A sea serpent is an aquatic species of dragon that resides in the oceans. I do not see how our lack of exploration justifies the existence of an ice-breathing, aquatic draconian beast that devours ships and its accommodating sailors. Yet, very few websites contain the term ‘‘sea serpent’’ and ‘‘mythical’’, and many cryptozoologists appear to be entirely fixated on them. What are the best points against their existence?
There’s no point against their existence, and every reason to believe big unknown species live in the oceans.
not ‘serpents’ necessarily, but wiggly cold things.
That is a bold position you are taking. It will be only hours before you suffer a scathing rebuke from the rationalist pro-sea-serpent faction of the SDMB.
How can anything breathe a solid substance?
Doesn’t work that way. The person making claims that deviate from the established facts must support the claim with evidence. They don’t get to say that X exists and then demand that you debunk the claim.
There’s plenty of possibility that they exist, cuz that’s a lot of ocean out there, and we can’t watch all of it all the time. But there’s no such thing as evidence that something can’t exist, at least not the type that will persuade a cryptozoologist who’s fawning over his favorite myth.
Sea serpents? Absurd. If there were any way for Nessie to get out to the open ocean then they might have something but as it stands, nope.
If you’re just running Internet searches and counting hits, that doesn’t really tell you much about scientific consensus. Here you’re not even presenting us with the number of hits you found, or any websites; you’re making a hearsay claim about one or more searches we don’t know exactly how you performed about hearsay unknown people posted to the Internet. That’s not much to go on.
Degreed cryptozoologists from reputable institutes? Or just people calling themselves cryptozoologists?
What an interesting universe you must live in, where belief in all these mystical creatures is so firmly established in the general populace, and you stand proudly as a lone dissenter, boldly denying their existence.
I bet those cryptozoologist just don’t realize that they wereimprintedwhen they were very young.
Sea serpents must exist, otherwise we’d be up to our eyeballs in marine werewolves. 
Just because you have a degree in some other field doesn’t mean you don’t know your own profession.
You could somebody who retired from a law career go into cryptozoology rather than lobbying.
Lack of a biology degree doesn’t mean (s)he isn’t knowledgeable, competent, prepared, and serious.
But it’s okay, since we can convince them to stop breathing.
or trick them into the jungle with the carniverous plantesouras.
This. I think most people have no idea how much unknown there is in our seas.
Try this: there are hundreds of thousands of sperm whales now living. Their diet is almost exclusively medium to giant to colossal squid… many species and sizes of which are known only from the contents of sperm whale stomachs. (Even in the last whaling days of the 1940s, squid tentacles as big as a man’s body were reported.)
In other words, there are enough enormous squid in the oceans to feed several hundred thousand whales… and we have never seen some of those species alive, and many of them only in much smaller sizes. But they’re out there.
Moderating
CloneFive, your questions in this forum are becoming increasingly outlandish. (I note your previous one about whether werewolves are plausible.) It should be obvious that sea serpents are not “accepted as fact.” While we don’t mind you asking serious questions here, let’s not pretend questions are serious if they are not. More far-fetched questions like this one and the one on werewolves would be better placed in IMHO.
I’ll leave this one here for now, but let’s restrict GQ questions to phenomena there are reasons to believe could be real.

There is no such thing.
Lots of people have biology degrees. It doesn’t say ‘cryptozoology’ on the paperwork, but really all field biology is cryptobiology.
No field biology is cryptobiology.Cryptobiology/cryptozoology virtually by definition is pseudoscience.
Your link says the following:" is a **pseudoscience **involving the search for animals whose existence has not been proven."
Leave out ‘pseudo’, and you’ve got field biology.
It’s only pseudoscience to people who don’t understand what cryptobiology is, a search for real animals.
Science, real science, is full of solid results that started from stories, anecdotes, and the like.
New species are found all the time. Some are more ‘fantastic’ than others, but there
undeniably are unknown large species on Earth.
