subchelate การใช้

• The animal's chelae ( claws ), although the last segment may be able to grip against an extension of the previous segment in some cases ( subchelate ).
• "Crangon " is classified in the family Crangonidae, and shares the family's characteristic subchelate first pereiopods ( where the movable finger closes onto a short projection, rather than a similarly sized fixed finger ) and short rostrum.
• Reef lobsters are distinguished from clawed lobsters ( family Nephropidae ) by having full chelae ( " claws " ) only on the first pair of pereiopods, the second and third pairs being only subchelate ( where the last segment of the appendage can press against a short projection from the penultimate one ).
