Some Strange Lobsters

Lobster shells are usually a blend of the three primary colors - red, yellow, and blue. Those colors mix to form the greenish-brown mottle of most lobsters.

This lobster, though, has no blue in half of its shell. The odds of this kind of mutation occurring are very rare - something like one in 50 million to 100 million. This one was caught in Maine in 2006.

Scientists say blue pigmentation comes from genetic chance, calculated to occur in 1 out of 4 million lobsters. This one was caught off New Jersey in 2003. It now resides at Sea World.

The blue pigment breaks down when a lobster is cooked, turning it bright orange-red, like the one above ( which is not cooked. )

Yellow is perhaps the rarest color morph of all. This one is missing both the red and blue pigments.

The lobster at right was caught off Nova Scotia in 2002. Not only is it precisely half albino, it is also a hermaphrodite - male on one side and female on the other - look closely at the tail.

Lobsters develop independently on each side of the body, which accounts for the two different claws, and also for bizarre patterns like this.

mitts

Diving gloves should be close-fitting, with long, gusseted, zippered, or Velcro gauntlets that overlap your suit sleeves. This is especially important with a drysuit, since the glove will protect the delicate wrist seal on the suit. Thin tropical gloves are of very limited use in the north - your gloves should be at least 5mm thick. Three-fingered mitts are much warmer than five-fingered gloves and are really not much clumsier. They are also much easier to get on and off, which makes me wonder why so few people use them. A little spray soap will make any glove easier to get on.

A hood is critical for maintaining warmth in the water. A good hood will be as close-fitting as possible, and have a generous collar for tucking into your wetsuit, thin skin-in seal around the face, and baffled vents in the top to release bubbles. A neck skirt is much less necessary with a drysuit, but it is a simple matter to cut one off if you don't like it. A neoprene cold-water hood should be at least 5-6mm thick.

The face-hole of a hood should be as small as possible - there is no reason to expose any skin here. The face seal of the hood should overlap your mask skirt, with just barely enough room below for your regulator. You can always trim out a too-small face-hole, but a too-big one pretty much negates any other good qualities a hood may have. Ideally, with mask and hood on, you should expose a small patch on each cheek, and no more.
