Creature of the month: the rare Splendid Toadfish

Toadfish are found on the sand and mud bottoms of coastal waters worldwide. They usually have broad heads and drab colours, and look something like toads. The Splendid Toadfish, though, is different.

A diver coaxed this toadfish out from its den, and it swam approximately 100 yards before finally finding a suitable coral head to duck under.

As you can see, the Splendid Toadfish is attractively patterned in purple. Most of its fins are edged in yellow with the pelvic fin being entirely yellow. Its yellow mouth completes its livery.

Also known as the Coral Toadfish, Sanopus splendidus generally lives on sand under crevices or coral heads in clear water, from 10 to 25 m. It hunts at night, preying on small fishes, snails and polychaete worms.

The Splendid Toadfish was thought to be only found in Cozumel (Mexico) but sightings have also been reported in Belize at Glovers Reef and further north of Cozumel at Costa Occidental de Isla Mujeres. However, it is not widespread and is now classified as endangered by the IUCN Red List of Threatened Species.

In the past Cozumel suffered from increasing tourism and the building of a cruise ship dock in 1994. The island now takes much better care of its reefs, closing them periodically and operating a coral restoration program since 2017. Shockingly between 1984 and 2011, there was a 13% decline in live coral cover off Cozumel and an average 41% decline off Belize between 1970 and 2012.

Acoustic communication is critical to toadfish reproductive success, they make a buzzing sound that even divers can hear, but noise from cruise ships is thought to mask this as it is in the same bandwidth. Yet another problem for these unusual fish.

Have you been lucky enough to see one. Let us know.
