New Jellyfish in Coffs Harbour

It seems humans know just about everything. This is a myth really. A new species of jellyfish has be seen in Coffs Harbour, NSW. It seems the marine creature has been there for a long time.

The mystery "object" is a box jellyfish that appears to be totally harmless. It is unlike the Irujandji and is smaller than the dangerous Chironex flecker box jellyfish. Fishermen have been seeing the new jellyfish for sometime but authorities took no notice. A game crew took photos of the animal last week.

Finally "professionals" acted and arrangements are being made to catch some specimens. Fish of all kinds are moving south as the temperature of the ocean increases due to climate change. It is believed the visiting jellyfish come from more northern climes. Usually jellyfish do not move south because they can be harmed by rougher seas. They prefer the warm, calmer tropics.

New Lobsters Found in Australia

New lobsters have been found in Australia. Six species new to Australia were discovered off the western. Two are new finds to the world. The most interesting is Galacantha subspinosa which is bright red in its live state, before being cooked. It will make only a small meal being only a few inched across.

There are hundreds of lobster species worldwide. They live in the shallows and the deep ocean. Those along the coast are related to crabs though they are called lobsters. The squat lobster is of this type having large front claws.

The red G. subspinosa new to Australia would fit well into aquatic themes parks because of its pretty color. This squat lobster is not in sufficient numbers to be an economic fishing species. Furthermore it has a small body which would not provide much "meat".

Shen Neng 1 Was Trying to Take a Shortcut

It's time Australia used pilots to guide container ships through the Barrier Reef. At least it would stop captains trying to take a shortcut via a dangerous channel in the reef. The Shen Neng 1 was a case in point. Experienced people involved with the reef have said this is indeed what the Shen Neng 1 was doing.

It was a case of incompetence, yes, but first and foremost it was an attempt to save money. The weather was good. It was daylight and visibility was good. The captain didn't just run the ship onto the reef. He was trying to negotiate a channel.

Unfortunately, putting pilots on board ships will not stop accidents happening. Before 2000 pilots were on board ships travelling on the inner route of the Barrier Reef. A pilot was on board six of the eight groundings that occurred. The question must be asked: Why are there so many groundings in an area of the world with good prevailing weather and good visibility? Apparently, the pilots were not to blame. It is claimed that crews are inexperienced. But, the Sheng Neng 1 was way off course and a pilot would have prevented that.
