Canarium maculatum (Sowerby, 1842); Tanguissan Beach, Guam, USA; Photo Bob Abela

  • "I found this little guy (with another) while diving off Tanguissan Beach (May 2018). It was at about 40 ft, exposed, on the reef and partially covered by a thin layer of sand. While not a rare, I've only encountered them sporadically on Guam. The photograph is taken from my small aquarium. I haven't measured the shell but it's ~15mm."

Bob Abela on Canarium microurceus from Guam:

  • "The shell is about 10mm. A common species on Guam. I placed a few in the aquarium to feed a small Conus legatus."
  • "They may be found on the reef or in sand, as here, ~35 ft. Agat Bay, Guam; 28 July 2007

Sinustrombus sinuatus x taurus; hybrid form; Guam Island, Mariana Islands, Micronesia, USA, North Pacific Ocean; Photo Bob Abela; Coll. Fred Schroeder

Report about S. sinuatus x taurus hybrid form from Guam by Bob Abela:

  • "I believe the specimen was collected from Hospital Point where an established population of S. taurus exists. S. sinuatus, by all observations, is much more restricted on Guam. A known S. sinuatus population exists just inside the Glass Breakwater (Apra Harbor) and is generally not associated to Hospital Point. I can only speculate that a veliger of S. sinuatus settled on S. taurus "grounds" and hybridized for lack of a better mate."
