noun
Japanese eagle ray
A species of eagle ray (Myliobatis tobijei) found in Japanese waters. The name is usually written in kana.
トビエイは海底近くを泳ぐエイの一種です。
The Japanese eagle ray is a type of ray that swims near the sea floor.
The name likely combines 鳶 (tobi, 'black kite', a bird of prey) with エイ (ei, 'ray'), perhaps from a perceived resemblance. The exact origin is uncertain.
