That price is the very absence of the selenodont specializations, the most obvious of which is foregut fermentation. |
In the Middle and Late Silurian odd specializations, like lacunose septa and complex septal formations in the body chamber, develop. |
Skilled trades such as fishing, carpentry, and masonry work tend to be family specializations. |
However, some primates such as apes, spider monkeys, and lorises have morphological and behavioral specializations that may enhance efficiency during vertical climbing. |
These advances culminated in the modern bony fish, or teleosts, which show a tremendous diversity of mouth parts and feeding specializations. |
The central retina, or macula, and the centermost macula, or fovea, exhibit structural and cellular specializations for fine central acuity. |
