yellow guitarfish
A species of guitarfish (Rhinobatos schlegelii) found in Japanese waters. The name is usually written in katakana.
I saw a yellow guitarfish at the aquarium.
Katakana spelling is common for this fish name; usually written in kana.
Kanji spelling exists but is rarely used; learners will mostly encounter the katakana form.
The name likely derives from the fish's shape resembling a 坂田 (sloped rice paddy) and 鮫 (shark), but the exact origin is uncertain.
