Like other elasipods, Scotoplanes can be found in very large herds, aggregations of often many thousands of individuals (Gutt and Piepenburg 1991). These aggregations are not believed to be deliberate; rather, the animals tend to gather where food resources are abundant (Dave Pawson, in litt. December 2009). Pawson (1976, 1982) and others have shown that elasipods usually face into the prevailing current, so they can “smell” more palatable sediments and move upstream to better feeding sites. Thus, around carcasses of dead whales on the seafloor, thousands of Scotoplanes can be found, busily gulping down the sediments rich in organic matter derived from the decaying whales (Dave Pawson, in litt. December 2009).
