common intertidal amphipod

<em>Gammarus locusta</em>, commonly known as the common intertidal amphipod, is a crustacean in the family Gammaridae. Its conservation status has not been formally evaluated by the IUCN. The species is recorded from Denmark, Norway, Portugal, and Sweden, indicating a distribution along the northeastern Atlantic coast of Europe. It typically inhabits intertidal and shallow subtidal marine and estuarine environments, where it is found among algae, under rocks, and in sediments. Gammarus amphipods are ecologically important as detritivores and as prey for shorebirds, fish, and other invertebrates in coastal food webs. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

Gray/Purple Heron

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
