Bathyceratias
''Bathyceratias trilynchnus'', the three-starred anglerfish, is a hypothetical species of anglerfish observed by William Beebe while in his bathysphere on 11 August 1934, at a depth of 2,470 feet (750 metres) off the coast of Bermuda. Description Beebe first witnessed the fish from a distance, with its light faintly reflecting on its back. Getting a clearer view once it swam into the beam of his bathysphere, it was described as similar to ''Ceratias'' and ''Cryptopsaras'', but with a flattened mouth and short, even teeth. It was ovoid, black in color, six inches in length, and possessed three illicium, each tipped with a pale yellow light organ. Current status As with the other four species described by Beebe during his bathysphere dives, the three-starred anglerfish has not been observed since.

Hypothetical Species
Several species have been assumed to exist, but due to a lack of physical evidence they can only be regarded as potential species. Hypothetical species are usually believed to be extinct. They have caused confusion, as they may have been a separate species, a subspecies, an introduced species or a misidentification.

Bathysphaera
''Bathysphaera intacta'', or the giant dragonfish, is a hypothetical species of fish described by William Beebe on 22 September 1932, having been spotted by the biologist as he descended to a depth of 640 metres (2100 feet) off the coast of Bermuda. Background Beebe's bathysphere was a new yet primitive invention. It was a rounded steel enclosure with space for two people, its external layer being 3 centimetres thick. On the side, there was a single window fifteen centimetres across. It was fitted with a heavy steel door that had to be bolted on. With no maneuverability, navigation of the bathysphere was dependent on the ship it had been attached to. Beebe used this submersible in his deep-sea expeditions from 1930 to 1934. The encounter Beebe encountered two fish, which he had described as "six feet long". He said they resembled barracudas, with short heads and jaws that were constantly opened, and that they were bioluminescent Bioluminescence is the emission of light d ...

Bathysidus
''Bathysidus pentagrammus'', the five-lined constellation fish, is a hypothetical species of fish that was described by William Beebe on 11 August 1934, being spotted by the biologist as he descended to a depth of 580 metres (1900 feet) off the coast of Bermuda. Background The "bathysphere" was a new invention, being a rounded steel enclosure with space for two people, a thick external hull, and a single window, in diameter. Maneuverability was solely dependent on the ship it was tethered to. Beebe had no camera with him and instead described the species in detail to Else Bostelmann, an artist who proceeded to illustrate his findings. Encounter The fish was seen in solitude. It was described by Beebe as resembling a surgeon or butterflyfish. It was disc-like in appearance, with a 12 cm high and 15 cm across. Its fins were continuous and vertical; its eyes large. Bebe was intrigued by this fish's striking bioluminescence, which he described in the book ''Half Mile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathyembryx
''Bathyembryx istiophasma'', the pallid sailfin, is a hypothetical species of fish observed by William Beebe on 11 August 1934. He described seeing the species twice during the same dive at depths of and near the coast of Bermuda. Background The "bathysphere," as termed by Beebe, was a new yet primitive invention. It was a rounded steel enclosure with space adequate for two people, its external layer being . On the side, there was a single window made of fused quartz, across and thick. It was fitted with a heavy steel door that had to be bolted on. With no manoeuvrability, the navigation of this steel submersible was solely dependent on the ship it had been attached to. Beebe had no camera brought with him to these great depth, and instead described the species in detail to Else Bostelmann, an artist who proceeded to illustrate his findings. From 1930 to 1934, this submersible was used by Beebe in his deep-sea expedition. The encounter Beebe had begun to fathom what he had ...
