Big hunk of it washed ashore after the recent king tides. About 18".
Worn; about 2/3" long.
2nd day of the REGUA tour, and we went to 1000 meters above sea level. Weather did not really bring out that many species, but this species here is quite rare in the region, and probably was the highlight of the day.
Salinas, Rio de Janeiro, Brazil.
Animals are multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. Most animals are motile, meaning they can move spontaneously and independently. All animals must ingest other organisms or their products for sustenance (see Heterotroph).
