Description: Armored, laterally flattened, ovalshaped cells with small flat or rounded epitheca. Hypotheca is usually about of the cell length.

Apparently no recent synonym, other than Dinophysis diegensis Kofoid 1907. This latter species is morphologically different but several authors report it as 'small cells' in the life cycle of D. caudata and D. tripos (Reguera et al. 1990, 1995; Moita& Sampayo 1993; Reguera& GonzalezGil 2001; Reguera et al.

Reproduction: D. tripos reproduces asexually by binary fission. Moita and Sampayo (1993) speculate that sexual reproduction, with sexual dimorphism, is part of the life cycle for this species. Ecology: Dinophysis tripos is a planktonic species commonly found in neritic, estuarine and oceanic waters (Steidinger& Tangen 1996).

No blooms for this According to body measures, the potential predators of Dinophysis spp. (e. g.mainly Dinophysis tripos which was the dominant species of this genus in samples) in the m size fraction and their abundances, are presented in Table 2. They belong to dinoflagellates, aloricate ciliates, and tintinnids, all microzooplanktonic groups. Dinophysis thecae are divided into halves by a sagittal fission suture. There are five types of thecae ornamentation in this genus, and those are a useful character for species identification.

Dinophysis mainly divide by binary fission. Dinophysis chloroplasts are usually rodshaped or granular and yellow or brown colored. Dinophysis tripos can be confused with D. caudata; some cells of D. caudata, bearing a short hypothecal process, can superficially resemble D. tripos. However, D. tripos can When D. tripos was the only species in Dinophysis blooms (4590 pg PTX2cell), no toxins detected in shellfish.

This could be explained because PTX2 is very quickly converted into non toxic PTX2 SA by mussels. Dinophysis caudata is one of several species in the genus that are mixotrophic (both predatory and photosynthetic), with a number of chloroplasts that are orangered to yellowgreen (Figures 1, 3, 6). 10: 35: 21 Wenche Eikrem Added media: Dinophysis tripos2. jpg Nordic Microalgae is developed and operated by the Swedish Meterological and Hydrological Institute (SMHI) with funding from the Swedish LifeWatch project.
