Habitat & Geographic Range

Barn Owl

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Widely distributed across Africa (Seychelles), Europe (6 countries), North America (United States), and South America (Colombia, Ecuador, Venezuela). Population trends indicate a declining trajectory in parts of its range.

common bubble snail

Habitat

Typically found in terrestrial and aquatic habitats including forests and freshwater.

Range

Distributed across Denmark, Norway, Portugal, and Sweden.

Barn Owl

The most widespread owl species on Earth, barn owls are found on every continent except Antarctica and in almost every habitat type from tropical forests to temperate farmland. Characterized by their heart-shaped facial disc that funnels sound to asymmetrically placed ears, enabling them to locate prey in total darkness by sound alone. They swallow prey whole and regurgitate compressed pellets of indigestible bone and fur, making them valuable rodent control agents for agriculture.

common bubble snail

The common bubble snail (<em>Akera bullata</em>) is a marine gastropod mollusc found in the coastal waters of Denmark, Norway, Portugal, and Sweden. This species typically inhabits terrestrial and aquatic environments including forests and freshwater-adjacent marine areas, often occurring in shallow subtidal and intertidal zones of temperate European seas. It is classified as Least Concern on the IUCN Red List. As a member of the family Akeridae, the common bubble snail is characterized by its thin, fragile shell and its ability to swim briefly by flapping its large, wing-like parapodia. The species often forages on algae and detritus in sandy and muddy seafloor habitats, particularly in sheltered bays and estuaries. The common bubble snail typically aggregates in large numbers during the spawning season, producing gelatinous egg masses. Biological traits of this species remain poorly documented in the scientific literature.
