Jay Garbose discovered a sea serpent off the shores of Juno Beach that even the Smithsonian is having a difficult time placine.  At this time, the Smithsonian is describing is as a Nemertean Worm, but they aren't positive on that description.  Until they can really narrow down on what this thing is, they are calling it "undescribed".  [Video]

Many discoveries have been made on Mars lately.  First, a giant pool of water ice was located at the south pole of the Red Planet and now seven possible cave entrances were found on the surface of the planet. 

The authors say that the possible discovery of caves on the Red Planet is significant.

The caves may be the only natural structures capable of protecting primitive life forms from micrometeoroids, UV radiation, solar flares and high energy particles that bombard the planet's surface.

A swimming ant has been discovered in North Queensland, Australia.  The polyrhachis sokolova "nest in submerged mangroves and survive by hiding in air pockets and then swimming to the surface. 

The ant was discovered by accident:

I [Dr. Simon Robson] was actually working with a film crew working on insects in the mangroves and they wanted to film one of these ants and I said, 'Well, lets put it on a rock in a puddle of water and that'll stop it going away and then you'll be able to film it,' and the ant promptly just leapt off the edge of the rock and swam across the water and disappeared.

There isn't much to the article, but what a cool find.

A new crustacean, named Kiwa hirsuta, was discovered in the South Pacific.  The Kiwa hirsuta "...resembles a lobster and is covered with what looks like silky, blond fur..."  Because it is so distinct from other species, a new family and genus were created for it.  New ocean species are discovered every year, but it's quite rare to find one that merits a new family.
