@gugunderwater: “Leptocephalus” is the term used to describe larval eels at this stage. And this is a moray at ~3-4cm long. Based on my observations, they spend 98% of their time hyperactively swimming, but every so often, they coil up into various circles or ovals. No one knows why, but a reasonable theory is that it’s a defense mechanism wherein its vulnerable head is surrounded by its body. ...#leptocephalus #eel #moray #morayeel #thatsamoray #larvalfish #blackwater #blackwaterdiving #gug chrisgug #gug
