Distribution and habitat

The genus Sturisomatichthys is distributed in the northwestern part of South America, on the Pacific and Atlantic slopes of the Andes. The species appear to occupy the same ecological niche as those in Sturisoma.[2]

Description

Sexual dimorphism and reproductive biology of Sturisomatichthys similar to Sturisoma. Sturisomatichthys is distinguished from Sturisoma primarily by the absence of a rostrum. Only one species, S. citurensis, from Panama, seems to be significantly different from all congeneric species in having an abdominal plate cover consisting of small platelets without any particular organization. Other species may represent a species complex with a short snout as in the genus Farlowella with reference to the representatives of the F. curtirostra group. The weakness of this diagnostic feature could lead to the synonymy of Sturisomatichthys with Sturisoma.[2] Sturisomatichthys species grow to about 18–25 centimetres (7.1–9.8 inches) in length.[1]

gollark: The trouble, although in general I think this is good, is that you can't really have some code run without it being possible for people to inspect it in some way.
gollark: It could be trivially decrypted with the public key which ships with all potatOS builds, which is basically the point.
gollark: Actual "cryptographic obfuscation" would be, I don't know, encrypting stuff with the potatOS signing key™?
gollark: It's MILDLY obfuscated.
gollark: No, although potatOS did used compressed base64ed bytecode for one thing.
