In the pitch-black depths of the sea, it may not be swimmable, but scientists usually find exciting things.
According to Live Science, researchers were able to spot a swarm of 115 eels in the abyss zone of the ocean, 9,800 feet below sea level.
Scientists from the University of Hawaiʻi at Mānoa saw the massive crowd of cutthroat eels. According to researchers, the footage of the creatures shows the most significant number of deep-sea fish ever recorded at one time in the abyssal ocean.
The footage was shot right near an international mining hotspot.
Due to the scarce food supplies in the deep sea, researchers say it is rare to see such a large number of the same species in a single “herd.”
“Our observations truly surprised us. We had never seen reports of such high numbers of fishes in the sparsely-populated, food-limited deep-sea,” lead author Astrid Leitner, who conducted this work as a graduate researcher at the UH Mānoa School of Ocean and Earth Science and Technology (SOEST), said.
The discovery was published in the journal Deep-Sea Research Part I: Oceanographic Research Paper, where scientists say the astonishing sight took place in the Pacific Ocean between Hawai’i and Mexico.
Whether these eels are just visiting the area or staying for good is still unclear.
