Seamoth (Pegasidae)

Most scuba divers that visit the Maldives are anxious to observe large pelagic species, such as manta rays, whale sharks, napoleon wrasse and reef sharks. However, the vast array of smaller Maldivian fish provide an unending amount of eye candy for underwater explorers.

Seamoth, or Pegasidae

The seamoth, or Pegasidae, is a small Indo-Pacific family that includes 2 genera and 5 species, of which one has been spotted in the Maldives.

The seamoth is an easily overlooked (yet funky-looking) species. Seamoths are often missed by divers since their exterior is camouflaged by the sandy ocean floor. Adults tend to bury themselves in the sand during the day, making it even more difficult to apperciate this odd-looking underwater species.

Seamoths can be easily spotted during the spawing period, when the female is pregnant and males, after having changed their colors, are courting their female counterparts (which generally occurs at dusk).

Slender Seamoth, or Pegasis volitans

The Slender Seamoth, or Pegasis volitans, can be found in the Maldives, due in large part to its long pelagic stage.
