A girl is seen wearing a shirt over her bathingsuit

A few male characters are shown shirtless.

At one point Sandy is reading a Playboy and a scantily dressed woman is on the cover. We never see any pics on the inside.

Sandy vomits from being seasick (heard, not seen), we later see some vomit on his shirt.

A man shoots a mother dolphin, and another young dolphin takes her to the surface for air, but she is shot a few more times and dies (there's no blood, but this entire sequence could easily disturb people).

A hammerhead attacks and kills a seagull, which we briefly see in its mouth. Afterwards blood is shown coming from the shark's mouth. The same shark later nearly attacks Sandy.

Sandy runs into the bathroom and we hear him vomit from smoking a cigar.

Sandy is nearly stabbed in the head with a fishing spear (but Flipper saves him).

Some mild profanities including ass, h-ll and d-mn. Oh My God is also used a few times. Sandy makes the slang reference "bait my butt".

Brief alcohol use. Porter smokes cigars and forces Sandy to smoke one as a life lesson.

Several close encounters mainly involving Sandy (in one scene, he is nearly attacked by a shark, in another, he is nearly impaled through the face with a fishing spear).
