Limpet teeth have beaten out the previous record-holder for the strongest biological material found in nature: spider silk. Researchers found the limpets' teeth contain goethite, which is a hard ...
Sea foam washed up or blown onto a beach. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

The hagfish is an eel-shaped jawless fish that lives at the bottom of the ocean and produces slime/silk consisting of tens of thousands of very thin protein threads very similar to spider silk.
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Mineral calcium carbonate most commonly presents as calcite in the ocean, and the majority of calcite is produced biologically in the upper layer of the ocean. CaCO 3 material is exported from the upper ocean to sediments on the ocean floor where it either dissolves or is buried. [44]

Most Chondrichthyes species only go as deep as the bathyal zone. [15] Creatures that live in the abyssal zone include: Tripod fish (Bathypterois grallator): their habitat is along the ocean floor, usually around 4,720 m below sea level. Their pelvic fins and caudal fin have long bony rays protruding from them.
In 2010, researchers found that alginate, the soluble fibre substance in sea kelp, was better at preventing fat absorption than most over-the-counter slimming treatments in laboratory trials. As a food additive, it may be used to reduce fat absorption and thus obesity. [ 53 ]
