common nut clam

<em>Nucula nucleus</em>, the common nut clam, is a small marine bivalve mollusk in the family Nuculidae, among the most primitive living bivalves in terms of evolutionary lineage. This deposit-feeding species typically burrows into soft sediments — muddy and sandy substrates — in coastal and subtidal marine environments. <em>Nucula nucleus</em> uses its elongated palp proboscides to sort organic particles and detritus from sediment, making it a key functional contributor to benthic nutrient cycling. Its geographic range spans European Atlantic and Mediterranean coasts, with documented occurrences in Belgium, Denmark, Norway, and Sweden, typically in sheltered bays, estuaries, and sublittoral soft-bottom habitats. The species is currently assessed as Least Concern by the IUCN. Biological traits such as lifespan, body size, and diet remain poorly documented at a population level for this species in formal assessments, though it is known as a selective deposit feeder. The common nut clam plays an important role in benthic community structure and sediment processing, and serves as prey for demersal fish, sea stars, and other bottom-dwelling predators across its European range.

Harimau

The largest wild cat on Earth, tigers can exceed 300 kg and inhabit forests from the Russian Far East to Southeast Asia. Solitary ambush predators with distinctive orange and black striped coats that provide camouflage in dappled light. Critically endangered, with fewer than 4,000 remaining in the wild due to poaching and deforestation.
