Both Lure Fjord and Lindåsosane to the inside give good living conditions for rare marine organisms: jellyfish, shellfish and fish. These include animals that migrated in after last the Ice Age, when the sea level was higher. Eventually, as the land rose, some of these populations became isolated.
Some decades ago, Veafjord and the currents in toward the bigger rivers were the most likely places to see harbour seals in Hordaland. In the summer flocks lay on the beach and waited for the salmon to trickle in. Sometimes they also followed the fish a little way up the river.
Oselvo is the biggest waterway on the Bergen peninsula, with sources in Gullfjellet and Sveningen. There is a fall of only 60 metres along the entire stretch from Samdalsvatnet Lake to the sandbank in Fusafjorden. It is rare to see a river like this in western Norway. There is salmon along this entire section of the Oselvo river.
