Burrowing Brittle Stars Transport Food Along Arms
California, Indonesia and the Philippines — 2013-2017
Burrowing brittle stars bury themselves in sand or rubble bottoms with two or three legs sticking up. They use the protruding legs to filter feed, then sequentially flex their tube feet to transfer the food particles down along the arms and into their mouths.

Amphipod Attacks Pteraeolidia Eating Its Hydroid Home
Tulamben, Bali, Indonesia — July 2015
Colorful flea-sized amphipods can often be found living on flower-like hydroids on the sandy slopes of the Indo-Pacific. Unfortunately for the amphipods, these hydroids are a favorite food of several nudibranchs. Here, one plucky little amphipod tries in vain to defend his hydroid home.

Peanut Worm Feeds
Tulamben, Bali, Indonesia — February 2014
Peanut worms, also called sipunculans, are a phylum of worms rarely spotted by divers. Most live in shallow water buried under sand, mud, stones or in rocky crevices. To feed, they extend their anterior section, called the introvert, to collect food particles then draw them into the mouth as the introvert is retracted.
Sea Apples Feed
Komodo and Alor, Indonesia — 2014-2020
Sea apples are a brightly colored type of sea cucumber that live primarily in the cooler-water areas of the Indo-Pacific. Watching them feed is equal parts mesmerizing and disturbing.

Palos Verde Peninsula, CA — July 2020
50℉ water and 10 foot visibility didn’t stop our intrepid group from spotting some nice nudibranchs and other tiny critters, and I had another special find with a rarely-seen-around-here Trapania velox at the very end of the last dive.
