They typically live in fast-flowing highland streams, and are small fish, no more than 15 cm (5.9 in) in length. Some species are sexually dimorphic, with the male possessing a rosette on the gill covers that is absent in the females. Other species are neotenic, retaining larval features into adulthood.[1]
Classification
About 30 species are in four genera:[2]
gollark: No, what I mean is, are there easy to find but hard to verify problems?
gollark: No, other way round.
gollark: There are probably problems like that maybe. I think mostly for cryptography.
gollark: Well, you could set up your tax form such that it's easy for you to make and hard for them to verify.
gollark: > Well, on the other hand, many problems in nature are so computationally brutally hard that we can never truly hope to compute them, which prevents us from building a true virtual universe. I would say that's something positive.How is this a *good* thing?
