These sea stars were washed up on the beach at Fort Myers, Florida, last weekend.

#1

#2

#3 There were some 9-armed sea stars on the beach, but this one has 10 arms!

The first one looks like a Lined Starfish. The second looks like a 9 Armed Starfish, but it has 10 arms. So, that may not be right.

So are #1 and #2 both lined starfish? And do 9-armed starfish sometimes have 10 arms?

Hi morretti,

#3 does indeed to appear to be a nine-armed sea star (Luidia senegalensis), which can uncommonly have 10 arms. It typically is not referred to as a lined starfish.

Yes pictures 1 and 2 are Lined Sea Stars, 3 is Nine Armed Sea Star.
