the three features defining modern molluscs are a mantle (used for breathing) the presence of a radula (for feeding) and the structure of the nervous system
Mollusca is one of the most diverse hb groups of animals on the planet It includes such familiar organisms as snails, octopuses, squid, clams, scallops, oysters, and chitons. Molluscs are a clade of organisms that all have soft bodies which typically have a head and a foot region. Often their bodies are covered by a hard exoskeleton, as in the shells of snails and clams or the plates of chitons.molluscs are extremely important members of many ecological communities. They range in distribution from terrestrial mountain tops to the hot vents and cold seeps of the deep sea.
1. Clams and mussels can live in the sea and the river. 2. Octopuses have amazing defenses. They can change their coloring to blend in with their surroundings. 3. Mollusks are the second largest phylum in the animal kingdom after the phylum Arthropoda
Mollusca can be eaten, specifically clams, snails, and oysters. Many of freshwater and terrestrial Mollusca are going extinct because of agricultural concerns and invasive species. An unhatched baby octopus can squirt ink.
1. There are around 50,000 species of mollusca including the five main ones, 2. The giant squid is the largest creature without a backbone, which is a part of the mollusca family 3. Worlds largest snail is the Australian Trumpet.
around 85,000 species of molluscs are recognized/discovered

Mollusk means soft! This is why mollusca, which do not have skeletons or exoskeleton, are derive their name from Mollusk
ReplyDeleteMany mollusks live in the sea! For instance, the Giant Clam, Cockle, Giant Squid, Nautilidae, and blue-ringed octopus all live in the sea.
ReplyDeleteThe Giant Squid is huge! In fact, some can grow up to 55 feet long. However, the majority of Octopi are about 33 feet long.
ReplyDeleteMoullusks' apperances are very diverse. They include squids, octopi, snails and slugs.
ReplyDeleteMost Moullucs have a rasping tongue called a radula with tiny teeth. They scrape plants and animals off rocks or tear food into chunks.
ReplyDeleteMoulluscs occur in almost every habitat on Earth, and a lot of them are in water.
