In a large shallow intertidal pool with sandy substrate, bar Island.
Captured at 70 meters depth on Georges Bank during DFO Maritimes Winter Survey aboard the CCGS Cabot.
Captured at 70 meters depth on Georges Bank during DFO Maritimes Winter Bottom Trawl Survey aboard the CCGS Cabot. Captured an interesting individual that appears to be a fully leucistic specimen! Could also be a juvenile winter skate, specimen was not kept. Typically specimens under 40 cm are lumped together into L.erinaceus/L.occelatus unless obvious signs of L.erinaceus are present (I.e. rough patch near anus on females, or large pronounced sex organs on males).
Identified by Dr. Neil Bruce. Found attached to caudal peduncle of juvenile tarwhine.

After large storms this weekend there were 100s of these stars on the rocky beach. A few were still alive (barely) but most were dead. I've never seen them on the beach before.

Embedded in the mud and pebble of the Zostera bed here, this is the only dive site in Cape Ann where I have observed this species in shallow water
These corals were photographed and identified by the late Mr. Hans Ditlev, MSc (1946-2013) who was a coral specialist educated and working at Aarhus University, Denmark. These reported observations (c. 550 species, over 3.900 photos) are parts of his lifetime work with scleractinian taxonomy. Important parts of his collections are deposited at Phuket Marine Biological Center, Thailand; and Universiti Malaysia Sabah, Malaysia.
The corals are carefully identified by this expert in taxonomy and have a geographic position. The nomenclature follows WoRMS (marinespecies.org). However, the dates of collection or photographs are usually not given. The date is therefore arbitrarily set to 1. January 2000 to make it possible to enter them in iNaturalist. The high quality of the photos as well as the careful identification of a real specialist makes them valuable as references and will also, hopefully, contribute to the improvement of the AI system for Automated Image Recognition in iNaturalist. These photos are uploaded to iNaturalist with permission from Hans Ditlev’s wife, Mrs. Else Ditlev, Hornslet, Denmark.
Hans Ditlev published the book “A field-guide to the reef-building corals of the Indo-Pacific” in 1980. After that, he worked on a revision of this book, as he understood the importance of literature for identification as fundamentally important for work in ecology, evolution, conservation etc. His too early death motivated two colleagues to try to complete his work which resulted in the books “Indo-Pacific corals identified and illustrated by Hans Ditlev” by Jørgen Hylleberg & Tomas Cedhagen as authors; vol 1: viii+406 pp. 2015, Thailand National Science Museum; and vol 2: xxii+374 pp. 2018, Phuket Marine Biological Center. Hans Ditlev published scientific articles and described some new coral taxa.

I think this is a Phoxichilidium femoratum (Spiny-thigh Sea Spider) <1" across; placed for photos in a plastic container and released. I was helping with the PTMSC night low tide walk.
Habitat hypersaline lake.

The major solution salt in this lake is sodium carbonate (Cummings, J.M. 1940. Saline and Hydromagnesite Deposits of British Columbia, Bulletin No. 4. BC Dept of Mines: 160pp)
Maybe a Pholis clemensi (Longfin Gunnel)? This 3" fish was so small and thin we first thought it was a red ribbon worm. It was out of the water during the minus tide and gasping for air. We tried to move it to the water without touching it.
