Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

common guitarfish

The common guitarfish, <em>Rhinobatos rhinobatos</em>, is a cartilaginous fish belonging to the order Rhinopristiformes, family Rhinobatidae. It is a member of the guitarfish group, characterized by a flattened body with a distinct guitar-like silhouette formed by the fusion of the head, pectoral fins, and trunk. <em>Rhinobatos rhinobatos</em> is assessed as Critically Endangered on the IUCN Red List, representing severe conservation concern and indicating that this species faces an extremely high risk of extinction in the wild. Pressures such as overfishing and bycatch are commonly implicated in the decline of guitarfish species globally. Detailed habitat, range, and country distribution data are not available for this species in current records. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
