Apr 23, 2019 Unexpected observation of freshwater invertebrate Daphnia magna in temporary rock pools on a small island off the Norwegian Atlantic coast 


The Spiny Water Flea (Bythotrephes longimanus) is native to the freshwater lakes of Europe and Asia. It made its way to the Great Lakes by 1984 and probably reached our lakes not long after. Like Daphnia, which is also a type of water flea, Spiny Water Fleas can either reproduce asexually, to achieve very dense populations, or sexually, to produce hardy resting eggs.

The genus “Daphnia” is a group of aquatic organisms which are commonly known as “water fleas” and can range in body length from 0.2–8.0 mm with the exception of Leptodora, which measures up to 18 mm. Daphnia are commonly found in freshwater. They live in almost every nutrient-rich (eutrophic) body of water. Daphnia are filter feeders that direct small suspended particles into their mouth by a water current produced by their leaf-like legs (Figure 1). Daphnia 's common name of 'water flea' comes from its jump-like movement, which results from the beat of the large antennae used for swimming (Figure 1).

Some types of Daphnia can be seen Non-steroid anti-inflammatory drugs (NSAIDs) have been frequently detected in aquatic ecosystem and posed a huge risk to non-target organisms. The aim of this study was to evaluate the toxic effects of three typical NSAIDs, diclofenac (DFC), acetaminophen (APAP) and ibuprofen (IBP), toward the water flea Daphnia magna.

Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas. Like Daphnia, which is also a type of water flea, Spiny Water Fleas can either reproduce asexually, to achieve very dense populations, or sexually, to produce hardy resting eggs. Unfortunately, Daphnia are a favorite prey of the larger B. longimanus. The best known genus is Daphnia, ubiquitous in ponds and streams in Europe and North America.

Daphnia are small, planktonic crustaceans, which are commonly called water fleas because of their swimming style. They live in various aquatic environments ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Daphnia pulex was the first crustacean to have its genome sequenced. 2019-05-01 · The water flea Daphnia magna is a small planktonic cladoceran and is the largest in the Daphnia genus, with the females growing up to 5 mm in size (Benzie, 2005). D. magna is commonly found in the northern hemisphere and can be found in fresh and brackish water bodies including lakes, rivers, and temporary pools (Ebert, 2005; Weber, 1991).

The name water flea is a nickname; it is also called a daphnia. These tiny critters are part of the freshwater plankton.
