Common Ivy

<em>Hedera helix</em>, commonly known as common ivy or English ivy, is a woody evergreen climber and groundcover in the family Araliaceae. It is classified as Least Concern on the IUCN Red List, with a very wide global distribution across the Palearctic realm and beyond, encompassing temperate and Mediterranean habitats. The species is native to Europe and western Asia and has been widely introduced elsewhere. It typically grows in woodlands, hedgerows, cliffs, walls, and urban green spaces, tolerating deep shade and a wide range of soil conditions. Common ivy provides important ecological services, offering shelter and late-season nectar and fruit resources for wildlife. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

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.
