March 8, 2019,       Sea day before Cairns.          56/183

"If we were meant to stay in one place, we'd have roots instead of feet"   Rachel Wolchin

Howard has a cold today, as do many others.

Included below are pictures of the ship’s log showing our position, as we prepare to round the top of Australia.

Dr. Tyrone Ridgway gave a lecture detailing a few of the creatures on the Reef.   Many of the world's most venomous and dangerous 'things' live there, so the prospect of snorkelling tomorrow is somewhat daunting, but I am still going!

Dr. Tyrone loves sharks and is very concerned about the growing demand for shark fin soup, by the Chinese!

There are 3000 reefs and 900 islands. I have posted photos taken from his presentation, with comments.

 


Typical view from our balcony on a sea day.  One of the thousands of tropical islands in the Pacific.

Manta ray - Up to 25' across


Frog fish


Manta shrimp.  Has vision several times better than humans with a wider color spectrum capability.


Minke whale, gives birth around the reef and summer in Antarctic.  Each has distinctive markings.

 
Humpback whale, making dramatic comeback.  See chart


Coral releasing sperm and eggs, only a couple days a year.

Box jellyfish or sea wasp.  So venomous that contact with 2 metres of tentacle will kill you in 2 minutes.

 

 
Cleans algae on  coral.


Surgeon Fisgard fish that cleans algae.  Razor sharp fin


Parrot fish, eats coral and poops out 300 pounds of while sand per year.  Source of much of ocean's non-quartz sand.

Tiger shark


Another reef cleaner


Clown fish (Nemo) in stinging anenomi


Sea Cucumber -  Chinese are harvesting them to near extinction in some areas.
