AUSTRALIA ~ TO CREATE MARINE HAVEN ~ PART1

The following four minute animated video, “Coral Reefs: Polyps in Peril” is presented by WRI Insights ~ insights.wri.org ~ Submitted by Lauretta Burke on July 9, 2012
We strongly recommend you visit WRI’s site to read the full article,”Everything You Ever Wanted To Know About Coral Reefs“, . 

Ocean advocate Céline Cousteau and cartoonist Jim Toomey (creator of Sherman’s Lagoon) teamed up with the World Resources Institute to bring you “Coral Reefs: Polyps in Peril”. This short animated film tells the story of coral reefs with humor and admiration for these wondrous ecosystems.  Learn about the unique biology of coral reefs and their importance to people around the world, as well as the serious threats that they face due to overfishing, pollution, and climate change.  But don’t let that get you down!  The film also explores what individuals can do to help save coral reefs, including supporting sustainable seafood and tourism providers, reducing your CO2 footprint, and promoting coral reef conservation. Published to YouTube on Jul 9, 2012 by

As a prelude to this topic you might like to preview two of my previous blogs on the Great Barrier Reef:
1) “Great Barrier Reef Video” ~ posted March 6, 2012 ~ watch the National Geographic totally awesome and mesmerizing video, “Exploring Oceans: Great Barrier Reef”.

2) “Coral Reefs Are in Crisis” ~ posted May 15, 2012.

In my next blog, “Australia ~ To Create Marine Haven”, I will be including four videos and very interesting data about the species that inhabit the waters of Australia’s ocean and  the Great Barrier Reef: Marine Fish;  Hard Corals; Sponges and Echinoderms; Marine Reptiles; Marine Mammals and Mollusks.

I hope you all realize how vital the work being done by the World Resources Institute Insights is and will find a way to support their efforts ~ insights.wri.org. 

See you back here for Part 2

NUDIBRANCHS UPDATE ~ INCREDIBLE FACTS AND VIDEOS

Since I first posted “NUDIBRANCHS – SAY WHAT?”,  May 14, 2012), I’ve found the time to delve further into these fascinating and exotic ocean creatures.  You will be thrilled and amazed with the facts shared on these YouTube videos and the awesome video footage from around the world (Indonesia, Philippines, Bali)

First a few very interesting facts:

Nudibranch ~ means “naked gills”
Nudibranchs ~ are sea slugs
~ are beautifully colored tiny vessels of danger
~ store toxins/stinging cells they steal from their prey
~ more than 3,000 species
~ range in length from 1/4 inch to over 1 foot
~ are hermaphrodites (meaning they have both male and female sex organs)
~ are found in oceans from Antarctica to the tropics

I won’t overload you with information, for as they say, “a picture is worth a thousand words”.

“Nudibranchs”, by Jean-Michel Cousteau, Ocean Adventures ~uploaded by on Dec 5, 2008 ~ “They might be tiny, but nudibranchs can pack a poisonous punch. Learn more about these extraordinary creatures”.

 

This next video is amazing ~ the music, “The Tahiti Trot” is very artistically adapted to the bizarre antics of the nudibranchs  ~ an award winner in my opinion!!!

Colorful nudibranchs in Lembeh Indonesia” ~ uploaded by  Delveroudis on Jul 5, 2010 ~ “… But they are the most colorful creatures on Earth and their body patterns exceed the imagination of the best designers on the planet.”

“Nudebranches of Amed – Bali Reef Divers – Dive Bali” ~ uploaded by on Nov 9, 2010 ~ courtesy of Hero Productions ~ “These nudibranches were seen around Amed and Tulamben this season… wide variety of nudibranchs species around here… Night dives at Jemeluk are also a great opportunity to see these creatures!”

CANADIAN SHARKS THREATENED PLUS AWESOME VIDEO

Please read, “Help Save Canada‘s Sharks” Posted by staffblogger By Jarrett Corke, Shark Project Coordinator, WWF-Canada May 14, 2012

At the end of this topic I’ve included Jonathan Bird‘s video,Shark Biology” (Webisode 45) as I’m utterly amazed to learn so many astonishing facts, as Jonathan swims among the sharks.  What an incredible insight into this endangered species!   This is a 10 minute video and is definitely worth watching – A MUST SEE!!
 – Jonathan swims with blue sharks and tries to pet one – will he get bitten?…
 – an underwater cave hold a deep surprise…
 – Jonathan swims with the largest toother animal on earth, the sperm whale…

       PROTECTING CANADIAN SHARK POPULATIONS

http://www.wwf.ca/conservation/species/sharks/

Most sharks are vulnerable to overexploitation due to their slow growth, late maturity, low reproductive rates, and long life. Globally, sharks…are among the most threatened marine vertebrates on Earth. Large open-water or ‘pelagic’ sharks, such as great whites, are among the most threatened. According to the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, it is estimated that 60% of pelagic sharks are currently threatened with extinction. As many of these species are wide-ranging top predators, their loss may have far-reaching consequences for marine ecosystems.

Twenty-eight species of shark have been reported in Canadian waters … Close to half of these species are considered to be globally threatened; still most Canadians remain unaware that sharks regularly occur in our waters…

 
 

WHAT ARE THE MAIN THREATS TO SHARKS IN CANADIAN WATERS?

In Canada, unsustainable fishing practices, in particular the unintentional capture of sharks in fisheries targeting tunas, swordfish or groundfish have caused shark populations to drastically decline.

Bycatch – ‘Bycatch’, or the unintentional capture of non-target species in commercial fisheries, is perhaps the single most significant threat to sharks in Canadian waters. Little is known about the distribution of sharks in Canadian waters and ways to minimize the incidence of bycatch and overall shark mortality…

Demand for shark fins – Shark ‘finning’, the removal of only the fins from sharks and dumping the remainder while at sea, is illegal in Canada; however, Canada is importing unsustainable shark products, including fins, for consumption and, globally, the growing trade of shark fins has become a threat to many shark species. The fin trade today is considered to be a primary driver in shark exploitation.

Changes in the marine environment – Destructive fishing activities, marine waste and coastal developments can have serious impacts on marine habitats which sharks depend on. Climate change impacts on the marine ecosystem can also be a cause of concern for sharks, particularly in terms of how population distributions and habitats for sharks, as well as their prey, may be affected.

VIDEO OUTLINE of Jonathan Bird’s, “Blue Sharks“:

Jonathan joins Charlie Donilon on his shark charter boat in Rhode Island, Massachusetts, and learns about how shark tagging has shed light on the biology of and behavior of Blue sharks. Tagging has shown that these incredible swimmers actually migrate completely across the Atlantic ocean. Jonathan tries his hand at tagging a shark and then swims with Blue sharks. We also learn that Blue sharks are not nearly as vicious as they have been reputed to be, and the divers are actually able to pet the sharks!
