evolution of gastropods; 1.) bilaterally symmetric coiling is associated with bilaterally symmetric musculature of the foot mass; 2) tight coiling is associated with the contact of the head-foot mass and the mantle edge; 3) insertion of the foot muscle occurs in gastropods with an uncoiled ...
Snails and slugsare gastropods, belonging to the phylum Mollusca. They come in all different shapes, colors, and sizes, but they all share the common feature of having a shell and a foot which they use to move around. They feed using a tongue-like organcalled a radula. Their radula has ...
Most mollusks move with a muscular structure called a foot. The feet of different kinds of mollusks are adapted for different uses, like crawling, digging, or catching prey. ... These are mollusks like snails and slugs that have just one shell or no shell at all. Gastropods creep along on...
Like all gastropods, they havesmall, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sensory tentacles used primarily for the sense of smell—on their head, with a small eye at the base of each rhinophore. How big is the Blue Dragon? The blue dragon (Glau...
The Mollusca range from the gastropods, which includes snails and slugs, to the highly intelligent Cephalopods which include the octopus and squid.Answer and Explanation: The majority of Mollusca are typically filter-feeders or herbivorous grazers. The filter feeders eat by straining suspended food ...
Have foot attached to their heads Examples: squid, octopus, nautilus and cuttle fish Some have a radula, a tongue-like organ that protrudes from the mouth Many have protective “ink” Have a siphon that helps them move swiftly Gastropods Means “stomach footed” Muscular foot comes out of...
• A muscular foot used for movement • A visceral mass housing most of the internal organs • A mantle, which secretes the shell if present –The three major groups of molluscs are: • Gastropods, protected by a single, spiraled shell ...
Do sea slugs have teeth? Like all gastropods, they havesmall, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sensory tentacles used primarily for the sense of smell—on their head, with a small eye at the base of each rhinophore. ...
