Pacific Sand Crab digging into sand

The Pacific Sand Crab (Emerita analoga) is one of the delightful creatures you can find in the surf of beaches along the Pacific Coast of North and South America. These small (up to 1.5 inches / 3.8 cm) crustaceans are a delight for kids and adults to find and observe. As waves lap the beach, the crabs will swim into the water, and then burrow back into the sand as the water recedes. Here is a video showing how the sand crab can bury itself in less than two seconds:

I posted this sand crab video on twitter, and received an interesting response from biologist Zen Faulkes. He published several papers on his experiments investigating the neurobiology and mechanics of how sand crabs dig (1997a, 1997b, 1998).

Elephant Seals at Año Nuevo

These two male Northern Elephant Seals fought with one another on the beach at Año Nuevo on Christmas Eve 2017. Eventually one male backed off and moved away into the ocean.

An introduced planarian in Ohio

In late May 2018, I came across this planarian among the leaves on the forest floor in Cuyahoga County, Ohio. Planarians are part of the group of animals known as Platyhelmintes. Although planarians look a bit like earthworms, they are only distantly related to earthworms and other members of the Annelida. Interestingly, there are many planarians that hunt and eat earthworms.

Although, I knew it was a planarian, I did not know that they could be found in Ohio. Some investigation on my own, and helpful information from contributors on iNaturalist indicated that this was probably a Wandering Broadhead Planarian (Bipalium adventitium). These are an introduced species here in Ohio. If you come across them in Ohio or other parts of the midwest, I would be interested in hearing about it and seeing photos.

A buck jogs past me in my neighborhood.

A male whitetail deer jogged right by me while I was standing in my driveway in Shaker Heights, Ohio. Apparently, two does ran by just a minute or two earlier, but I didn’t see them. This buck was in hot pursuit. He came close enough that I could have touched him, but he was obviously focused on following the does. The video was taken in mid-November, 2017.

Fuzzy white Beech Blight Aphids doing their waggling dance

Beech Blight Aphids (Grylloprociphilus imbricator) will gather in large groups to feed on the sap of beech trees. They have a distinctive “dance” to deter predators. When disturbed, they wave their abdomens and waxy white filaments. These photos and videos were taken in Cuyahoga County, Ohio.
