They have short siphons and feed on suspended plant material and detritus.
It also, weirdly, reminds one of all sorts of artwork one has seen before: the installations of Mike Kelley; the placards, swathes of photocopied material and detritus of Thomas Hirschhorn.
The painting seems at first to represent a single, unified object, some kind of vortex or whirlwind that has sucked up the material and detritus of a half-century of painting into a looping, billowing expression of pure energy.
All of the "indigestible material" -- the detritus that didn't make it through the first time -- gets pushed through.
Dead Phragmites material (litter, detritus) provides food as well.
Maximum longevity: 3 years.Non-selective feeding includes oysters, clams, other benthic invertebrates, fishes, and plants material, also detritus and carrion.
The down and dead woody materials pool (detritus) essentially consists of coarse woody debris, fine woody debris, and stumps.
Analysis of detritus material from the large intestine yielded a 14C date of 41,700 (+700/−550) years ago.
The slugs are not eating; as decomposers, if they were eating they would be processing leaves, animal droppings, mushrooms or dead plant material, among other detritus.
But it is not the only place where a system of rotating ocean currents, known as gyres, concentrate floating material, particularly plastic detritus dumped into the sea or washed out from rivers.
