Super Shark
Another critter followed with passion here on ESR is the shark. (Shark Tail Soup, Tiger Shark caught off the Vineyard)
Earlier this week while feeling very under the weather which was pretty low... I'd seen another news sound-bite about a newly discovered hybrid shark species. I'm just getting around to checking it out now.
The news never explained which species were mixed, so I had to chase down the info.
57 of the animals were found, n have successfully reproduced several generations of their new line, which also has a new territory.
The new species is a cross between two types of distinct Blacktips off the Australian East coast. One is the smaller sized, tropical Australian Blacktip, the other is the sub-tropical Common Blacktip, which both have different territories separated by water temperature. Hybridization is common in fish, but not sharks.
It's another edu-ma-cational, scientific, recent surprize that wowed me.....

How fascinating, Snaggle. You have to wonder what the prompt is for this cross-breeding...makes me wonder if they know they'll become stronger and more able to cope with global changes or something.
That is fascinating.
Talon, I really liked Ocean Science in College, n can't exclude the adaptation factors as the profs kept proclaiming things a certain way, but then I notice they are not ipso facto anymore! Food is most likely the change motovator. They can now move thru either temp zone.
Lynn, Sharks hold a special spot in my fascination index... Plus they are so primal n scary! I'm not as interested in 'Gators tho!
I wonder how they taste? mmmmmmmm mmmmmm
Neo, Kinda like sword-fish, I hear, but it depends on how you cook it...
If it bleeds, we can kill it!
Neo, you haven't heard yet that I don't eat fish anymore-
That is extremely interesting. Maybe they know they will be more able to cope with humans! You heard about the cross breed dog that was half pitbull and half collie didn't you? It would attack you then go for help. LOL (sorry, I just couldn't resist).
Sharks are amazing animals I have a supreme respect for indeed.
Interesting on the cross-breeding. Be interesting to see how it pans out!

Gran Annie, Poor old Lassie is rolling in her (one of his 8) grave! lol-
I'm thinking that wouldn't be an isolated incidence, n we'll need to be alot more careful of new ocean predators being unpredictable. Great Whites are now common off the Cape here, also a new thing...
JanF, Sharks deserve ultimate predator respect, I think. I've read n studied about the different species n their territories. There is even one lake, fresh-water shark. They have receptors that react to the electro-magnetic pulse of our moving muscles, n a White can hear your heartbeat half a mile away- (thank "Shark Week" dvd)
I love to swim in the open ocean water, but knowing what I do now really has slowed ne down- (see above answer to Annie).
Snaggle - After Japan I don't eat Tuna anymore. I don't trust anything coming out of the water anymore. :(
Neo, even Mischief suddenly doesn't like fish canned food anymore! Now all she'll touch is chicken n beef- that she used to never eat- very strange.
I'm just waiting for that miles deep junkpile in the pacific the size of CA to screw up the Whale n Shark migrations n breeding, before it hits Hawaii n the west coast. Never mind the radiation n oil contamination passing throughout the ocean's food chain now. I have to deal with allergy poisoning aenough as it is...
Slacking there Ev, time to bring it you!
swimming in your shark- infested blog-waters for as few minutes...
wishing you a wonderful ( short) winter.... Come spring, please.
Neo, only when I feel like it... This slow machine needs memory clearing again
David, Thanks for the wishes. Not having a good few weeks here. Yep it's cold!
Neo, I'm betting you wouldn't have the patience to wait for this slow puppy... I don't have the time!
You know I'm just teasing, I have plenty of time, but just can't think of anything useful to write atm.
Neo, I've been challenged trying to come up with topics n pics too recently. Time- very little on this constipated thing...
Hammer's work wonders. ;)
Neo, but then you wouldn't hear from me in a long time... I already did a post on Hamer Time-
