<em>Salsola kali</em>, common saltwort or prickly glasswort, is an annual herb in the family Amaranthaceae, with a broad native distribution spanning coastal and inland saline habitats across Africa, Europe, and Asia, and widely introduced in North and South America where it has become an invasive species in many regions. The plant typically inhabits sandy beaches, coastal dunes, saline inland steppes, disturbed ground, roadsides, and agricultural margins. It is highly salt-tolerant, accumulating sodium in its tissues, a trait that historically made it a source of soda ash used in glassmaking, giving rise to common names such as glasswort. Common saltwort produces small, succulent, spine-tipped leaves and inconspicuous flowers, and when dry the plant breaks off at the base and tumbles in the wind, dispersing seeds widely — a behavior that has given rise to the iconic image of the tumbleweed in North American popular culture. The species is assessed as Least Concern on the IUCN Red List. It provides food for birds and invertebrates in coastal habitats. In North America it has expanded significantly into disturbed arid habitats, where it is considered invasive. Biological traits such as average lifespan, body measurements, and dietary data remain poorly documented in standardized databases.

<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.
