The proposals include awarding a new status or an amended status with a view to protecting whales, elephants, tortoises, mahogany, sharks and icefishes
They then compared these phylogenies with those of other groups of fishes (Lake Victoria cichlids and icefishes
) in which "species flocks" occur.
1990), and for a group of icefishes (within Notothenioidei).
For sequence data (i.e., for the rockfishes, cichlids, and icefishes), ML trees with contemporaneous tips were generated.
Temporal Speciation Patterns in Cichlids and Icefishes. - One striking contrast between the rockfishes (current study) and the Lake Victoria cichlids (Meyer et al.
Cichlids and Icefishes. - In contrast to the rockfishes, the sharp burst of speciation in the cichlid fishes of Lake Victoria occurred in the very recent past.
Some Antarctic fishes, the icefishes (Channichtyidae) have even lost their respiratory pigments (Ruud, 1954).
At the low temperatures of Antarctica icefishes rely exclusively on the transport of oxygen that is physically dissolved in the blood (see Introduction).
