More than 40 different species of freshwater fish have been identified in New Zealand’s waterways. Around three-quarters of these secretive and largely nocturnal natives are already endangered, which is a troublingly high number compared to other countries. Some of the issues our freshwater fish face include barriers in migration, destruction of habitat and the introduction of predators such as trout.
Many of New Zealand’s freshwater fish species have had to evolve unique attributes in order to live in our varied habitats. The lowland longjaw galaxias is so named for its distinctive upturned lower jaw, the redfin bully has taught itself to climb, the longfin eel can live for up to 100 years, the lamprey is commonly known as a “vampire parasite” and the torrentfish has a unique zebra-style camouflage.
From deep ice-cold lakes to fast moving raging rapids, the vast range of species found in New Zealand’s waterways are celebrated with these beautifully illustrated stamps. The diversity of New Zealand’s aquatic life is clearly apparent when these stamps are viewed side by side.
