Coastal Bastard Toad-flax

Thesium maritimum, the coastal bastard toad-flax, is a semi-parasitic herbaceous plant in the family Santalaceae native to coastal sand dunes, calcareous grassland, and scrubland along the northern Mediterranean coast of Europe, extending through the Iberian Peninsula and into parts of southwestern France. Like other members of the genus Thesium, it is a hemiparasite, maintaining chlorophyll and photosynthesizing while simultaneously tapping the root systems of neighboring grasses and herbs to extract water and nutrients through haustorial connections. The species produces small, narrow leaves and inconspicuous white to cream flowers typical of the family, lacking showy petals and relying on insect visitors for pollination. Thesium maritimum is classified as Vulnerable by the IUCN, reflecting significant population declines associated with loss and degradation of its specialized coastal habitat through tourist infrastructure development, coastal stabilization, invasive species encroachment, and sand dune fixation. Mediterranean coastal sand dune systems across Europe have been extensively modified, and the open, dynamic habitats required by this specialist species have contracted substantially over recent decades. Conservation measures include dune restoration, reduction of vehicle traffic on coastal habitats, and control of invasive species that fix and stabilize natural shifting sands.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
