The three-starred anglerfish (Bathyceratias trilynchus) was a cryptid deep sea fish seen once, off Bermuda in the Atlantic Ocean, during a bathysphere dive by William Beebe on 11 August 1934.[2][3][4] Beebe described it as a fairly small ceratiid anglerfish, distinguished by the presence of three bioluminescent escae, or "lures," rather than the usual one.[1]

Description[]

This 6 in (15 cm) anglerfish resembled the common genera Ceratias and Cryptosparas, with some important differences. Rather than the pronounced underbite seen in these anglerfish, it possessed a mostly-flattened mouth with short teeth of even sizes. Furthermore, while anglerfish famously sport a bioluminescent "lure," a modified fin ray known as a esca, this specimen featured three such escae, "each tipped with a strong, pale yellow light organ ... clearly reflected on the upper side of the fish." The third esca was thicker than the other two, but of the same length. From what Beebe could see, the general morphology, black colour, fins, and eyes were otherwise similar to those of Ceratias and Cryptosparas.[4]

Sightings[]

1934[]

From 1930 to 1934, Beebe and his colleague Otis Barton (1899 – 1992), based on Nonsuch Island in Bermuda, performed several pioneering deep sea dives in a bathysphere, an unpowered submersible designed by Barton. These record-setting dives allowed them to observe deep sea life alive for the first time. On 11 August 1934, at a depth of 2,470 ft (752 m), Beebe and Barton had begun to reascend from their maximum depth, and had left the bathysphere suspended for a tie rope to be cut, when this anglerfish appeared outside the window. Beebe, who was in constant telephone contact with Gloria Hollister (1900 – 1988) at the surface, described the new fish to her, intending to expand upon it later.[4]

New fish 6 inches long, with 3 illicia on head, big one in front and 2 behind it close together. Fish not very deep. Good view; will enlarge on this.

Beebe quickly penned a more detailed account of the sighting in his paper describing Bathyceratias trilynchus, and later in his book Half Mile Down (1934).[1][4]

A tie rope had to be cut and in this brief interval of suspension, extended by my hurried order, a new anglerfish came out of all the ocean and hesitated long enough close to my window for me to make out its dominant characters. I am calling it the Three-starred Anglerfish, Bathyceratias trilynchnus. It was close in many respects to the well-known genera Ceratias and Cryptosparas, but the flattened angle of the mouth and the short, even teeth were quite different. It was six inches long, typically oval in outline, black, and with small eye. The fin rays were usual except that it had three tall tentacles or illicia, each tipped with a strong, pale yellow light organ. The light was clearly reflected on the upper side of the fish. In front of the dorsal fin were two pear-shaped organs exactly like those of the common Cryptosparas. The paired fins escaped me. No pioneer, peering at a Martian landscape, could ever have a greater thrill than did I at such an opportunity.

Theories[]

The three-starred anglerfish resembled the common angler genus Ceratias (Public Domain).

Beebe classified Bathyceratias trilynchus as an anglerfish in the family Ceratiidae, related to, but distinct from, Ceratias and Cryptosparas, especially the latter genus.[1] Out of a variety of undescribed fish reportedly seen during the bathysphere dives, Beebe penned descriptions of just a handful: the three-starred anglerfish, the giant dragonfish (Bathysphaera intacta), pallid sailfin (Bathyembryx istiophasma), five-lined constellationfish (Bathysidus pentagrammus), and abyssal rainbow gar. Ordinarily unwilling to formally describe new species without extensive research, Beebe chose to assign taxonomic names to the most memorable of the fish he saw because he knew there would likely be no second chance. His written descriptions were verified by Barton,[5] and illustrations by Else Bostelmann, showing only characteristics of which he was certain, acted as "type specimens."[4] However, given the circumstances of the sightings and the lack of either physical holotypes or any later observations, Beebe has been accused of misinterpreting or inventing his abyssal fishes,[6] and unlike some of the controversial fish he described, Bathyceratias trilynchus does not appear on modern taxonomic lists.
