Seashells and mollusks explored by The Mini Page
This week The Mini Page previews seashells and their mollusk relatives. It explains how shells form from minerals secreted by a mantle, how growth rings indicate age, why colors vary with diet and growth rate, and differences between single shelled snails and two shelled bivalves like clams and oysters.
Shellfish life and respiration in tidal habitats
Shellfish use a strawlike siphon to pull water across gills for breathing and feeding. Some host algae that make energy from sunlight, sharing it with the shellfish. Bivalves open to feed and breathe, close when threatened or during low tide to avoid drying out, then reopen when water returns.
Collecting shells safety and ecological note
Do not remove shells that harbor living animals as all living things matter to the environment. Some shellfish can sting and cone shells possess a venomous harpoon that paralyzes prey. People may have serious reactions to stings, so handle with care.

Ocean heat drives 22 percent drop in marine microbes
A satellite study of 21 years of data shows by April 2023 a 22 percent decline in phytoplankton algae and bacteria, with nearly three quarters of the global ocean surface affected. One scientist warns the results are very concerning for marine ecosystems, though recovery is possible in time.
Marine life feature highlights ocean creatures and conservation
A local newspaper roundup explores marine life, detailing coral ecosystems, whale species, and coastal habitats. It highlights conservation efforts, research findings, and the roles of scientists and volunteers in protecting oceans.
