LOL Dave. That's a pretty precise head chop... was it the octopus?
Yep, part of my research looked at the predation of seahorses and the octopus was found to be a major predator.
Dead seahorse number 2 underwater:
So finding a dead Hippocampus underwater isn't impossible after all, just incredibly rare!!.
I double dog dare you to locate a dead hippocampus....they are hard enough to find when they are moving around.
