The novel «tongue-bite apparatus» in the knifefish family Notopteridae (Teleostei: Osteoglossomorpha): are kinematic patterns conserved within a clade? [PDF]
Osteoglossomorph fishes are unique in possessing a specialized feeding mechanism, the tongue-bite apparatus (TBA) involving the hyoid apparatus. The TBA is associated with two unique behaviour patterns – raking and open-mouth chewing – used to disable and macerate prey.

Food and feeding biology and some morphological adaptation of an exotic fish species Chitala ornata in a riverine habitat in Sri Lanka was studied from March 2003 to July 2004 to investigate its size-dependent dietary shifts. The stomach contents of C. ornata were volumetrically analyzed and relative abundance of different food categories of different ...

Além de sua ampla distribuição geográfica, a ordem Osteoglossiformes representa uma das mais antigas linhagens de Teleósteos. Estes peixes tiveram uma origem Gondwanica (~ 227 Mya) e sua distribuição atual é reflexo direto das movimentações tectônicas ocorridas ao longo da história evolutiva da Terra.

Fluctuating asymmetry (FA) is often used as an indicator of perturbed development. As organisms placed under greater stress, less energy is available to buffer their development compared to unstressed individuals and increasing levels of asymmetry. Therefore, individual asymmetry scores within a population can be used as a measure of an organism’s ...
