Gain a greater appreciation for New York City’s favorite bivalve, the Eastern oyster hosted by Hudson River Park’s River Project. Oysters are filter feeders and thus an important part of the ecosystem as they clean the water, making it more habitable for other species. The “Shell-ebrate Oysters” event delves into the history of mollusks on the city’s shores — before there were hot-dog stands and food carts, the city was filled with oyster stands — and how scientists monitor their growth in the park’s 400-acre Estuarine Sanctuary.
When 2 p.m.

View the French artist Pierre Huyghe’s “mental image” artworks in the online show “Of Ideal” at Hauser & Wirth gallery. To produce these pieces, Mr. Huyghe used a neural network to construct images from M.R.I. scans of subjects who were instructed to think about situations from their past. The results are uncanny, metamorphosing renderings of human memory. The exhibition will remain online through the end of the year.
