Rare trophic eggs behind the success of snakehead fish?
15.03.2022
Fish rarely feed their young. An exception are certain species of snakeheads whose offspring feed on trophic eggs provided by their parent. A new study shows that this exceptional adaptation developed in snakehead fish around 12 million years ago. This behaviour might have enabled the fish to conquer new environments and led to the high diversity of species seen in one particular group of snakeheads.
