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 |
