Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Denmark, Iceland, Norway, and Sweden.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

common European cockle

<em>Cerastoderma edule</em>, the common European cockle, is an intertidal bivalve mollusc in the family Cardiidae, classified as Least Concern by the IUCN Red List. The species is native to European coastal waters and has been documented in Belgium, Denmark, Iceland, Norway, and Sweden, where it typically inhabits sandy and muddy intertidal and shallow subtidal sediments in estuaries, bays, and open coastlines. <em>Cerastoderma edule</em> is a filter feeder, drawing in seawater through its siphons to extract phytoplankton, bacteria, and organic particles. It is recognized by its distinctive ribbed, cream-colored shell with radiating ridges and concentric growth lines. Cockles are a keystone species in many European coastal ecosystems, providing an important food source for shorebirds such as oystercatchers and knots, predatory fish, crabs, and starfish. The species also supports one of the most commercially significant shellfish fisheries in Europe, with large-scale harvesting operations in the UK, the Netherlands, and Ireland. Dense cockle beds stabilize intertidal sediments and contribute to benthic productivity. Population dynamics are closely linked to sea surface temperature, salinity, and sediment availability, making this species a useful indicator of estuarine ecosystem health. Biological traits of this species remain poorly documented in the scientific literature.
