Large eyeballs in diving ichthyosaurs
Article Abstract:
It has been established that ichthyosaurs have larger eyeballs than those of any other vertebrate. It is suggested that the genus Ophthalmosaurus, with particularly large and sensitive eyes, dived to depths of at least 500 mt. The large sclerotic ring aperture suggests that Ophthalmosaurus could probably identify point light sources. This would have been a beneficial skills in the mesopelagic layer of the ocean. The frequency of pathology arising from Caisson disease in the humeri and femora of a range of ichthyosaurs was investigated to determine whether Ophthalmosaurus was a deep diver.

Two-way mirrors
Article Abstract:
Homeless French people need respect and love to help them endure their suffering. Their bodies are wracked by ulcers and lesions, and, while they often cannot judge their own health needs, they are not welcomed into hospitals. They are rejected by society, instead living unnoticed lives of exclusion and poverty in which they are reduced to begging or drinking to survive.
