    Texas coquina
    Donax texasianus
    Family Donacidae - coquinas

    Good food source for fishy friends, but feed on phyto so don't usually last too long.

    Thatís what I identified them as, as well. Hopefully the fish will eat them, I just didnít want them to die and rot on my little ones dressed 🤣🤣

    I think the OP said snails, not clams. Most common snails in the surf zone are the moon snails, Polinices duplicata

    They are carnivorous and predatory, will eat clams, crabs, whatever they can latch on to. Put them in your tank if you wish, but without a lot of meat available, they won't last very long.

    good luck,
    Steve
