In January 2016 I visited the Northern Cape for the first
time. One of the places I visited was Goegap near Springbok, spending
about three days in the area. I was impressed by the landscapes and
biodiversity of the region. I was given another opportunity to visit Goegap during the last week of September 2017, this time for a week. Our objective
was to help wildlife film makers, Henk Ekermans and Barend van der Watt, find
and shoot some of the smaller animals of this biodiversity rich ecosystem.

Hot arid gravel plain. At night these come alive with geckos and scorpions. |

Many-horned Adder (Bitis cornuta) we were lucky enough to see. A definite reptilian highlight of the trip. |
Some colour. Western Sandveld Lizard (Nucras tessellata) found foraging among the plants. |
We were lucky enough to have access to many inaccessible
areas of the reserve and given permission to travel freely even at night. This
allowed us, despite the cold dry weather, to find many interesting reptiles,
arachnids and centipedes while being immersed in dream like landscapes. A big
attraction to the area this time of year is the Namaqualand flowering period.
Unfortunately the rains did not arrive this year so the flowers were few and
far between, still we saw some amazing plants.
Interesting quartz outcrop. |

We were quite lucky with our reptiles and wracked up a nice
species tally with a few we had never seen before. Our totals in the end were
32 reptiles; with seven snakes, 23 lizards, 2 tortoises (shells only). The list

Scorpions
Besides the reptiles, which were good, the Northern Cape region is also an arachnid hotspot. Anyone that knows me knows I love scorps and here are a few of the amazing scorpions and centipeds we found along the way.
Uroplectes gracilor
Parabuthus capensis
Parbuthus shlechteri
Parabuthus granulatus
Opistophthalmus granifrons
Opistophthalmus peringueyi
Opistophthalmus pallipes

A nightmare to identify! But we try: Ethmostigmus sp and Scolonependera mortisans
The most beautiful Scolonependera mortisans I have seen. |
A large and scary Ethmostigmus |
Harpactira namaquensis. A beautiful Baboon Spider. |
Overall we had an amazing week, we saw and experienced so
much biodiversity. Working and living close to another river system (Limpopo)
on the opposite side of the continent, experiencing the !Garib system and all
it’s different animals, plants, climatic conditions is such a privilege. Many
thanks to Barend and Henk for the opportunity and making our stay extra
comfortable.
Louse Fly biting! |
