First Detection of Infecting a Wild Population of Blue Mussels in the United Kingdom.

In the last decade, declines in the population of wild blue mussels in the Tamar estuary (United Kingdom) have been noted. In archived samples collected from 2013 to 2019, between 7% (in 2013) and 18% (in 2019) showed large granulocytoma and haemocytic infiltration in the interstitial tissue of the digestive gland. Four samples were selected for gene Nanopore sequencing.

The Common Sunstar -A Neurotoxic Starfish.

Saxitoxins (STXs) are a family of potent neurotoxins produced naturally by certain species of phytoplankton and cyanobacteria which are extremely toxic to mammalian nervous systems. The accumulation of STXs in bivalve molluscs can significantly impact animal and human health. Recent work conducted in the North Sea highlighted the widespread presence of various saxitoxins in a range of benthic organisms, with the common sunstar () demonstrating high concentrations of saxitoxins.
