Commen Water-Starwort

<em>Callitriche stagnalis</em>, commonly known as Common Water-Starwort, is an aquatic or semi-aquatic plant in the family Plantaginaceae. This species holds a Least Concern conservation status and is broadly distributed across Asia, Europe, North America, and Oceania, reflecting its wide ecological tolerance. It typically grows in diverse terrestrial and aquatic habitats, including ponds, streams, ditches, and wet meadows, often forming dense mats on the water surface or in shallow, slow-moving water. The leaves of Common Water-Starwort are typically small and arranged in rosettes at the water surface, allowing efficient access to light, while submerged leaves are often narrower and linear. This plant thrives in nutrient-rich, still or slowly flowing freshwater environments and can colonize temporarily flooded habitats. It provides important ecological services as habitat and food for aquatic invertebrates and small vertebrates. Biological traits of this species remain poorly documented in the scientific literature.

Tigr

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.
