• Achelous spinimanus

  Blotched Swimming Crab

  Achelous spinimanus is a swimming crab native to the Western Atlantic, ranging from the USA to Brazil. It inhabits coastal marine environments from shallow waters to 90 m depth, with distinct depth preferences between life stages: juveniles occur at 5–35 m while adults are most abundant at 25 m and range to 40 m. The species exhibits continuous year-round reproduction with ovigerous females present in all seasons, and shows seasonal migration patterns in response to water temperature and salinity changes. It is an emerging fishery resource in Brazil, where it has become a target species following declines in more traditional catches.

• Tanais dulongii

  Tanais dulongii is a small benthic tanaid crustacean with a strictly benthic life cycle and low dispersal capacity. It is widely distributed across temperate coastal waters of the Atlantic, Mediterranean, and Indian Oceans. Populations exhibit continuous reproduction with year-round presence of reproductive individuals and juveniles, and show plasticity in life history traits in response to environmental quality.
