2. Their natural habitats are in the soil, in the silt that comprises the bottom sediment of streams, lakes and coastal waters and ocean, while some types are natural inhabitants of the intestinal tracts of mammals (e.g., horses, cattle, humans), and are present in their excreta.

3. A vertical pull on the anchor will result in the anchor breaking out of the bottom sediment and is used as a technique to break the anchor's hold allowing the anchor to be raised in order to leave the anchorage.

4. One thought is that this trilobite may have lain in wait for prey buried in the bottom sediment with only its periscope eyestalks protruding.

5. Typically, the oil layer is skimmed off and subsequently re-processed or disposed of, and the bottom sediment layer is removed by a chain and flight scraper (or similar device) and a sludge pump.

7. This species probably uses its snout to probe for food in the bottom sediment.

8. The long snout of the sixgill stingray is very flexible both vertically and horizontally, suggesting that the ray uses it to probe for food in the bottom sediment.

9. A water column is a conceptual column of water from the surface of a sea, river or lake to the bottom sediment.

11. Research has also shown that the removal efficiency depends not only on the contaminant, but also on the "hydraulic and chemical characteristics of the bottom sediment and the aquifer, the local recharge-discharge conditions, and biochemical processes".

12. The tallow would bring up part of the bottom sediment (sand, pebbles, clay, shells) and allow the ship's officers to better estimate their position by providing information useful for pilotage and anchoring.

17. One of the main forms mentioned is fin contact with the bottom sediment, raising particulate material into the water column and degrading visibility.
