For #molluscmonday !
I recently found a nice glass case and decided to set up a non-scientific display of random (and gorgeous) specimens from all families.

The last of my garden tomatoes... not bad considering it's mid-November in Canada 🌱🌿
Four red tomatoes sit on a table in front of some potted plants.

Here is a great report about the Farnham Memorial Garden project. I designed and built the garden and can't wait to see it next spring. Unfortunately, snow prevented me from attending the ceremony...

The first snow in Montreal. It brings a mix of joy and horror!
#snow #montreal
Snow covers a side street and parked cars. Tree branches hang downwards, covered by wet snow.

The Golden Volute (Provocator mirabilis) is a lovely, deep water (150-200 m) shell found off New Zealand. This one measures just over 100 mm
#mollusk #seashell #sciart #invertebrate
A pale orange shell lacking any pattern sits in a display case containing other specimens. The smooth shell is elongated, with a graceful contour. The aperture is slightly darker in colour.

Even though it's November, the foliage in this client's garden is still amazing! It must be said that most of these trees/shrubs are not native (Japanese Maple, Eunonymus, Cotinus).
🌱🌿💚
Trees and shrubs on a slope display some intense colours! The intense red one is a Japanese Maple. In front of it is a Eunonymus (Burning Bush). The orange tree to the right is a large Smoke Tree (Cotinus). The tall yellow trees in the back are native maples.

Good morning.
I don't know who did this, but I love you.
An abandoned building by the beach where a window overlooks the sea. The water through the window resembles a painting, so someone has scrawled Free Rothko on the wall.

The 'panerythra' forms of Map Cowries are gorgeous pink/red shells. In some cases, the base becomes callous with a white colour. Such specimens are said to have a 'candlewax' base and are highly prized!
#mollusk #seashell #sciart #invertebrate
A pinkish Map Cowrie sits on a blue background. The end is red in colour. A view of the base of the shell. The overall colour is pink. The base shows a milky white overcast. Orange teeth line the aperture.

I just received the rarest of all the Map Cowries - Leporicypraea mappa admirabilis from Tahiti. This specimen measures 71.4 mm and shows the typical dark blotch on the base.
#mollusk #gastropod #seashell #invertebrate
A light-coloured cowrie sits on a black background. The teeth are orange. A very dark blotch, typical for this subspecies, is present on the columelar side of the base. Dorsal view of the shell on a white background. A fine brown pattern covers the specimen. The ends are pale purple-grey.

After months of delays, I was finally able to finish the Farnham Memorial garden yesterday. An event is planned for Nov 9th. The perennials I just planted will be dormant shortly, so I will take a photo next season. Overall, I am happy with the results which look like the plans I made! 🌱 #montreal
A drawing of the proposed garden. The nearly completed garden. Large rocks fill a semi-circular garden bed. Small perennials (various Hosta, Hakonechloa, Astilbe and Iris - the two latter, not visible) are planted in the soil between the rocks.

Du Savel's cone (Conus dusaveli) is a large and stunning seashell known for it's beautiful colour and pattern. Once extremely rare and expensive, it is much more accessible nowadays. This specimen measures 75 mm and was collected off Balut Isl. in PI.
#mollusk #gastropods #seashell
An elongated cone shell sits on a white background. Alternating bands of different colours (dark brown, lavender and orange) cover the body of the shell. White markings are randomly dispersed over the series of bands. A view of the aperture showing the deep yellow colour of the interior.

Unbelievable start to the season! The city is so hyped up. It already looks like a playoff crowd. I can't wait to go see them destroy the Sabres on Monday. #Habs

WIP... happy with the progress so far. I am enjoying the metallic gouache! #art #artist #fineart #contemparyart #canadianart #drawing
A drawing on paper (in progress) is clipped to a drawing board. Two hazel eyes rendered in coloured pencil sit in the middle of an a seashell-derived pattern painted using gold-coloured paint (gouache). The work measures 18" x 24".

Happy Thanksgiving (Canadian!). That's a delish pumpkin, pear and leek soup being served to my mom by my sis-in-law... The turkey was great as usual!
A lovely Thanksgiving table. A pumpkim being used as a soup terrine!

The Atlantic Deer Cowrie (Macrocypraea cervus) is the largest of all cowries. These two specimens are both over 120 mm in length. They are native to Florida through to Brazil.
#invertebrate #mollusk #seashell #gastropod
Two shiny cowries lie on a white background. They are brown in colour with white spots. The shell on the left shows dark brown teeth lining the aperture.

The aptly-named Scorpion Spider Conch (Lambis scorpius) is a common shell popular amongst collectors. These specimens are from Cebu, Philippines.
#mollusk #gastropods #seashell
Three spider conchs sit on a white surface. They bear curved digitations giving the shells the appearance of scorpions with curved 'tails'. They are pale beige to orange in colour. The apertures have fine, purple stripes.

The hardscaping for the Farnham Memorial project went very well today! It helps when it's 30°C in October! I will plant the perennials towards the end of the month. 🌱🌿
Workers weed a section of a park along a semi-circular walkway. Large rocks and soil fill the semi-circular bed.

Hexaplex duplex is a stunning murex from West Africa. The colouration of the aperture is striking. This large specimen (over 160 mm) was taken by Senegalese fishermen.
#mollusk #seashell #gastropods
A spiny murex is held in my hands. The aperture is a mix of dark orange and pink. The rest of the shell is pale beige. Spines line the opening which is blocked by the dark operculum.
