Anemone
A sea anemone is a small sac, attached to the bottom by an adhesive foot, with a column shaped body ending in an oral disc. The mouth is in the middle of the oral disc, surrounded by tentacles armed with many cnidocytes, which are cells that function as a defense and as a means to capture prey. Cnidocytes contain cnidae, capsule-like organelles capable of everting, giving phylum Cnidaria its name. The cnidae that sting are called nematocysts. Each nematocyst contains a small vesicle filled with toxins—actinoporins—an inner filament and an external sensory hair. When the hair is touched, it mechanically triggers the cell explosion, a harpoon-like structure which attaches to organisms that trigger it, and injects a dose of poison in the flesh of the aggressor or prey. This gives the anemone its characteristic sticky feeling.
Killing Humpback Whales
Gales, N.J., Clapham, P.J. and Baker, C.S. A case for killing humpback whales?
Abstract: During the austral summer of 2007/08, hunting of Southern Hemisphere humpback whales will recommence after almost half a century of protection. The stated rationale for this hunt, by the Government of Japan, is to gather important scientific information for use in management. If the scientific need was defensible, and the proponents had accommodated reasonable conservation concerns, then criticisms of the hunt would be limited to philosophical issues. This is not the case. The program’s research objectives are unlikely to be achieved by lethal methods and do not address the principal research needs for SH humpback whales identified by the International Whaling Commission.

Save Wild BC Salmon
salmon fry
The rich waters of the British Columbia coast are home to recently returned humpback whales and vast shoals of sardines. Wild salmon feed bears, whales, eagles and forests that draw wilderness tourism into BC. Wild salmon also support commercial and tidal recreational fishing, which combined with, wilderness tourism, means wild salmon annually lure over $1.6 billion to BC, as compared with $600 million earned by farm fish. Why isn’t your government listening to the businesses that depend on wild salmon?
Sign and Send petition to Premier Gordon Campbell and the Honourable Ministers Pat Bell and Loyola to give wld salmon relief from sea lice by moving crucial fish farms:

New J pod Calf - J43
J43 baby photo from NOAA Fisheries (by Brad Hanson and Candi Emmons taken Wednesday, Nov. 7, 2007)
J43 was born this month to Samish/J14 (b.1974). This is the fifth calf for Samish one of the southern resident endangered killer whales. Samish's first born only survived four years which is common because built up environmental toxins are offloaded while nursing and new mothers can have some difficulty relative to older experienced female matriarchs. J43's siblings are big brother Riptide/J30 b.1995, Hy'shqa/J37 b.2001, and Suttels/J40 b.2004.

Robson Bight oil spill update
On October 19th, two months after the August 20th oil spill in Robson Bight, Canada's federal & provincial governments agreed to conduct an underwater investigation of the spill site, and to share the costs involved. This certainly came as good news, though the timing was odd in that the announcement came just hours after NGOs had released details of their plan to the media. Had the NGOs proceeded, the first ("side scan") phase of the investigation would have already been accomplished, and a week hence we could have had the answers we've been seeking. As things now stand, the investigation has been delayed, but given a suitable weather window, it should happen soon. If weather conditions permit, we should know the actual situation on the bottom of Robson Bight within a few weeks.
Here is a link to a more complete story we posted on our OrcaLab web site yesterday: http://www.orcalab.org/news-archive/orcalab_general/07-10-29.html
In case it's useful, we're also attaching our update as a Word file. Please feel free to do anything you wish with it.
As we say at the end of the story, our fingers are crossed!
As ever, this comes with our warmest wishes to you all, and our heartfelt THANKS for caring, and helping.
