Taxonomy

Within the tribe Otothyrini, Pseudotothyris has a sister group relationship with Otothyris. In turn, Otothyropsis has a sister group relationship with the clade Otothyris plus Pseudotothyris.[1] These three genera and Schizolecis share unique specializations of the cranium associated with an enlarged swimbladder capsule. The degree of development of the swimbladder capsule in these genera was not found in any other member of the Otothyrini.[1]

Species

There are currently 3 recognized species in this genus:[2]

gollark: No. You need something like GMP for bignums, but C has no operator overloading due to C bad.
gollark: Technically yes, practically not really I think; each connection has a bunch of state associated with it; the actual status of the TCP stream, and the random bytes the websocket data is XORed with (for entirely accursed reasons).
gollark: This is premature optimisation.
gollark: It doesn't actually matter unless you're writing some kind of hyperoptimized algorithm, which you aren't.
gollark: You can just use example.com, it has no SSL redirection.
