Clams, snails, slugs, mussels, oysters, and clams are all considered to be mollusks. Squid and octopi are also mollusks but we put them on a different page because they are very cool and actually somewhat intelligent. Clams are not known for their intelligence.

Pearls come from the oyster, an invertebrate (mollusk). You might tell students that oyster shells are also used in natural calcium supplements. Shells such as a conch as well as those that would be used in a necklace come from shelled invertebrates, mollusks.

Slugs and snails are invertebrates (animals without backbones) with soft bodies that they drag around on a single, muscly “foot”. Snails can hide inside their shells to escape from danger. Slugs and snails belong to a huge family of animals called molluscs.

Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape….

Scallops are molluscs like mussels, oysters, and clams. They’re unique in that they’re the only free-swimming bivalve: Scallops use their large central muscle (called the adductor) to clasp their shells shut, shooting water out one end and propelling themselves forward in the other direction.

Scallops are rich in magnesium, B12, zinc, selenium and loads of protein. Oysters: They’re the most nutrient dense, most expensive and taste pretty dang good with lemon juice and hot sauce. Oysters are the single greatest source of dietary zinc, which the body uses to produce testosterone.

Marine animals in the shellfish category include crustaceans and mollusks, such as shrimp, crab, lobster, squid, oysters, scallops and others. Some people with shellfish allergy react to all shellfish; others react to only certain kinds.

Do oysters have eyes? Yes, these marine creatures have eyes all over their bodies that allow them to escape their predators.

Despite the fact that it sounds incredibly gross and cruel, it’s actually better for you to eat them in this way. That’s because dead oysters which are eaten raw can contain bacteria that is harmful to humans and can make us ill – with symptoms including a fever, vomiting and diarrhoea.

Shellfish Toxins Bivalve molluscan shellfish like clams and oysters obtain food by pumping water through their system and filtering out small organisms. If large numbers of the toxic algae are present in the water, then the shellfish can accumulate high levels of the toxin.

While this mineral is important for health, consuming too much can be harmful. Though zinc toxicity is most often associated with supplements, eating too many oysters too frequently can lead to negative health effects, such as reduced levels of the minerals copper and iron that zinc competes with for absorption.

Why are canned oysters banned in California? Canned oysters are for sale in California. Under California Proposition 65, lead and cadmium are listed as chemicals known to cause birth defects or other reproductive harm.

Rule of thumb is at least 4,000 years old. Foodie tradition dictates only eating wild oysters in months with the letter “r” – from September to April – to avoid watery shellfish, or worse, a nasty bout of food poisoning. Now, a new study suggests people have been following this practice for at least 4,000 years.

The ‘R’ rule stated that oysters should only be eaten in months than contain the letter ‘R’. So that means you should only be enjoying oysters in September, October, November, December, January, March and April.
