Whoa cool what is that? This is the whale shark.  Well which one is it you might ask.  The whale shark is indeed a shark not a whale.  Though they may look like a whale it is a massive shark.  It is not a whale is because it is a fish not a mammal.  The whale shark is a slow moving and filter feeding shark.  The whale shark is the largest extant fish.  The whale shark holds many records for sheer size. The species originated 60 million years ago.  The whale shark lives in tropical and warm oceans with a life spanned about 70 years.  Although the whale shark has a gigantic mouth it feeds mostly, not exclusively on plankton.  Plankton are microscopic plants and animals.  However Planet Earth has filmed a whale shark with a school of small fish eating them.  They have also filmed a whale shark coinciding with the mass of the spawning of fish and fed on all the eggs and sperm of the fish too.

Yuck you may say.  What is that.  Well folks let me tell you.  This ugly creature is the blobfish.  He was declared world ugliest animal as you might have heard on CNN.  Now some facts about the blobfish.  The blobfish is a deep see fish of the family Psychrolutidae. It lives in the deep waters off the cost of mainland Australia, New Zealand and Tasmania.  The average Blobfish are often shorter then 30cm.  They live between 2,000 to 3,900ft below sea level.  The pressure here is multiple dozens higher than at sea level.  The blobfish's flesh is slightly less dense than water so it can float without using energy to swim.  The blobfish has a big lack of muscle but that is not a disadvantage for the blobfish eats any edible matter.  The blobfish looks very different  out of the water than it does in it because of its low density flesh.
