Molecular/Barcoding Data

This page is an in-development cooperative work with SCOR WG157 (MetaZooGene,   The "MZG" plots and information tables below summarize known observations of this taxa (Tetrastemma) and locations associated with GenBank barcodes for this taxa or taxa group (red stars).   Additional information on this taxa is available at

Map Views:   [   World   |   Arctic   |   NATL   |   NPAC   |   Indian Ocean   |   Southern   ]

In the map above, light blue circles indicate where this taxa has been observed in COPEPOD or OBIS.
Red stars indicate locations where genus-level or species-level barcoding samples exist in GenBank or BOLD.

The table below shows the values plotted in the bargraph above.   Ocean columns indicate taxa has been observed in that ocean.
