Super shark stuff.

Hi it's me Oscar and I think I'm just going to tell you the info and facts today.

" Contrary to popular belief, sharks aren't color blind. Divers have claimed for years that sharks are attracted to certain colors, such as the "yummy yellow" of some wetsuits. While color preference hasn't been proven, scientists know that some sharks that live in well-lit environments have developed cone cells that are just like the ones humans use to distinguish colors.

Sharks' skeletons are made entirely of cartilage, an elastic tissue that is much softer than bones. When a shark dies, salt from the ocean water completely dissolves its skeleton, leaving only the shark's teeth behind.

Sharks' eyes are on the sides of their heads, so they have an amazingly wide sight line spanning nearly 360 degrees. Their panoramic view of the undersea world is inhibited only by two blind spots, one in front of the snout and the other directly behind the head."

Did you know:

"Jaws wasn't the first time sharks have been given a bad rap. Ancient Greek historian Herodotus claimed that a group of sharks destroyed a Persian fleet in the 5th century B.C., which may have been the first time sharks were tagged with a killer reputation."
Well now I have finished my blog. Remember sharks aren't scary they are just different!
