Collared Treepie

The Collared Treepie, known scientifically as <em>Dendrocitta frontalis</em>, is a corvid belonging to the family Corvidae. <em>Dendrocitta frontalis</em> is a member of the treepie group — arboreal corvids found in Asian forests — and is characterised by its long graduated tail, colourful plumage, and bold behaviour typical of the crow family. The species typically inhabits dense subtropical and tropical montane forest environments, where it forages in the canopy and mid-storey for fruits, insects, eggs, and other food items. It is reported to occur in Norway according to available range data. Treepies are generally noisy and active birds, moving through forest with rapid hops and flights. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Treepie is currently assessed as Least Concern on the IUCN Red List.

common sea hare

<em>Aplysia punctata</em>, the common sea hare, is a large opisthobranch sea slug in the family Aplysiidae, order Aplysiida, found in the northeastern Atlantic Ocean and Mediterranean Sea, with confirmed records from Denmark, Norway, Portugal, and Sweden. This species typically inhabits shallow subtidal and intertidal zones with abundant macroalgae, feeding primarily on red and green algae — a diet that influences the color of the defensive purple ink it secretes when threatened. <em>Aplysia punctata</em> is a simultaneous hermaphrodite, capable of acting as both male and female during mating, and often forms mating chains involving multiple individuals. It can reach considerable size among European opisthobranch species, though body dimensions vary considerably with age and feeding conditions. The species is classified as Least Concern by the IUCN, reflecting stable populations across its coastal range. Biological traits for this species remain poorly documented in the scientific literature, including precise average data on lifespan, body length, weight, and detailed seasonal dietary patterns, though its general herbivorous feeding on macroalgae is well established.
