13 Sea Creatures You Might not Want to See on a Snorkel or Diving Trip

Does it ever cross your mind what else might be in the ocean with you? Well I’ll bet it’s none of what you are about to see. Below is the top 13 creatures that might make you think twice the next time you go for a swim!

#13 Water Bear


As the first creatures known to have survived the vacuum of space, these critters are less than 1 mm in length.

#12 Mola Mola


Also known as a sunfish, this largest bony fish in the world averages at a weight of 1 ton!

#11 Red-Lipped Batfish


Looks like she’s all dolled up but there’s no date! Pucker up!

#10 Ribbon Eel


Ribbon eels grow to nearly a foot in length – one can capture but not keep them as they don’t survive well in captivity.

#9 Pink See-Thru Fantasia


Well I’m sure these guys would have zero trouble getting through security at the airport!!

#8 Squidworm


This creature’s ten tentacles protruding from the body, allowing it to taste and smell its surroundings.

#7 Sarcastic Fringehead


Wouldn’t want to get in an argument with this guy!

#6 Barreleye


Never have to guess what’s on his mind!

#5 Blobfish


This bottom-sea-dweller looks a bit sad – he probably doesn’t have much company!

#4 Globin Shark



Clearly didn’t learn to chew before swallowing!

#3 Salp


As they pump water through their bodies, they affect the content of carbon in the water – also affecting climate change.

#2 Bobbit Worm


Relative of Lorena?

And for #1…Drumroll…

#1 Comb Jelly


The rainbow/halo affect you see is light reflecting off the hair-like cilia used to propel the creature through the water. Well, thankfully most of these creatures are bottom-dwellers. Remember them the next time you swim – you never know what else might be with you out there…
