A species of red algae has been discovered near Bahamas at a depth of more than 260 m. This unusual feat is possible because this alga:

1. lacks pigmentation and functions heterotrophically as parasite on other plants
2. has significant amount of phycoerythrin in addition to chlorophyll a and d
3. unlike other red algae has flagellated gametes
4. it has large number of root like rhizoids enabling it to attach to a deep substratum
