Notes: River otters are shy but playful creatures that spend much of their time just splashing around. They don't like human encroachment and are uncommon nowadays.
The inshore wrecks are sometimes surrounded by the empty shells of Surf Clams Spisula solidissima, right, to 7" across. Large numbers of the white shells also wash up on beaches. Surf Clams are found subtidally down to 100 feet ( which makes you wonder why they are called surf clams. )
Tiny angel wing-shaped Coquina clams Donax variabilis less than 1 inch long do live in the surf, on wave-tossed sandy beaches.
