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.

Nitzschia intermedia는 Bacillariaceae과에 속하는 우상형 규조류로, 담수에서 약간 기수성인 서식지에 분포하며 저서 및 부유생물 생태적 지위를 모두 점한다. 용골 봉선과 세밀한 횡중심 선조를 가진 길쭉한 껍데기는 대형 속 Nitzschia의 전형적 특징이다. 수생 모니터링 프로그램에서 중간 수준의 유기물 및 영양소 농화 지표로 활용된다.
