uff I (we) wish, but what about the announcement of seaworld expansion in San Diego, Orlando and San Antonio? xxxxthanks, but i need proof!!!
surprise why people choose go to aquatic park, when is beautiful go to the beach or for some specific areas to watch animals in their habitats..
kyaaaaaaaaa!!!! (◡‿◡✿)!!!! Im so shy!!!!
look at my oufit
that day I broke few hearts
(obviously after that beach party I cleaned all our junk!)
mmm to be honest, is my first time that i heard of pearlfish,according to advance aquarist, Some of the species can reach upwards of 50 cm in length when full grown. These fish are unique in that the adults normally live inside invertebrates, not only in sea cucumber, also in clams, sea squirts, and starfish in a commensal relationship (not harming their host). This trait is common throughout the Carapidae family.
wow 50 cm… but they are slender, scaleless, so probably the sea cucumber anus is alright :) well for them
awww you get it!!!
Yep, Here with my friend the giant chilean frog
YAS!!! DARWIN WAS RIGHT!!!
Embryonic cannibalism appears in polyandry, when females sharks copulate with multiples males (why not? do not judge them)
For convenience polyandry to occur, the costs of females resisting males must outweigh the costs of mating. Females tend to get injured by males during copulation because males bite onto their pectoral fins and bodies while mating. Females can also receive cloacal injuries caused by the male’s sexual organ, not all is fun. The existence of behavioural polyandry suggests there is sperm competition in sand tigers, whichcorresponds with the observation that males of this species store larger volumes of sperm than other sharks.
So, the only way to eliminate competition (I mean genetic competition), is a intrauterine way, depending on the most robust and well adapted baby shark.
Please, read the papers bellow, is interesting, and easy to understand
Also note the size differential between the hatchling (H) and an embryo (E) from the same uterus. interesting.
Shark Week 2014 is coming to an end tonight on The Discovery Channel, and with it its crazy, imaginary theories and legends.
I approached this year’s line-up with a lot of hesitation, and really did not get my hopes too high. Last year’s ridiculous Megalodon’s documentary made me cringe. Unfortunately, this year’s episodes came with their own shares of disappointments.
As expected, the science was left to be desired. Shark Week opened on Sunday with a 2-hour, fake documentary called “Shark of Darkness”. Has it really fooled anyone? Even with disclaimers that it was a dramatization, the special effects and acting were so bad that the show bordered on self-parody. Have you not learned anything from last year, Discovery? Surprise, Submarine is not real. A 60yr old, “Old Hitler” Monster Hammerhead does not exist along the coast of Florida. Sharkaggedon was completely skewed and advertised as truth. And yes, the Megalodon is STILL extinct. There is no new evidence. I will not bother watching this year’s Megalodon non-sense. At this point, even Sharknado was more entertaining. The Discovery Channel is, once again, ludicrous.
What everybody wants is science. Plain, simple, TRUE scientific facts to learn more about these great animals, what they do, what they eat, where they go, how they reproduce, how they interact, and how human beings impact them and their habitat.
I was very satisfied with this year’s features on deep-sea sharks (my favorite; I actually learned things!), great whites pupping grounds, shark tonic immobility, and the footage of the REMUS cam,but that’s about it. I know that, as a marine scientist, I have quite high expectations when anything marine-related airs on TV. But I have also many friends, who really do not know much about the oceans other than what I tell them, who crave this supposedly scientific week.
It really bothers me to know that a ridiculous amount of money is spent on making these mockumentaries. It completely defeats the original purpose of Shark Week. There are so many relevant and urgent shark issues that could have been addressed: shark cull policy in Western Australia, by catch, overfishing, shark finning, shark conservation, shark tagging for scientific research, endangered species, or even the O.R.C.A… But the channel decided to take the route of sensationalism, with mockumentaries about animals that do not exist or are extinct, and to once again perpetuate the idea of shark attacks and the fear of sharks. How many tweets did I read about people now being more afraid of going swimming in the ocean after watching Shark Week? Too many!
On top of that, producers of the show have lied to many scientists to get them on the show, and later completely edited their interviews to bring their own personal (fake) twist. Not cool, Discovery.
With that said, Shark Week has allowed many scientists, conservation organizations, and grassroots groups to use social media to really reach a larger audience and promote shark conservation. Sharks, and marine biology in general, very rarely get such exposure, and with the current trends of hashtags on many social media platforms, it is very easy for the general public to get their facts straight and to learn more about marine science and the many organizations doing work to save the sharks.
The Discovery Channel surprisingly does promote shark conservation not their own website, but how many of the millions of viewers will bother checking their website? Probably very few. There was not enough great episodes this year to counter-balance the ridiculousness and fallacy of the terrible ones. Shark Week needs to go back to its roots and restore a positive image on TV for these beautiful and necessary apex predators of our marine ecosystems.
