Otter Moon : Otter meaning is also closely connected to lunar symbolism. Water, the moon and otters have a long, symbolic history together. Indeed, the Algonquin named one of their full moons the "otter moon". Otters are most active in the spring and summer. Typically the otter moon would be the first full moon after the spring equinox.
