Named after a cactus


Large waves during the past week have washed lots of seaweed onto the beaches.  Pictured above is Red Opuntia (Opuntiella californica) — named after prickly pear cactus (Opuntia spp.).  Note the distinctive growth form, with spreading branches of rounded blades.

P.S.  I had no idea — Do you know how many different species of prickly pear cactus can be found in California?  Any guesses?  The answer is: Fifteen!  (There's only one species of Opuntiella in the state.)
