Harmful effect G. cheloniae produced the putative maitotoxin-3 analogue, MTX-3, but neither maitotoxin
or monitored ciguatoxin. Extracts of G. cheloniae were shown to be highly toxic to mice by intraperitoneal (i.p.) injection, although they were less toxic by gavage. It is possible that this species produces toxins other than putative MTX-3. See Smith et al. (2016). [details]

Description The photosynthetic cells of G. cheloniae are anteroposteriorly compressed, with mean depth (ventral to dorsal distance) measuring 59.5 ± 12.2 μm, width (transdiameter) 62.9 ± 9.0 μm, and length (apical to antapical axis measured in either ventral or dorsal view) 32.6 ± 3.7 μm. The cells are rugose, although exceptions of individual smooth cells (possibly recently divided) were observed by SEM. The apical pore is almost centrally placed (not markedly displaced) and the 2' plate is hatchet shaped andaverages 16.2 μm (width) by 29.3 μm (length). The round thecal pores are approximately 0.3 μm in diameter. There are two flagella. Plate formula Po, 3' , 6” or 7”, 6C?, 6 or 7S, 5'"", 1p and 2”"". In antapical view, Plate 1p averages 16.2 μm (width) by 30.0 μm (length). It is slightly broader at the ventral end, which is pointed. The cingulum displays a pronounced list. [details]

or monitored ciguatoxin. Extracts of G. cheloniae were shown to be highly toxic to mice by intraperitoneal (i.p.) injection, although they were less toxic by gavage. It is possible that this species produces toxins other than putative MTX-3. See Smith et al. (2016). [details]
