Living next to salt water, you never know what you'll see when you take a look into the water.
This is one of probably thousands of Ragged Sea Hares (Bursatella leachi) that have been grazing on algae in the water outside our place. This one was medium sized, and it was between 4 and 5 inches long. This is a gastropod molusk, and it moved pretty much like a huge snail without a shell.
These are Cannonball Jellyfish (Stomolophus meleagris). They are relatively solid and strong swimming for a jellyfish. This species is apparently quite common at times, but is not to be feared, as it has no stinging capabilities.
