Sri Lanka’s extraordinary biodiversity — spanning everything from ants in home gardens to blue whales in its surrounding oceans — took centre stage at Thursday’s public lecture that highlighted the ...

Researchers at the University of Bristol have traced the genetic changes that allowed animals to colonize land not once but ...

Some phenotypes, such as traits and structures, evolve only once, and phenotypes that evolve repeatedly are original for a given time period. Geerat Vermeij and Tracy Thomson analyzed the fossil ...

Mollusks have produced many evolutionary innovations since they first appeared 540 million years ago, including spiral shells and a toothed tongue. A new study shows that about half of these ...

All insects belong to the phylum Arthropoda. But unlike other arthropods—like lobsters, spiders, or millipedes—insects have three pairs of jointed legs, segmented bodies, an exoskeleton, one pair of ...

The Dumbo octopus is an elusive cephalopod that gets its name from its large ear-like fins, which resemble those of the lovable Disney elephant. But there's still lots we don't know about these ...

Phylogenies are essential for organizing knowledge on biological diversity, structuring classifications, and providing insights into evolutionary events. Worldwide phylogenetic studies on mollusks ...

The classification of a production area determines the treatment required before Live Bivalve Molluscs (shellfish) may be marketed for human consumption. Shellfish production and relay areas are ...

Byssus is an extremely fine, rare, and valuable fabric of animal origin. It is a sort of natural silk with golden and sparkling reflections that is obtained from the filaments secreted by a large ...
