FAQ
Frequently Asked Questions
Some species produce toxins that can cause harmful algal blooms (red tides), poisoning fish and shellfish, which in turn can affect human health. Not all species are toxic.
Common pronunciations are /ˌdʒɪmnəˈdɪniəm/ (US) or /ˌdʒɪmnəʊˈdɪnɪəm/ (UK). The emphasis is typically on the 'din' syllable.
Individual cells are microscopic. However, during a dense bloom, the water may appear discolored (red, brown, or green), making the population visible en masse.
The key distinction is that Gymnodinium lacks a rigid cell wall of cellulose plates (a theca), making it a 'naked' or 'unarmoured' dinoflagellate. Related genera like Alexandrium have such armour.
