Kissing gourami By increasing the angle of opening of the jaw, this joint allows kissing gourami to access to these nutrients. "H. temminkii", however, is the only species known that uses this articulation in this way. The intramandibular joint divides the jaw into two independent elements so that it increases the degrees of freedom and the potential number of ways of getting food. This articulation, although its mechanism and anatomy are still being studied in a hurry, results in an adaptation of Helodoma temminkii and its feeding. Shallow, slow-moving, and thickly vegetated backwaters are the kissing gourami's natural habitat. They are midwater
