Is it a good Haiku example (a frantic spider)?

Hi can you tell me if this is a good haiku?

a frantic spider
scuttles across the sand
Angry waves claim it

It's a good poem and has a solid theme, but you don't have enough syllables in the middle. It's only 6 - you need 7.

It is excellent... very, very good stuff. But you are missing a syllable in that second line. Rework it! I really like the last line.

I always remember this haiku for some reason: Suna hama ni/ ashi ato nagaki/ haru hi kana

It means "A summer day/ a long nine of footprints/ on a sandy beach

I may be getting it a little wrong. Anyway, it is great, like yours, because it shows a scene the suchness of which you can appreciate in a moment of stillness.

Wow.. I really like that last line the more I look at it. You are great... Angry waves claim it.... that is perfect.
