Apologies for the lack of captions on my videos today as part of Global Science Show. I really want to help make all my videos as accessible as possible – but due to technical difficulties getting the captions to work today I had to post with them. As a compromise, although I know this is far from ideal, I have transcribed the videos myself in this file here to be read.
I hope to have a closed-caption option in all future videos!

Hi Everyone, My names elizabath aka MarineMumbles and I am a Marine Biologist and every single week I produce Youtube videos showing you the weird but wonderful world of sea creatures! So if that sounds like something you would like head over to my Youtube Channel and subscribe. But today I am going to be using my 10 minutes slot for the global science show to tell you as many weird and wonderful facts about marine life as possible in 10 minutes. Also if you like the facts I am telling you then I am also linking them to a Youtube video where I explain it in a lot more detail and a lot more weird and wonderful facts about that creature, so be sure to head over there to check that out. But why am I still talking, lets get on with the weird facts….

Anemones are far more than just a word nemo cant pronounce (anemone, ananamone, ananameneoneene) They are found around the world and you can find them rock poling on the rocky shore.They look like a blob sometimes when they hide their tentacles, but when their tentacles are out they are feeding and if you gently go and touch the tentacles you will realise they are sticky. Well what this stickiness is is the anemones actually trying too spear you with tiny little spears and sting you to eat you. Humans don’t have to worry about this, we are so big and our skin is so thick we don’t have to worry about getting stung by anemones because the tiny spears they use to shoot out in the water with stinging cells called nematocyst on them won’t go through our skin. But if you are a small marine creature and are swimming past an anemone you risk being stung captured and eaten! To find out more about this weird process and even weird anemone be sure to click the link to the video above where I have a whole video on it.

We know anemones are pretty quick but do you know sharks are squishy too? There are no bones in a shark instead sharks are made up of cartilage which is the same stuff our ears are made out of which is why we can do funny squidgy stuff with out ears and not well with our arms. But when it comes to study the evolution of sharks an sharks in the past theres no bones there to fossilise it can be pretty tricky. But luckily for us and people that study the, sharks have almost an infinite amount of teeth in their lifetime and that smells they loose their teeth a lot too. So a shark over the course of its lifetime can loose hundreds to though sands of theta which fossilise. Now the reason thats so great for us who don’t even study shark evolution, is that you can go fossilising on beaches and just find sharks teeth washed up. Some sharks teeth can be pretty cool and relatively small like this one, but click the video link above and you’ll see you can find some great big whoping sharks teeth in some of your local beaches so click the video link above to find them and eh watch me paint the shark that this was prehistorically.

You might thinks snails are boring, well thats because bless the land cousins snails but they give land snails a really boring wrap, but you know they just meh when compared to sea snails. Sea snails are far more interesting, far more weirder and yes far more deadly. And yes I genuinely mean deadly, there are some snails that are sadly. Cone snails feed on fish, but its a fish which moves very fast and a snail which moves very slowly so how does a cone snail catch a fish. It does this by shooting out a spear of really really strong toxin which kills the fish instantly, because if that fish starts to swim away its going to take that snail a whole week to catch up with the fish and by that time this fish is going to be eaten by something else. And in some species of cone snail this toxin is so strong its known to kill humans, so I wants lying when I said deadly. However you don’t have to worry about that in the UK, if you are a small marine creature you still do have to worry about snails, theres res one species of snails like periwinkle which feed and graze on seaweeds but there are some species of snail such as the dog whelk which actually feeds to marine species. They have a tool in their mouth which is basically a drill and it drills into the shell of some specie such as limpets its then quirts in digestive enzymes which melts and digests the limpet into ta smoothie and then out of the tiny whole the dog whelk has made it can slurp the rest of it back up so if you want to see me animate this gross process click the video link above.

From Snails to Snailfish – I’m Loving my transitions here – snails fish are the deepest fishy can finding living in the ocean at 8,000m that is incredible, thats really realy deep. Not only is it deep by the pressure is 800x than it would be here, so that fish is living with 800 times more pressure on it from being where it is just from living there. 8,000m isn’t actually the deepest part of our means, the deepest part is 11,035 m which if you want o now a really useless until of measurement thats 441 and a little bit blue whales which is the largest animal on the planet so thats a fact you can tell your friend. But whats incredible that for dos too that from 8,000m to the surface there is life in the ocean and I have broken down and painted my way down too the deep sea telling you what is the weirdest species right for the top down to the bottom and how they adapt to the pressure at 8,000 times more than land,… i cant do this video without doing this (under pressure song).

Well thats it from me here today from the Global Science Show video. If you want to support me and my science communication please head over to my youtube channel and hit that subscribe button. But please keep watching the global science show it is absolutely fantastic thing to be part of absolutely fantastic day and i am through though enjoying being part of if so all that left to say is to hand over to @rocksandscience and see what they have in store! Bye!
