be highly threatened with extinction.
