| Biology |
Amphihaline species. Adults live in the sea, but not as far from the coastline as Petromyzon marinus. They also occur in estuaries. Ammocoetes live in detritus-rich sand or clay sediments. In autumn, adults commonly undergo reproductive migration from the sea to the rivers. During reproductive migration and reproduction, adults do not feed but instead utilize their lipid reserves and are known to undergo a considerable shortening of up to 27 per cent. They spawn in strong-current habitats of rivers and streams. Spawning takes place in pre-excavated pits in river beds, its depth between 50 cm and 1 m; after spawning the adults die. The blind ammocoetes larvae are filter feeders and live mostly buried in the river bed. Metamorphosis takes pl |
