LitHub voted my book in their top-10 non-fiction! "The strange creatures of the deep ocean are endlessly fascinating, and Drew Harvell’s fascinating exploration of the depths of their wondrousness is as gripping as you’d hope."

#Nudibranch superpowers! I'm updating the blog on my website with tidepool meanderings, starting with nudibranchs. Here is my Monterey #tidepool favorite, Hopkin's Rose. It uptakes its color from its prey, Rosy Bryozoan.

Loved doing this interview about captive breeding and conservation of #sunflowerstars with the sunflower star aquarist @montereyaq.bsky.social and a chat about my upcoming book, The Ocean's Menagerie.

Grazing by small #herbivores associated with a 29% increase in eelgrass #disease, contributing to huge losses in meadow areas from San Diego to Alaska.Nice story from @cornellcals.bsky.social summarizing our #eelgrass double-header in Ecology; Dr Graham cover photo!

The opalescent nudibranch eats small anemones and hydroids; it uptakes prey's stinging cells for its defense. The Doriopsilla is one of several "lemon #dorids" here, and eats sponges. The long-armed #brittlestar reminds me of this #Blashka model (Ophionereis annulate) made in glass 180 years ago.

Great low tide at #HopkinsMarineStation shared with our Waves of Convergence #Stanford workshop. #Nudibranchs (Hermissenda and Doriopsilla), and Long-arm #brittlestar

#Herbivores facilitate disease spread in #eelgrass. So proud of Team Eelgrass lead by Dr Olivia J Graham. And cool cover photo! esajournals.onlinelibrary.wiley.com/doi/full/10....

In #tidepools today at the #GreatTidePool we also saw 2 different yellow #nudibranchs, Peltodoris and a new one for me, Doriopsilla, both sponge predators. And a brooding anemone with a big baby, and an adorable flat #crab with huge claws. And a Hopkins Rose nudibranch.

Low-tide at #GreatTidePool. #Ricketts and #Steinbeck were right about the richness of #invertebrates here! Lots today starting with a flat crab, a two-spot #octopus, brooding anemone and 4 #nudibranchs.

A day for chitons near the Great Tide Pool with @brookeweigel.bsky.social . Here is a lined chiton and a mossy chiton showing their 8 characteristic plates.

A day for chitons on low tides near Ed Rickett’s Great Tide Pool in Pacific Grove. Here's a huge gumboot chiton chillin' with a bat star and lined and mossy chitons below.

A few of my favorite tidepool shots of 2024 from San Juan Island and Monterey, better late than never for #invertefest!

My #Invertefest holiday attempt at Hopkins Rose watercolor. Like a flamingo, it uptakes color from its prey, a red/pink bryozoan. It was named by Frank Macfarland in 1905 after Timothy Hopkins, patron of Hopkins Marine Lab.

For Invertefest day 1 and celebrating King Tides is my 5 Phylum intertidal cave. How many different Invert groups can you find from this Monterey tidepool cave?

Here's the full moon rising and the very large ochre and another young bloodstar...a lot to see on one fantastic tide series

Full moon rising over Monterey Bay and the Stars are out on a King Tide. Such a brilliant diversity! Bat stars, ochre stars, baby blood stars, and brittle stars! #Marinelife #Invert #lowtide #tidepool #intertidal #seastar

Brittle star (maybe Ophiothrix sp) in tidepools on king-tide near batstar nursery on my spineless meanders. Those tubefeet!
