Potential adaptions / features for life adapted to the level of atmospheric pressure given?

Atmospheric composition:

• | 2% Trace gases | 58% Nitrogen | 26% Oxygen | 11% Argon | 3% Carbon dioxide |

Average surface temperature:

• 36 degrees Celsius

Surface gravity:

• 1.36x Earth gravity

Info regarding of altitude, pressure, and atmospheric density:

altitude    pressure    density 
(meters)    (atm)       (kg/m^3)
0           17          10 
1000        15.3        9
2000        13.8        8.1
3000        12.5        7.3
4000        11.3        6.6
5000        10.1        6
10000        6          3.6
15000        3.6        2.1
20000        2.2        1.3
30000        0.8        0.5
40000        0.3        0.2
50000        0.1        0.06

What adaptations would creatures normally have on this world based on the high pressures of the atmosphere given? Would they have looser bones? Pressurized gas within the bones? Etc? If possible, give detailed hypothetical answers, I'll be glad if examples are given in the answers for the question I'm asking
