Hi Tom,
The cetacean could be Indo-Pacific Humpback Dolphin (Sousa chinensis). They are very pale and larger than Finless Porpoise.
According to the Mammals of China (Smith and Xie) their range does not reach as far north as Liaoning but that does not mean they don't occur and, of course, there could be a range expansion to the north due to warming seas..
Hopefully someone with experience of Chinese cetaceans will be able to confirm the identity.
Cheers, Terry
firtreesjohn, thanks so much for identifying the butterfly on the previous page and others. Here are a few more
I had about 1 hour today and quickly headed out and found a Little Gull among the many Black-headed and Black-tailed Gulls on the mudflat as the tide receded. This is my second record here in the Dalian area but the first for the pond area. Thanks to Mr. Townshend for on-the-spot ID tips and confirmation on the phone!
LITTLE GULL - 1
Interesting observation. Most birders would be excited about 8 chinese egrets and less so about the little gull.
All depends on your frame of reference.
