Common iceplant

<em>Mesembryanthemum crystallinum</em>, commonly known as the common iceplant, is a succulent annual or short-lived perennial in the family Aizoaceae. Its conservation status has not been formally evaluated by the IUCN. The species is distributed across Asia, Europe, North America, and South America, with a wide global footprint that includes both native populations and naturalized occurrences. It typically inhabits coastal and arid environments, saline soils, disturbed ground, and rocky slopes where competition from other vegetation is limited. The plant is named for the glistening bladder-like cells on its surface that resemble ice crystals. 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.
