Their bodies are elongated and compressed with greatly depressed heads. They have long air sac that serve as lungs that extends from the gill chamber. The dorsal fin is short and has no spine. The pectoral fins have an associated venom gland and as a result the fish is considered dangerous.[1] They are oviparous; distinct pairing is possible.

Species

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

gollark: Don't most developed countries have weirdly skewed demographics like that now?
gollark: Which some people probably like.
gollark: It is also claimed that basically every weird subculture exists there to some extent.
gollark: Apparently there are also some bad incentive structures, because property owners can go "no, you cannot build denser things here", and they're incentivized to so they can sell their stuff for more.
gollark: So just make it denser and have better transport.
