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.

Pyrenula nitida는 서유럽 습한 대서양 삼림의 오래된 활엽수 매끄러운 수피에 매끄럽고 광택 있는 올리브 녹색에서 갈색 엽상체와 내포된 플라스크형 병각을 형성하는 수피생 각피 지의류이다. 서유럽에서 지속성 오래된 삼림의 대표 지표종으로 여겨진다. 고목 및 오래된 삼림 서식지의 손실로 심각하게 위협받는 멸종위기 지의류이다.
