Sea Beans vs. Molucca Beans

We recently found 2 "sea beans" on the beach whilst beach combing.  They were found a couple of months apart but on the same beach.  It is a westerly beach.


We searched for info on the internet and identified the ones we found. They are not "Molucca Beans" which are white/dark but another kind.  All seeds that wash up on shores around the world are collectively known as SEA BEANS.  Most are members of the legume family, though some are not.  Sea-beans often float because they have an internal air pocket within the seed.


Apparently these sea beans wash-up after journeying on sea currents such as the Gulf Stream, after events such as hurricanes that affect the Caribbean and African coasts.





1.  Size = 5.5cm.  It is a  dark brown colour and circular shaped with an indentation on the one edge.  It appears to be a Sea Heart - Entada Gigas.  The giant pods of this huge tropical legume vine are 1-2m.  Sea hearts are impervious to salt water, and even after floating in ocean water for several years.  It is also know as the Monkey Ladder Vine/Pod - The vines provide transport for monkeys high in the rain forest canopy.








2.  Size = 2.6cm x 1.3cm and is known as a the Mucuna seed / Hamburger seed and the one below comes from the Pacific coast of Costa Rica.






"A number of types of beans and large seeds are regularly washed up on the western shores of Britain, having been carried by the Gulf Stream from the Caribbean or South America, and there is a long tradition of these being found and treasured as amulets, under a variety of names—Lucky beans, Molucca beans, Sea beans, Virgin Mary's nuts, and so on. The tradition seems to have been particularly strong in Western Scotland, although the first known reference is in Richard Carew's Survey of Cornwall (1602), 27, who mentions their use ‘for women travailling in child-birth’. These beans were often worn on a string around the neck to avert witchcraft and the evil eye. Their use as commercial generic ‘lucky charms’ has persisted into the present day, and Vickery gives several instances of them being offered for sale at seaside resorts and elsewhere."  Read more: http://www.answers.com/topic/lucky-beans#ixzz1XLyYuMBC

----------------

We have previously read about Molucca Beans in the Western Isles and how they were considered lucky/unlucky according to their colour (white/dark). There is a long tradition of using them as amulets for good luck, banishment of ill luck or to ease childbirth.

Strange-looking sea creatures on National Geographic

The 2-foot-long (60-centimeter-long) fish is rather reclusive and not often seen, but blob sculpins have been known to dote on their young.

See it and other strange-looking sea creatures—including sea pens, dumbo octopus, and more—

Learning: Intertidal Zone

Here is some nice info for kids - all about the intertidal zone and the marine creatures that live there.

http://www.enchantedlearning.com/subjects/ocean/Intertidal.shtml

Extract:

The intertidal area (also called the littoral zone) is where the land and sea meet, between the high and low tide zones. This complex marine ecosystem is found along coastlines worldwide. It is rich in nutrients and oxygen and is home to a variety of organisms.

Much of this inhospitable environment is washed by the tides each day, so organisms that live here are adapted to huge daily changes in moisture, temperature, turbulence (from the water), and salinity.

Read all about it on by clicking on the link above.

An unusual find





It was a very low tide yesterday when we took our horses to the beach. We could access both cave areas via the front by walking on a small sandy beach instead of only throught the tunnel.

This is the first time we have been able to do this.

It was in this section that is not usually open to walk through, that my little sister found these creatures.

Not sure what they are.

They have a hard, brittle, transparent verticle half-shield on top. This half-shield has a raised crosshatch type of pattern. The underneath is some sort of limpet type creature but with a very blue jelly like substance including tentacles ?? Dont know if that describes it.

There were about 15-20 of them, but only in that area, on top of the sand. The tide only revealed that area for a very short time so it was not possible to do a full investigation and we had the horses with us.

Some after storm finds

Another sea potato, and its a beautiful perfect one :) even after a bad storm!

The other side






The vertebrae of a seal pup that washed up about a month ago. The sea and birds have cleaned them spotless.

Poor little seal pup had washed up, cleanly sliced in half - obviously some fishermen thought he was good for bait :(

A giant deep-sea crab has been caught in a fisherman's nets off the Isles of Scilly


The aquarium believes the crab is only the eighth of its kind brought up in the UK since 1900.

Due to the great depths at which they live, relatively little is known about giant box crabs.

Noise Pollution in oceans

I was reading about the effects of noise pollution on sea animals!


Extract:

Underwater noise pollution isn't just a nuisance to whales, it's lethal.

Massive bursts of underwater sound from military sonar and oil exploration, as well as the constant drone from ships, can deafen or kill whales and dolphins, and may be responsible for mass stranding events around the world.

As someone who has taken action to stop commercial whaling, I thought you'd also like to learn about some of ways IFAW is working to reduce the impact of ocean noise pollution to protect whales. Please join us on Facebook at
facebook.com/ifawhq to get the latest updates on our many campaigns to help whales.

Effects on whales

Blue whales once communicated across entire oceans. Today, the distance over which they can 'speak' to each other has shrunk by nine-tenths.

Whales use their own super-sensitive sonar to find food, explore their environment, woo mates, and keep in touch with distant relatives or group members. But noises from some human activities can drown out these natural sounds, leaving whales and dolphins disconnected and disoriented. In fact, ocean noise is already driving some marine mammals from their breeding and feeding grounds.

Military sonar produces such massive volumes of sound that whales and dolphins literally beach themselves to escape the underwater shockwave. Some of these beached whales are already injured - bleeding near their brains or ears - and even uninjured beached whales usually die.

Turning down the noise

Many countries use high-intensity active military sonar, including the United States. That's why IFAW has banded together with other conservation groups to address this deadly form of underwater noise pollution by identifying low-risk areas for sonar tests and establishing safety zones around vessels that emit sonar.

IFAW has used the US court system to restrict the use of naval sonar, winning two important victories to date. And IFAW's European offices are also working to ensure that underwater noise is officially recognised as a pollutant. This is the first step towards developing international regulations to control underwater noise

Scottish Sea Life Sanctuary - Oban

I am so excited, my parents are taking us to see the Scottish Sea Life Sanctuary - Oban. We have been doing the fishing industry as our theme at school and so far we have only gotten to see dead fish and dead prawns other kids have brought in.

I love sea LIFE and all the different sea creatures - it will be so awesome to see sea creatures that are alive and have not been killed !

Sea Wash Ball


I found this cluster on the beach and it was half a sea wash ball. :) Another one for my collection.




Here is a link to another 2 websites with photo's and info on the sea wash ball. http://themagnifyingglass.typepad.com/weblog/2009/06/sea-wash-balls.html and http://www.flickriver.com/photos/vintagechica/3650116893/


Transparent Mermaids Purse (see additional note on 28/4/2010: actually a Sea squirt - Corella parallelogramma)

I was walking on the beach one sunny day in April after a big storm when I found a lot of fresh green sea lettuce with these white-ish transparent mermaids purses on it with the babies still inside but without the curly things on them ( not a dogfish egg sac / mermaids purse)

We searched all over the internet but could not find out what they are!!



This is two of them in a bucket. They are still attached to the sea lettuce. We are going to ask someone to identify them.

This one's egg sac was already broken and it came out. It is under developed a bit like a
huge transparent tadpole.





28/4/2010 I finally found out what this is :) It is a
Sea squirt - Corella parallelogramma (with varying appearances)

Here is a link to one of the websites

We were looking through a book called Great British Marine Animals (2nd Edition) by Paul Nayor and found it on page 198. I was actually getting some information for a schoool project on the fishing industry and we have to do a presentation on one species. I also designed my own marine life wordsearch.
