Status B
Subject: Animals
Part of speech: Noun, Masculine, Singular
Plural: maelgwn
Definition: Squatina squatina
Notes: Yr 'angel shark' yw'r enw mwyaf cyffredin ar y rhywogaeth hon. SYLWCH: mae'r maelgi (Squatina squatina) yn rhywogaeth sydd wedi'i gwarchod. Serch hynny defnyddir yr enw Saesneg 'monkfish' yn achlysurol hefyd ar gyfer y rhywogaeth a elwir yn fwy cyffredin yn 'anglerfish' neu'n 'angler' (Lophius piscatorius, Cymraeg: cythraul y môr). Oherwydd statws warchodedig Squatina squatina, mae'n bwysig peidio â drysu rhyngddynt.
