今日のテキスト FIRST VIDEO OF EELS SPAWNING

A Japanese aquarium has captured the first footage of conger eels spawning their eggs. Scientists say details of the mysterious spawning process could help them to preserve the freshwater eel in Japan. They hope to find a way to raise these endangered eels from eggs to ensure stable supplies.
Sumida Aquarium in Tokyo has been rearing conger eels since it opened in 2012. The eels are roughly 30 centimeters long and are found in warm oceans. The spawning was filmed at midnight.
The female eel twists her body and releases her eggs into the water. The two male eels release their sperm. The camera also recorded the female eels moving in a way typically seen before spawning. These movements are believed to induce the male eels to begin releasing their sperm.
An expert describes the video of the spawning as "epoch-making." He says there are more than 700 types of eels, but no one has ever witnessed an event like this before.
