The Aegean Sea had the highest number of species (875 species), followed by the Levantine Sea (859 species), the Sea of Marmara (635 species), and the Black Sea (163 species). In total, 133 species were alien molluscs that entered the Mediterranean Sea via different pathways. T...
Molluscs are found in marine, freshwater and terrestrial environments and in terms of numbers of species are second only to the arthropods. Body form varies widely within the phylum but the basic molluscan plan shows a head, often well developed and bearing sensory structures, a muscular foot, ...
Buttercups are popping up in the “more natural“ lawns of my neighborhood. We have a number of species buttercups in Missouri – this one isRanunculus harveyi(Harvey’s buttercup). In general, you can distinguish buttercups by their small, bright yellow flowers and bristle of anthers surroundin...
The greatest number of species was recorded in the Miedzanka - 17, less in the Duga - 14 and Maa Bystrzyca - 13. Density of molluscs varied between 1 and 78 ind./m2. Malacofauna found in the Duga, Miedzanka and Maa Bystrzyca was typical of small lowland rivers. 展开 关键词: ...
of living animal species[4]—far behind the arthropods' 1,113,000 but well ahead of chordates' 52,000.[7] It has been estimated that there are about 200,000 living species in total,[1][8] and 70,000 fossil species,[9] although the total number of mollusc species that ever existed,...

With probably around 200,000 extant species, Mollusca is the second-most speciose phylum after Hexapoda. However, what makes mollusks particularly interesting from an evolutionary perspective is not their richness in species as such, but rather the huge variety of body plan phenotypes exhibited by ...
Due to the great variety of colour patterns, the delimitation of different species could be hampered, especially if they are closely related and live in sympatry (e.g., Huang 1997; Blanco et al. 2014). This may explain the disparate estimates in the literature of the number of species of...
Variations in the Number of Intestinal Loops in Scaphopoda (Mollusca) The intestinal loops of two species of the genus Bathoxiphus (Entalinidae) and of Cadulus aberrans (Gadilidae) have been reconstructed from serial sect... G Steiner - 《Marine Ecology》 被引量: 24发表: 1994年 Aspects...
We found the presence of 11 species of trochidae at the study area. It was evident that some trochidae were common and while top shell Trochus niloticus seems to be rare. Vertical distribution among this group was uneven. The number of species decreases with increasing depth. Furthermore, high...
