Echidna - Kangaroo Island, Australia "Echidnas are small, solitary mammals covered with coarse hair and spines. Superficially, they resemble the anteaters of South America and other spiny mammals such as hedgehogs and porcupines. They have elongated and slender snouts which function as both mouth and nose. Like the platypus, they are equipped with electrosensors, but while the platypus has 40,000 electroreceptors on its bill, the long-billed echidna has only 2,000, and the short-billed echidna, which lives in a drier environment, has no more than 400 located at the tip of its snout. They have very short, strong limbs with large claws, and are powerful diggers. Echidnas have tiny mouths and toothless jaws. The echidna feeds by tearing open soft logs, anthills and the like, and using its long, sticky tongue, which protrudes from its snout, to collect prey" "Echidnas and the platypus are the only egg-laying mammals, known as monotremes. The female lays a single soft-shelled, leathery egg 22 days after mating, and deposits it directly into her pouch. Hatching takes place after 10 days; the young echidna then sucks milk from the pores of the two milk patches (monotremes have no nipples) and remains in the pouch for 45 to 55 days, at which time it starts to develop spines. The mother digs a nursery burrow and deposits the young, returning every five days to suckle it until it is weaned at seven months." en.wikipedia.org/wiki/Echidna AIMG_6463

A male green iguana suns himself on a roof. Green Iguanas, the largest lizards in Costa Rica, are normally green but males can turn orange in breeding season to impress the ladies. They prefer to perch on trees above water. If danger approaches they make their escape by diving into the water below. They normally are arboreal with the female climbing to the ground only to lay eggs. AxMG_1951

This fellow must have jumped into the water beside the tree and now is faced with the daunting task of climing back up to his high perch. AxMG_1932

Green Iguanas, the largest lizards in Costa Rica, are normally green but males can turn orange in breeding season to impress the ladies. They prefer to perch on trees above water. If danger approaches they make their escape by diving into the water below. They normally are arboreal with the female climbing to the ground only to lay eggs. They certainly are a lot easier to photograph than are birds. Although they are found near the top of a tree, they like to be exposed to the sun so visibility is generally better. In addition, they like to remain very still and in one place. AxMG_1949
