So I should probably begin with part 1…. Back in 1960, January 23rd to be precise, the first ever deep submersible dive occurred by two oceanographers, Don Walsh and Jacques Picard. Using the Bathyscaphe Trieste (above) they reached a depth of 10,911 m (35,797 ft) at the Challenger Deep section of the Mariana Trench, the deepest part of the ocean (11 km or about 7 miles deep). This so far, is still the only time this depth has ever been reached in the ocean by humans with it taking the Trieste five hours to reach the bottom and only being allowed 20 minutes at this depth due to the constraints of technology at the time.

The Smithsonian Tropical Research Institute has released a free iPhone app, for the identification of Pacific fish species. The species covered spans from Baja California to Ecuador, including the Galapagos.
The app evolved from the book, “Fishes of the Tropical Eastern Pacific” published in 1994. However, the app covers over 1,300 species allowing the identification of 10% of the world’s tropical fish species whereas the book only has 700. The app is free on iTunes: here and is potentially one of three apps according to iTunes descriptions.
Having downloaded and played around with this app it is very easy to use. It has a clear lay out containing a notebook section where you can compile your own lists and each page comes with a glossary section for any words used that aren’t understood. When you click on one fish you will also see other members of the family before it goes directly to the profile page, allowing for a perfect match. I like the feature of being able to find out the IUCN red list status which is available on each profile page. A useful little app that I would recommend to anyone needing to identify any pacific fish species!
This remarkable behavior was discovered just a few months ago; a black-marble jawfish (Stalix cf. histrio) following and mimicking a mimic octopus in one of my all-time favorite places at the center of marine biodiversity: the Lembeh Strait, Indonesia.
An outstanding find which shows just how much marine life has yet to teach us….

After watching Ric O’Barry in The Cove, it’s hard not to want to free any dolphin you come across in captivity. O’Barry has been at the forefront of dolphin rescue since the ‘70’s, after watching Kathy, one of the five dolphins who played Flipper, commit suicide in his arms. O’Barry is now working to free the largest member of the dolphin family: the orca. Along with a former SeaWorld trainer, two other marine mammal experts, and PETA (People for the Ethical Treatment of Animals), O’Barry is listed as a “near friend” of Tilikum and Katina from SeaWorld Orlando; and Corky, Kasatka, and Ulises from SeaWorld San Diego. The five orcas are named as plaintiffs in PETA’s lawsuit against SeaWorld. Tilikum is the orca that grabbed and killed his trainer in 2010.
PETA is asserting that the whales are, in effect, involuntary servants: held in captivity, ripped from their families in the wild, subject to sperm collection and artificial insemination, and forced to perform; all for SeaWorld’s profit. PETA is arguing that this is illegal… under the 13th Amendment, which abolished slavery in 1864. PETA claims this is the first suit of its kind: seeking to apply constitutional rights to animals.
