What are solenodons?

Do you know what are solenodons? Solenodons are curious rat-sized creatures with long snouts. They were once found in North America but the only survivors of this ancient group are found on two islands of the West Indies, one species on Cuba and another on Hiti.

What are solenodons

Solenodons are members of a primitive group of mammals called insectivores. These were the first placental mammals and in general the representatives we know today are small creatures (shrew-like, mole-like or hedgehog-like) which feed on a variety of invertebrates.

Solenodeons are shy creatures, sleeping during the day and appearing at night to feed. They run clumsily on their toes in a zig-zag course and if chased are likely to trip over.

What are solenodons: Solenodons have managed to survive on two West Indian islands. Competition from man and introduced higher mammals (dogs and cats for example) has made them rare animals and they seem doomed to extinction.

Which mammals really fly?

True flapping flight, almost as proficient as that of the birds, has been achieved by only one group of mammals, the bats. Bats probably evolved from a group of early insectivores that fed by leaping from the branches of trees to catch passing insects.

It is interesting that bats fly by cupping their wings in front of the body and dragging this air behind them, rather than flapping their wings up and down.

Bats can be arranged into two large groups: fruit-eaters and insect-eaters. In general the fruit-eaters are large, can see well and fly n dim light. Insect-eaters are large, can see well and fly in dim light. Insect-eaters are usually smaller, have poor eyesight and have developed a good system of echo-location to enable them to fly in pitch blackness.

By sending out series of ultrasonic squeaks and listening for the returning echoes with very efficient ears, the bats can navigate their way around obstacles and catch their insect prey in darkness.

In many insect-eating bats them nose in obscured by highly folded flaps of skin. It is thought that this ‘nose-leaf’ concentrates the high-pitched squeaks emitted from the bats’ nostrils, and even possibly directs them.

Which mole has a star on its nose?

Moles, also members of the insectivore group of primitive mammals, are burrowing creatures completely adapted for an underground file. A mole on the surface can hardly move forwards at all but once burrowing it quickly disappears from sight.

Short but powerful clawed limbs stick out side-ways and shovel the soil behind the mole as it tunnels for-wards. Moles cannot see very well, some are blind, but they have very highly developed senses of hearing and touch.

To perfect its sense of touch, the North American Star-nosed Mole has remarkable bunch of twenty- tentacles on the end of its nose. These are highly sensitive and mobile and are brought into use when the mole is searching for food, usually under water.

The hearing of insect-eating bats is well developed. The Mouse-eared Bat is appropriately named. The fruit bats feed on dates, figs and bananas.
