The blog post about blob fish!

Hey everyone,
sorry I haven't posted in a while I hope this post makes up for it! 
The blob fish!
Latin name of blob fish: Psychrolutes marcidus. 

Blob fish live in the waters near Australia and Tasmania. They live at depths of 2,000-3,900 feet. This is 80 times denser then the water at sea level. Since they live in water that has a super high density they have gas bladders so that they don't explode. A normal animal or mammal on the other hand would explode. This is why it is so hard to get pictures of them. This is the best picture that I have found so far. 
I wouldn't say that they are very attractive! What do you think? 
It also makes it hard to study them because if you do catch them and bring them to sea level or higher they are most likely going to explode on you! :/(I hope your not eating lunch!) They are going extinct rapidly. This is because fisher men that are catching fish with huge nets are catching them. They proceed to take the fish that they caught out of the water killing the blob fish. Plus if you do catch blob fish with other fish you want to eat, you can eat the blob fish. So there really isn't any reason to catch them since they die right after they get to the sea level and you can't eat them like other fish. Just these two reasons make the blob fish extremely rare. 

Body features
The most distinct feature of the blob fish is the human like face. If you get a straight on picture of a blob fish you will she that they have a nose, mouth with lips, and small eyes. 












Surprisingly the head, what I think looks the heaviest only weighs 1/3 of there body weight! So they small tail that they have weighs much more then it looks like it does. 

Daily life
If you think about it life on earth is much more fun then life in the sea for a blob fish. For most of the blob fishes life they are letting the ocean currents move them in the direction that they wind is going. Even when they eat the lobsters, crabs, mollusks, urchins and other slow moving fish and plants that are loose and are floating in the current all they do is open there mouth. The funny thing is that they don't have any muscles. So how do they move is the question that sprang to mind when I read this. Apparently they are made of a gelatinous mass that has a density that is lighter than water. So they are so light that they can move themselves with having any muscle. When the blob fish are fully grown they reach a length of about a foot. 

Reproduction
The only other thing they do in there life besides eat and move with the current is mate. Females only mate when a male comes into view. But they only really have to mate once because every time a female blob fish mates with a male blob fish she produces 1,000 pink eggs. Yeah, that's a lot of eggs! The male wanders off to find a new mate while the female blob fish hovers over the eggs as if to keep them safe from larger fish that would love some pink little eggs for brunch. 
Here is my drawing of a blob fish:
