Observer description: A man from Marine Animal Rescue came to check the seal was okay. He told me its a healthy individual, approx one year old. Observer notes: The hotel staff told me that the seal had been seen several times on that beach over the weekend (28th Feb/1stMarch). it was swimming out when the tide came in and rested when it was out. I have more photos in high resolution. Let me know if you would like them.
