This time around, the otter is in danger of decline through perfluorinated substances, toxic materials that are used in waterproofing and can damage the liver and reproductive system.
"Analyses of 10 different fluorinated substances in otters show a dramatic increase from 1980 to today. The highest levels were extremely high, among the highest in the world," said Anna Roos, curator of Stockholm's Swedish Museum of Natural History (Naturhistoriska museet).
Environmental pollutants are not the only threats against the reserved animal. Many otters are run over in traffic. The Swedish Transport Administration (Trafikverket) has begun to build passages so otters can safely cross busy roads and bridges.
