Chaetoceros coarctatus is a marine,
unicellularspecies of
planktonicdiatom in the
genusChaetoceros, 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]
