Here’s another weird underwater creature for swim nightmare fuel

What’s wrong with me that I like looking at all the scary things in the sea?

A few months ago, I collected some the related fears of open water, and suggested we use Megalohydrothalassophobia, as a name for the fear of underwater creatures. Here’s another one for the causal list.  The Cascade creature, aka deepstar enigmatica, or the Placental jellyfish, apparently though not rare, but only seen intact a few times. Checking around it seems like it’s about 50cm in diameter, and is usually a more common bell shape, but the turbulence from the submarine turns it inside out and give it that really creepy motion.

Anyone who’s ever had an unexpected encounter with a plastic bag while swimming will shudder at this one. Plastic bags are scarier than jellyfish.

More details/speculation on the creature here.

Open water swimming fears listed

I was thinking about the fears that hinder open water swimmers or potential open water swimmers. It always amazes me how many non-swimmers (or even swimmers) have a seemingly visceral fear of even the idea of swimming over deep water in the dark or imagining themselves over a deep section of sea with potential movement under them. Here’s a provisional list of relevant fears. I’ve excluded basic fear of water, it seems inappropriate for swimmers.

Autophobia is a fear of being alone.

Bathophobia is a fear of depths or deep things, (for swimmers who dislike swimming over deep water).

Cryophobia, Frigophobia or Cheimatophobia is a fear of cold, cold weather or cold things. Also known as Psychophobia!

Cnidophobia is a fear of stings. Surprisingly, there is no specific clinical phobia for jellyfish.

Dishabiliophobia is fear of undressing in front of someone, probably relevant when you changing by the side of the road in Sandycove.

Eleutherophobia is a fear of freedom. Seriously, are we ever as free as when we are open water swimming?

Eosophobia is fear of dawn or daylight. A bit difficult for an overnight swim.

Francophobia or Gallophobia is a fear of France or French things. That’s the Channel out then.

Galeophobia or Selachophobia is a fear of sharks.

Ichthyophobia is a fear of fish.

Kymophobia or Cymophobia is a fear of waves.

Limnophobia is a fear of lakes.

Megalophobia is a fear of large things and Mycrophobia is a fear of small things. Both are prevalent in the sea.

Myctophobia / Nyctophobia / Scotophobia / Achluophobia / Lygophobia: fear of the dark or darkness. That’s a whole lot of fear right there.

Ostraconophobia is a fear of shellfish.

Ornithophobia is a fear of birds.

Osmophobia is a fear of smells or odours.

Thalassophobia is a fear of the sea.

I’ve seen Megalohydrothalassophobia  proposed as a fear of the unknown and-or large objects underwater, a useful word for many people, but unlike the others not a medically recognised phobia. Yet.
