Salt, Pepper, and a Case of Mistaken Identity

In 2016, a mystery unfolded at the Padilla Bay Reserve’s Breazeale Interpretive Center. Not long after its introduction, a juvenile wolf eel, aka Wolfy, vanished from the intertidal tank. After continuous daily checks for months, the staff deduced the fish had escaped or died. Ten months later, Chandler Colahan (the Reserve’s current education coordinator) was surprised to find that Wolfy had returned—bigger and healthier than ever.

Where did Wolfy go? It turns out that changing water levels had created a gap between the tank’s faux rocks and its wall. Wolfy had taken refuge in that crack, hidden from view but thriving on shrimp and crabs that wandered through. When Wolfy outgrew the den, he returned to the limelight.

In 2022, Reserve staff decided Wolfy was ready for love, and placed another juvenile wolf eel in the tank. For a while, the two kept to separate corners, but over time, they paired up, excavating a shared den in a bed of oyster shells. During that process, Reserve staff made a surprising discovery: Wolfy was actually a female! Fortunately for future generations’ sake, the new eel, with its larger jaw and pronounced forehead, was a male. Wolfy became “Pepper,” the new eel became “Salt,” and by November 2024, the duo was guarding a mass of eggs.

This mating was a success for the Reserve. Wolf eels, like many marine creatures, are notoriously difficult to study because of their secretive nature and preference for solitary dens. Salt and Pepper’s public displays of affection and their successful egg-laying are signs that the tank’s environment is conducive to natural behaviors. 

The story of Salt and Pepper highlights the mysteries of marine life, revealing that even in a controlled environment, nature can surprise. Beneath the water’s surface, there’s always more to discover.
