The male rhinoceros iguana is under a lot of pressure. Courtship occurs just two weeks a year, and he waits patiently - unlike other species we know - for the female to emerge from her burrow so he can impress her with his strength. You can learn more about this bizarre mating ritual at "Lizards & Snakes: Alive!," where 26 species and more than 60 reptiles with projectile tongues, deadly venom, and unusual camouflage are visiting from five continents. The animals will be hanging out in ponds, tree limbs, rock ledges, and other realistic settings. Today's hours are 9 a.m.-5 p.m. (exhibit runs through April 27). $17, $15 seniors, $14 ages 3-11. Museum of Science, Science Park, Boston. 617-723-2500. mos.org
