Evidence for aquatic lifestyles includes sclerotic rings that may have stabilized the eye under the pressure of water and strongly developed cranial joints, which may have supported the skull when consuming large fish and aquatic invertebrates.

Within birds, a medium-sized sclerotic ring indicates that the animal is a predator, a large sclerotic ring indicates that it is nocturnal, and the largest ring size indicates it is a nocturnal predator.

The orbit and the opening of its sclerotic ring are both small; the ratio between the diameter of its orbit to the length of its jaw is larger than " T . platyodon ", while the ratio between the internal diameter of its sclerotic ring to the diameter of its orbit is almost the same as the latter species.
