Gastropods (snails), echinoderms (sea urchins and sea stars) and annelids (lugworms) were exposed to oil saturated sediments and assayed for AHH activity (17). Sediment was mixed with Venezuelan crude at a concentration of 0.2-0.5% and exposures were for one week (4°C) in a static system with water renewal at 2-3 day intervals. The aim was to determine if oil soaked sediments could induce AHH activity in some representative intertidal benthic organisms common to the subarctic waters of the North West Atlantic. Digestive gland homogenates from snails, sea urchins, and sea stars and a combination of intestinal and gill tissues from annelids were used in the enzyme assays. 

AHH activity was not induced in digestive gland tissues of snails, sea urchins, sea stars, or lugworms (Table I) or in hepatopancreatic or green gland tissues of either male or female lobsters (Table II).

Others polychaetes are considered to be sedentary because they stay in one place, waiting for food to come to them. Their bodies are often shorter than errant worms, with clearly defined regions. Like the sabellid worm in the lower color insert on page C-2, sedentary polychaetes spend their lives in tubes or holes and have developed a variety of special adaptations for feeding and breathing in these niches. Most of these worms consume plankton or other small material that is suspended in the water. Some species of sedentary polychaetes include the coiled tube worm, sand builder worm, trumpet worm, parchment worm, lugworm, and hard tube worm. 

Alkyl- and alken-l-enyl-diacylglycerides. Alkyl- and alken-l-enyl-diacylglycerides (V, VI) were encountered in both the tissues of the lugwoni Arenicola marina and in the intertidal flat sediment of the Wadden Sea (The Netherlands) where these lugworms live (15).
