Pao palembangensis

The humpback puffer Pao palembangensis[2] or Tetraodon palembangensis, is a species of freshwater pufferfish native to Thailand, Laos, Malaysia and Indonesia in Southeast Asia. Living in alkalescent, warm (24–28°), and slow-flowing rivers. It grows to a length of 19.4 centimetres (7.6 in) SL, with both sexes having a similar body size, but the male having a much larger rear hump.[3] The humpback puffer is a popular ornamental fish because of its beautiful skin colouration and pattern. As a pufferfish its body contains the neurotoxin tetrodotoxin (TTX),[4] and it can swell up to three times its normal size as a defence mechanism when threatened.[5] Having a small genome size (362Mb), a chromosome-scale genome assembly of the humpback puffer was sequenced as part of the Fish10K subproject of the Earth BioGenome Project.[6]
