oval wooden Tea table with removable glass serving tray possibly hand carved

Table is oval and has what appears to be hand carving around the top. There is a removable glass serving tray. Under the tray is a hand carved design that I am not familiar with. I call it a "Merman" because it looks like a man of the sea with long hair at the tail end is a cherub on what appears to be a whale or fish and at the front (almost directly below the man's elbow) is another fish or whale. The table has carved claw feet and is in excellent condition for its age with exception to one of the legs appears to be slightly chipped. I know nothing about antiques to know what marks to look for or determine value or if the carving is something significant. If I had to guess I'd say it was a mahogany wood.
