Now Available: Illustrated Key to the Chitons (Gulf of Alaska south to the Oregonian Province)

An illustrated key to the Chitons (Polyplacophora) (Gulf of Alaska south to the Oregonian Province) is now available on E-Fauna BC.  Compiled by marine invertebrate specialist Aaron Baldwin, and using photos, this illustrated key provides identification assistance for common species of chitons found in this region.

In his introduction to the key, Baldwin provides insight into the life of chitons:  "Intertidal chitons tend to remain under rocks during the daytime but become active at night. This is especially true for those species that occur in warmer climes. Amazingly, chitons have “eyes” on the tops of their shells. Some chitons have as many as 11,000 tiny little light receptors! It is possible that they use these to tell day from night. It is also likely that they are used in a fashion similar to the eyes of sea stars for detecting shadows passing over them so that they can clamp tightly to the substrate." 

Aaron is the marine invertebrate editor for E-Fauna BC and a fisheries biologist with the Alaskan Department of Fish and Game.

Checklist of the Bees of British Columbia, 2017, Now Available

Thanks to the extensive scientific work of entomologists Cory Sheffield and Jennifer Heron, a checklist of the Bees of British Columbia is now available on E-Fauna BC. This includes all genera of bees found in the province, including Colletes, Hylaeus, Andrena, Osmia and Bombus.  This checklist will eventually be replaced by one that will include a detailed introduction to the bees by these authors. 

E-Fauna BC presently provides several checklists for the Order Hymenoptera, including those for ants, bumblebees, speciform wasps, spider wasps, and yellow jackets and paper wasps.  However, we do not yet provide checklists for all groups in the Hymenoptera.

View checklists on our checklists page.

Using vodka to further science: The photomicrography of Ian Gardiner

E-Fauna photographer Ian Gardiner has taken 10th place in the Nikon Small World photomicrography contest with a photo of a clam shrimp from Alberta.

According to the news release:  "Gardiner's detailed portrait of a clam shrimp from the Alberta Prairie was recognized in the Nikon Small World Photomicrography Competition. His profile of a five-millimetre-long female with eggs was the only Canadian entry that placed, finishing 10th, in October."   In the news release, Ian expanded on his technique for photographing these tiny crustaceans:  "I give them a small shot of vodka, which kind of keeps them quiet so I can photograph them,"

A New Fairy Shrimp for BC: Eubranchipus intricatus

Male Smoothlip Fairy Shrimp (Eubranchipus intricatus), photo by Ian Gardiner

E-Fauna BC freshwater mollusc editor Ian Gardiner has done it again.  Earlier this month, he discovered a new crayfish species for BC, and now he has discovered another new species for BC--the Smoothlip Fairy Shrimp (Eubranchipus intricatus).  Ian photographed and collected this tiny crustacean from two temporary sloughs near Jaffray BC in the Kootenays.  His find is a first for BC and specimens have been sent to the Royal BC Museum for their collection.

Ian indicates that this species of fairy shrimp is found in temporary pools of low salinity and its range in North America is limited to Alberta, Saskatchewan, Manitoba, Nova Scotia, Montana, Minnesota, Wyoming and Massachusetts.
