FIGURE 5 in Pomacentrus bangladeshius, a new species of damselfish (Perciformes, Pomacentridae) from Saint Martin's Island, Bangladesh
FIGURE 5. Maximum-likelihood tree constructed for COI gene sequences of Pomacentrus bangladeshius and its genetically closely related congeneric species retrieved from GenBank. Values of bootstrap support of>80% are shown above branches. The sequence of Pomacentrus auriventris Allen, 1991 marked by an asterisk (*) was obtained from the aquarium trade and therefore lacks locality information (Frédérich et al., 2013). Scale bar indicates number of nucleotide substitutions per site.

Fig. 1 in Evolution and diversity of ram-suction feeding in damselfishes (Pomacentridae)
Fig. 1 Phylogenetic relationships of the damselfishes studied for ram and suction performances. Circles at the tips indicated the different groups: nozooplanktivorous species with the cerato-mandibular (c-md) ligament, zooplanktivorous species with the c-md ligament, and zooplanktivorous without the cmd ligament. The shape of the head when the upper jaw is pro- truded is illustrated for each species; oral jaws are highlighted in green. The number of individuals used for both set of data (kinematic and morphological) and the mean of their head length are indicated

Unprecedented biting performance in herbivorous fish: how the complex biting system of Pomacentridae circumvents performance trade-offs
<p>It is well accepted that the complexity of functional systems may mitigate performance trade-offs. However, data supporting this theory is hard to find because it needs to be based on a functional system with different complexity levels in closely-related species. The Pomacentridae (damselfishes) provide an excellent opportunity to test the hypothesis because most of the species have two mouth-closing systems: the first using the <i>adductor mandibulae</i>, as in all teleost fishes, and a second one relying on the cerato-mandibular ligament (cmd), a synapomorphic trait of the family. Interestingly, some pomacentrids have secondarily lost the cmd ligament during evolution and therefore have a less complex mouth-closing system. Using dissection, kinematic analysis, and mathematical modeling, we demonstrated that the possession of two mouth-closing systems enabled grazing damselfishes to have a forceful and extremely fast bite. This combination challenges a major functional trade-off in fish jaw dynamics, as systems better suited for force transmission are usually less suited for speed transmission, and vice versa. The combination of grazing behavior, small and robust lower jaws (conferring high biting force), and an ultra-fast bite is unusual within actinopterygians. These attributes and their associated performance seem to be required conditions to colonize the ecological niche of farming, i.e., the maintenance of small filamentous algae crops serving as both food and storage.</p>
