Chaetoceros coarctatus is a marine, unicellular species of planktonic diatom in the genus Chaetoceros, first described by Lauder in January 1864 using samples from the Hong Kong harbor.[1] Like many diatoms, it is preyed upon by ctenophores.[2][3] During warming periods of the Mediterranean Sea, this non-native species, first introduced through the Suez Canal, expands its range.[4] Cell chains showcase pairs of posterior and anterior terminal setae, as well as intercalary setae, for anti-predatory mechanical protection and floating benefits.[5] These silica appendages have spines, curved tips, and are longer those on other members of the Chaetoceros genus for higher survival benefits.[6]
