Students will identify the external anatomy of a clam and describe the function of important external features. They will be able to identify the major internal organs of a clam and their functions related to swimming, digestion, and respiration. Additionally, students will demonstrate dissection skills (for live dissections). Using a dissection guide or a virtual dissection on the computer, the students will participate in a dissection of a clam (preserved or fresh).
What is the phylum of mollusks?
Mollusks are animals belonging to the phylum Mollusca. There are around 93,000 recognized extant species, making it the largest marine phylum with about 23% of all named marine organisms. Representatives of the phylum live in a huge range of habitats including marine, freshwater, and terrestrial environments. Molluscs are a highly diverse group, in size, in anatomical structure, in behaviour and in habitat. The phylum is typically divided into nine or ten taxonomic classes, of which two are entirely extinct. Cephalopod molluscs such as squid, cuttlefish and octopus are among the most neurologically advanced of all invertebrates. Either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods (snails and slugs) are by far the most numerous molluscs in terms of classified species, and account for 80% of the total number of classified molluskan species.
