[@Nikki0417]

The first time I heard about sea snakes was watching Steve Irwin. He talked about how highly venomous they were while holding one. I think I was like 10 or 11 at the time, but I remember thinking "that seems insane." Miss that dude.

[@elonweintraub9758]

They might be much more venomous than a cobra, but they are also completely docile. Researchers regularly handle them barehanded to tag them and take their measurements, as do fishers when the snakes get stuck in nets. I still wouldn't try it without training, but it's apparently far less insane than it seems.

[@RealBradMiller]

I grew up on Steve Irwin, and know exactly where I was when I found out about his passing. Deeply missed!

[@snipelite94]

One poisonous critter eventually jabbed him though, I vaguely remember he took a lot of flak for carrying his baby around crocs or alligators. Dangerous creatures can behave randomly, and it was irresponsible to take a "civilian" into danger like that. I'll grant you, that his excitement was infectious, and he bubbled over with enthusiasm leading to a devoted following, but recklessness will run your luck out one day.

[@safaiaryu12]

amazing! I thought if it were temperature tolerance, eventually some would traverse the current and setup in the south Atlantic, but I never thought about needing fresh floating rainwater to survive

[@StonedtotheBones13]

And it's the kind of thing that years ago we would be like "nah, that sounds impossible."

[@liamnixon4428]

Yeah. Near the southern tip of Africa is a desert, and you can see why there's no rainwater there. In fact, sea snakes can't even traverse up the Red Sea and pass through the Suez Canal, because of the Sahara-Arabian deserts, and passing through the Panama canal and its locks is hard for a snake that acts as an oversized Plankton.

[@emotionalfriendone43]

@@StonedtotheBones13so science got it wrong?!? 😮

[@Fledhyris]

@@emotionalfriendone43 Science just hadn't investigated at that point. We simply didn't know. Science is not omniscient, it takes years (sometimes decades) of rigorous, difficult, expensive research by dedicated individuals who are often working for little or no funding (because who is interested in sea snakes?) so there's just really not a lot of science going on in many areas that don't seem economically attractive to universities, Big Pharma, NASA, the military and so on. And the whole area of behavioural biology - trying to understand plants and animals within a holistic context of their evolution, genetics, environment, and natural (not laboratory) behaviour - is very recent, it only really started taking off midway through the 20th century. tldr; science is a lot more difficult and complicated than the internet generation give it credit for. Cut those scientists some slack! :)

Okay, awesome episode in general, but I had never heard about fresh water floating on top of ocean water?!

6:09 The Panama Canal is powered by an uphill reservoir, so that water flows outward at both ends. I image this would discourage species from crossing the isthmus.

[@pamelah6431]

PHEW.

[@joedellinger9437]

Also fresh water kills marine species.

[@boxsterman77]

It’s not the flow, it’s the locks and the sequence an animal would have to go through to traverse the isthmus. 1. Make it to one lock and avoid being squished by ships that barely fit. Wait until lock fills up to next level. When gates open, move out with the ship into the next lock. Keep repeating until you are at the level of Lake Gatun traverse the lake. Get on lock on other side. Take the series of locks down but I could see a small number making it to the lake and there breeding sufficiently. It’s a tropical paradise. Keep in mind lampreys had to negotiable locks in the St Lawrence seaway-and they did. The old Panama Canal is “powered” by damning a river,causing a reservoir and directing the captured water out both sets of locks (Caribbean and Pacific).

The volume of air those long skinny lungs (or that long skinny lung-I seem to remember most snakes have one functioning lung) can hold has gotta be pretty limited.

Yellow bellied sea snakes are found off the west coast of Mexico, but don't usually get up to California. Don't usually, but, a few times recently, they've been seen here. In 2015 one was found at Oxnard (Ventura County), in 2018 one turned up on the sand at Newport Beach (Orange County, south of Los Angeles County) and in 2019 one was caught in San Diego. I would suspect that this growing presence is due to warming sea temperatures, as the current along the California coast flows down from the north.

We a particular type of snakes that love to swim in the rivers and hunt fish. They have orange and black stripes. They can be confusing considering we also have a couple of other terrestrial snake species that have a similar color scheme. A friend who loves fishing bought a boat, painted it like the snake's stripes and named it with the water snake's name. The funny thing is he and his fellow fishing friends are terrified of these snakes. These snakes are attracted to disturbances in the water which is not ideal when my friends were spearfishing. In one occasion, they encountered by a couple of these snakes at their favourite spot. They cut them down only to discover that they were surrounded by countless numbers of these snakes. The unusual number of snakes in one spot definitely puzzled my my friends but when they saw there are specimens that were far larger than they usually encountered...they decided to call it a night.
