She caught a big one!

Margot Robbie showed off her fishing skills -- and her sexy bikini bod -- during a fun afternoon excursion in Nicaragua.

She posted the pretty pic of herself, modeling a leopard-print two-piece, on Instagram, writing, "Fish are friends not food! #HappyEarthDay."

The "Wolf of Wall Street" star seems to be having a ton of fun in the sun! She shared another sultry snapshot of herself, spending some quiet time in the pool.

In that pic, the brunette beauty is looking away from the camera, sporting a ruffled pink bikini top and a feminine flower in her hair.  

Robbie will soon begin filming her role as Jane to "True Blood's" Alexander Skarsgard, in the upcoming film "Tarzan."

We can't wait to see them hit the big screen together!
