Peru Tambopata River

 

Peru

The location of this site where I took some interesting samples is the Cocococha Lagoon, an old meander of the Tambopata River, where a giant otter family occurs. My samples came from waterplants, covered with detritus. The exact location is: 12º 49′ 05.72” S, 69º 15′ 42.74” W (see arrow). The site is located about 30 km south south west of Puerto Maldanado.

  • Arcella costata
  • Arcella rotundata
  • Centropyxis ecornis
