    The Famous Blobfish Photo Was Taken After Ut Skin Was Torn Off And They Normally Don't Look Like That

    A close-up of a deep-sea blobfish with a gelatinous body, illustrating weird ocean creatures and facts. The fact that the famous picture of the blobfish is not actually what a blobfish looks like. When scientists first found them, they did not know that the blobfish is not as resilient as other deep sea creatures, and That particular blobfish was pulled to the surface too quickly, and had its skin and flesh torn off from the immense force of rapid decompression. The blobfish in that photo has its skin torn off. What’s even worse, is that companies have made t shirts and even squishies entirely based off of this photo. It still chills me to this day.

    "Shark Spotters" Don't Spot Every Shark Nearing The Beach

    Great white shark swimming underwater, illustrating fascinating and scary facts about the ocean in an online group discussion. The concept of "Shark Spotters" is common where I live. People stand at a vantage point above popular beaches and look for sharks in the water to help ensure the safety of beach-go'ers. However, underwater sensors have shown us (well, shark biologists) that WAY MORE sharks swim very close to the beach than shark spotters can see. People really have no idea how many sharks they've probably encountered - that being said, very few sharks are actually dangerous to humans.
