2 climbers atop Table Mountain admire the 2 currents and the 2 ecosystems of the 2 different shores of the Cape Peninsula. That’s a lot of 2s.

As described by the plaque in the photo above:

There are few places on earth where a narrow finger of land, like this peninsula, separates waters as different in temperature and character as the life they support. Just off this coast the cold, wind-driven and nutrient-rich Benguela Current from the Antarctic mingles with the warm Aguilhas Stream descending the east coast from the tropics–the invisible junction of two rich and unique marine provinces.

Of the 2008 identified vertebrate and invertebrate marine species found off Southern Africa, 33% occur along the Cape Peninsula. Remarkable when one considers that the peninsula represents just 3% of the entire coastline from Namibia to Mozambique.
