Pododesmus (Monia) macroschisma

The false pacific jingle shell, or rock oyster, often comes ashore on Taylor Beach attached to the holdfasts of kelp.

Various species of kelp have attached their holdfasts to this rock oyster shell, leading to it being detached and carried ashore on Taylor Beach.

River Otter: Lontra canadensis on the Metchosin Coastline

When she was an ecoguardian at Race Rocks in 2010, Raisa Mirza took this excellent photo of a river otter, just out of the water, eating a female kelp greenling .

River otters are fairly common along our shores.  Thus an entry for our species posts. In four stretches of shoreline in particular, we can expect to find them, where they have dens and produce offspring yearly.

1.  At Race Rocks
2. In Pedder Bay
3  At the entrance to Gooch Creek
4.  Along the Taylor Beach blufffs.

 

The Pearson College Marine Science reference has several references and images available on river otters.   riverotters atpc

Family:  Mustelidae
Subfamily:  Lutrinae
Genus:  Lontra
Species:  canadensis pacifica (Schreber, 1977)

One should be cautioned when walking dogs on Taylor Beach to restrain them if otters are in the area. Otters have been known to attack even large dogs that have pursued them into the ocean.

Subfamily: Merginae
Genus: Mergus
Species: M. serrator
Common name : Red-breasted Merganser

Mergansers nest in the fresh-water lakes of the north and then migrate to the Pacific Coastal waters where they feed on small forage fish in the winter. In the past  few weeks a large flock of female red-breasted and possibly mixed common mergansers has been working the waters off Taylor Beach.

They may be joined by males in the spring.

Octopus (Enteroctopus dofleini) on Taylor Beach

The remains of an Octopus on Taylor Beach

Not a great picture but the remains of evidence that offshore of Taylor Beach, the giant pacific octopus goes through its life cycle, which is very short.. just a few years.

Liparidae ( snail fish) today on Taylor Beach

My dog led me to this very unusual fish washed up on the shore today, Nov. 12 -2014.  There was a brisk cold wind blowing from the North east, with a two-foot chop.

I am posting it here to try to get it identified.

A good suggestion has been made by Rick Harbo that it is a snail fish (Liparidae)

Also From Fishbase:
“Liparidae – (Snailfishes)
Distribution: Arctic to Antarctic, Atlantic, and Pacific. Body elongate, scaleless (small prickles in some) and skin jellylike; dorsal fin (28-82 soft rays) and anal fin (24-76 soft rays) long, confluent, or nearly so with caudal fin; pelvic fin (disc) absent in species of Paraliparis and in the monotypic Nectoliparis; nostrils single or paired (usually in Liparis); vertebrae 38-86. Maximum length about 50 cm. Occur from tidepools to depths of over 7,000 m.”

Below: I took this image in late November of a red-breasted merganser female eating what may be one of these fish. I am not sure if she actually got it down whole!

The Hooded nudibranch: Melibe leonina

Laura Verhegge has posted this note about Melibe leonina, seen today in Pedder Bay  on the Pearson College Marine Science website

Seabirds abundant on Taylor Beach today

I had thought that the Mergansers which started showing up on Taylor Beach this past week were Common Merganser females. Now I am not so sure, as most of them lok more like Red-breasted merganser females . Click for enlargement.

If all projects for the Pacific North-west go ahead as planned, over 1000 more ships of this size above the high number already using this waterway, will be transiting these waters each year, all carrying bunker and diesel fuel and if Kinder Morgan has its way 350 a year carrying highly toxic dilbit.

See the Census Page on the seabirds showing up in the last few weeks.

Common Loons ( Gavia immer) off shore today

Nov 5: Yesterday  there were several loons offshore from Taylor Beach. They normally stay over 100 m off shore, so photography without a telephoto is challenging. I think the following images are of two Common Loons (Gavia immer) in various stages of maturity.

Ship Noise and its Effect on Killer Whales

In April, 2014 I attended the Salish Sea Ecosystem Conference in Seattle. One of the presentations  which surprized me showed  the risk to the Southern resident Killer Whale populations from Noise Imapcts in the Salish Sra under Commercial shipping growth Scenarios. Following is a reference to Beam Reach which carries a summary presentation of this. — Scott Veirs, Beam Reach Marine Science & Sustainability; Val Veirs, Colorado College; Jason Wood, Sea Mammal Research Unit

soundimpacticonEmazing talk on fossil fuel ship noise & killer whales

This afternoon I’m giving a talk at the 2014 Salish Sea Ecosystem Conference in which I present our estimates of sound pressure levels from commercial ships in Haro Strait, the core of the summertime critical habitat for the Southern Resident killer whales. I also take a first look at noise impacts of the current tanker and bulk carrier fleets and ask how those impacts may change if a suite of proposed fossil fuel export facilities are added to the Salish Sea.

Surf Scoter (Melanitta perspicillata) off Taylor Beach

Surf Scoter off Taylor Beach: photo by Garry Fletcher

From September on through winter we see flocks of Surf Scoters feeding offshore on Taylor Beach . Today they were 100 metres offshore. They usually do not approach the shore as closely as the grebes and loons.

“The British Columbia Ministry of Environment, Land and Parks (BC Conservation Data Centre 2000) has designated them as a “Blue Listed”  species. Blue List taxa are of special concern because of characteristics that make them particularly sensitive to disturbance from human activities or natural events. Blue-listed taxa are at risk, but are not extirpated, endangered or threatened (Master 1991). “(SFU biology)
