モロキニ・クレーターではどのような魚が見られますか？

モロキニクレーターでは、シュノーケリングをすると、タイガーフィッシュ、チョウチョウウオ、ブダイ、ヤガラ、ニザダイ（縞模様）、カワハギ、その他の色鮮やかなサンゴ礁の魚によく出会えます。ここは、透き通った水と多様なサンゴ礁の魚が見られる、マウイ島で最も優れた場所の一つです。.

熱帯魚を見るのに一番簡単なマウイ島のシュノーケルスポットはどこですか？

There isn’t one easiest spot every day. Ulua Beach has a sandy entry and nearby reef that can appeal to experienced ocean swimmers when the water is calm and clear, but there’s no lifeguard. Choose your location around current conditions and your swimming ability, not just how close the fish are to shore.

初心者でもマウイ島で岸から熱帯魚を見ることはできますか？

Yes, if you’re new to snorkeling but already an experienced ocean swimmer. Calm, clear conditions and an entry you can comfortably manage are essential. Snorkel with a buddy, and remember that staying near shore or using flotation doesn’t replace swimming ability. If you’re not ready for the ocean, Maui Ocean Center offers another way to enjoy Hawaiʻi’s reef fish.

ハワイ州の魚は何ですか？

ハワイ州の魚は、リーフ・トリガーフィッシュとも呼ばれる「フムフムヌクヌクアプアア」です。ハワイで最もよく知られたリーフフィッシュの一つであり、マウイ島でシュノーケリングをしながら探すのが楽しい魚です。.

マウイ島では、ウミガメにどのくらい近づけますか？

ハワイのマウイ島では、海ガメから水上・陸上ともに最低10フィート（約3メートル）離れてください。絶対に触ったり、追いかけたり、餌をあげたり、乗ったり、進路を妨げたりしないでください。.
