Diving off Lanai at Lighthouse and Shark's Fin Rock

(A) (B) (C) (D)
What these are:
(A)
Me waving to the underwater camera.
(B)
Me and a white tip shark. White tips are reef sharks that mostly come out at night and tend to sleep in caves (with currents) during the day. This one came out due to the efforts of our dive guide.
(C)
A school of Penant Fish, one of the many tropical found at this dive site. These fish are commonly mistaken for Moorish Idol's which have very similar coloration. However, there body shape is somewhat different, especially towards the snout.
(D)
A Porcupine Starfish that one of the dive guides found. This one was at about 50ft, so when I saw it, it was blue-green and looked like a 1ft wide urchin. If you look carefully, you can see the feet.
