[14] Another study found cod in a herring spawning area with 20,000 herring eggs in their stomachs, and concluded that they could prey on half of the total egg production. [17] Fish also cannibalise their own eggs.
The bacterial symbionts are not found at consistent levels throughout stages of anglerfish development or throughout the different depths of the ocean. [22] Sequencing of larval organisms of the Ceratioidei suborder show an absence of bacterial symbionts, while sequencing of adult anglerfish showed higher levels of bioluminescent bacterial ...

The creatures were found in “absolutely lightless” areas of forest caves, researchers said. ‘Giant’ cave-dwelling creature — carrying 6 eggs — found in Ecuador. It’s a new species
Coastal demersal fish are found on or near the seabed of coastal waters between the shoreline and the edge of the continental shelf, where the shelf drops into the deep ocean. Since the continental shelf is generally less than 200 metres deep, this means that coastal waters are generally epipelagic .
Six small non-avian dinosaur eggs, no bigger than grapes, were discovered during a field study in Ganzhou, China, in 2021. These eggs now mark the smallest-ever found in the world.
