What does it appear to be? The marine iguana is a big, raveled wanting lizard. Fully grown males might be 1.three m lengthy and weigh as a lot as 1.5 kg. They are usually black or gray. Color may also fluctuate relying on the island on which they're discovered. In some places, the adults are brick crimson and black, whereas somewhere else they're crimson and darkish inexperienced, however primarily throughout the breeding season. The tail could be very lengthy, and the limbs are nicely developed with lengthy, curved claws. Along their again, the lizards even have a crest of spines giving them a fierce, dragonlike look.
Where does it dwell? The marine iguana is simply discovered on a number of the islands that make up the Galapagos archipelago. They are usually discovered on the rocky shoreline however often might be seen in areas of marshland and mangrove swamp.
During his expedition aboard the Beagle, Charles Darwin noticed and studied many creatures unknown to Europeans. The Galapagos had been a wealthy looking floor for his gathering forays, and on the wave-crushed shores of a number of the extra barren islands, he took notice of a peculiar lizard basking on the black volcanic rock. In Darwin’s eyes, this lizard—the marine iguana—was removed from being a looker. The younger naturalist described it as a “disgusting, clumsy lizard.” It’s honest to say the marine iguana shouldn't be the prettiest animal, however what it lacks in appears it greater than makes up for in character.
Large teams of these lizards bask on the wave lashed shore, their spiky our bodies nearly mixing into with rugged volcanic rock. Like all lizards, marine iguanas rely upon the solar for his or her heat. Before they'll seek for food, they need to bask within the solar’s rays till their physique temperature has risen sufficiently. With their muscle mass properly warmed, they'll set about foraging.

They cling to the rocks with their sharp claws and graze the low-rising seaweed. Although the Galapagos Islands straddle the equator, the water ﬂ owing round them is cool—the results of upwellings from the ocean depths. It doesn’t take too lengthy till the marine iguana begins feeling the chilliness, and in a state of chilly fatigue, it should floor and haul itself out onto the rocks.
This isn't any imply feat for a chilly-blooded animal. Out on the rocks, the iguana returns sluggishly to its territory and sprawls out beneath the warming solar. During its subaquatic forays, the iguana swallows various salt water with its food, and to stop any sick results, it should do away with this extra salt. It does this with using particular glands, the merchandise of that are sneezed from the nostrils. Following stint within the solar, the iguana might make one other foray into the water to get at its favourite seaweed.
These day by day forages for food and lengthy intervals of sunbathing are how the marine iguana spends its time. This absolutely makes it one of the devoted seashore bums within the animal kingdom.
