Mollusks is a large, diverse phylum of invertebrates. Types of mollusks range from small (snails and slugs) to large (octopus and giant squid).

What is green lipped mussel?

green lipped mussel

Green Lipped Mussel; Latin: Perna canaliculus, also known as Greenshell Mussel

Green Lipped Mussel is commonly made into a powder or oil form and used as a Supplement. It's unique properties help it to play a major role in the transfer of nutrients through the body, adding to the structural integrity of all body tissues. These nutrients are responsible for:

  • Elasticity of blood vessels
  • Youthful appearance of skin and hair
  • Act to lubricate joints
  • Allow the body to heal naturally
  • Help to overcome pain more quickly

What Do Mussels Eat?

What do freshwater mussels eat? • Fish, turtles, leaves? No - freshwater mussels eat microscopic plants and animals called plankton • They also eat bacteria and detritus (dead plant and animal pieces) suspended in the water.

How do freshwater mussels eat? • Freshwater mussels do not hunt or search for their food; they wait for it to come to them • Freshwater mussels filter feed by sucking water in through a siphon (kind of like a little hose) • Water passes over gills where food particles get filtered out and carried by little hairs called cilia to the mouth

Sea Urchins

What part of giant kelp do sea urchins eat?

Sea urchins eat the holdfast, the part of the kelp that holds the kelp to the seabed. Once the holdfast is consumed, there is nothing to anchor the kelp, which will then float to the ocean's surface and, eventually, die.

Sea otters are some of the most significant natural predators of sea urchins. But due to the depletion of sea otter populations by excessive hunting in the past couple centuries, there have been too few otters to control the levels of urchin population. Urchins have therefore been eating the kelp faster than the kelp can reproduce, in some locations. Many areas that once had large kelp forests have been eaten away until nothing is left, leaving behind regions known as "urchin barrens". This proves detrimental not only for the kelp, but also the multitudes of animals, ranging from other invertebrates to fish to whales, that depend on the kelp forest in one way or another as an integral part of their habitat.

Taxonomy

What are mollusks?

The mollusks or molluscs are the large and diverse phylum Mollusca, which includes a variety of familiar creatures well-known for their decorative shells or as seafood. These range from tiny snails, clams, and abalone to the octopus, cuttlefish and squid (which are considered the most intelligent invertebrates). There are some 70,000 described species within this phylum .

The giant squid, which until recently had not been observed alive in its adult form is the largest invertebrate although it is likely that the Colossal Squid is even larger. The scientific study of mollusks is called malacology.

Mollusks are triploblastic protostomes. The principal body cavity is a blood-filled hemocoel. It is unknown whether they have a true coelom (eucoelom); any coelomic cavities have been reduced to vestiges around the hearts, gonads, and metanephridia (kidney-like organs). The body is often divided into a head, with eyes or tentacles, a muscular foot and a visceral mass housing the organs.

Mollusks have a mantle, which is a fold of the outer skin lining the shell, and a muscular foot that is used for motion. Many mollusks have their mantle produce a calcium carbonate external shell and their gill extracts oxygen from the water and disposes waste. All species of the phylum Mollusca have a complete digestive tract that starts from the mouth to the anus. Many have a feeding structure, the radula, mostly composed of chitin. Radulae are diverse within the Mollusca, ranging from structures used to scrape algae off rocks, to the harpoon-like structures of cone snails. Cephalopods (squid, octopuses, cuttlefish) also possess a chitinous beak. Unlike the closely related annelids, mollusks lack body segmentation.

Development passes through one or two trochophore stages, one of which (the veliger) is unique to the group. These suggest a close relationship between the mollusks and various other protostomes, notably the Annelids.

Mollusk fossils are some of the best known and are found from the Cambrian onwards.

How do abalone eat?

Abalone are univalves and use a tongue-like organ called a radula to scrape algae like Kelp or Dulse into their mouths. Because they are not filter feeders and do not ingest free-floating algae, they are not affected by toxins associated with "Red Tides" like filter feeding bivalves (although they can be affected by the related elevated water temperatures).

Due to restrictions on hunting/diving for abalone, they are sometimes farmed (IE: in Cayucos, California) and these farm-raised abalone are fed wild ocean-grown seaweed that is harvested by boat from the same region.
