The cute panda cub at San Diego Zoo is starting to take a peek at the big wide world around him.

During an examination on Wednesday, vets noted that the cub's eyes are beginning to open, which is right on track for this 45-day old panda.

It will take about 20 more days for his eyes to be fully open. The cub's ears, which began opening last week, have continued to progress.

The San Diego Zoo is following the Chinese cultural tradition of naming the giant panda after it is 100 days old.

The zoo will begin taking name suggestions on its website, sandiegozooglobal.org, next week.
