Why do female lions hunt instead of male lions?

The African Lion (Panthera leo) is a carnivorous – meat eating – mammal. It kills and eats ungulate mammals (animals with hooves), such as zebra, buffalo, giraffe, wildebeest, warthog, gazelle, and impala. 

Lions live in a pride, which is a group of family members consisting of 10-12 females and their male and female children, called cubs, with one to three dominant males. When male cubs grow up, they become solitary until they form their own pride.

Decorator Crab

The Decorator Crab, or Collector Crab, is a marine saltwater crustacean in the Majoidea super-family with several different species. 

The Decorator Crab is difficult to see in its natural habitat in tropical reefs and lagoons because it covers itself with aquatic plants and materials from its environment.

About 75% of crabs in the Majoidea super-family decorate themselves for camouflage. Some cover themselves completely and some cover themselves a little bit.

Macleay’s Spectre Stick Insect Baby

The Paris Zoo is nurturing baby Macleay’s Spectre Stick Insects born in March 2022. They are in a separate terrarium to keep them safe. The baby Stick Insect is called a nymph.

The female Macleay’s Spectre Stick Insect breeds parthenogenically, meaning that she lays eggs that hatch without being fertilized. The female lays 100-1,200 eggs on the ground or on a plant. The eggs hatch after about 4 months into nymphs, which look like ants. The nymphs eat plants and grow into an adult stick insect.

The Stick Grasshopper (Paraproscopia riedei) is an insect in the Proscopiidae family. It is also known as the Locust Phasmid, the Horsehead Grasshopper, and the Jumping Stick. It is not a stick insect phasmid – it is a stick locust, a proscopiid.

The Stick Grasshopper has a green to brown, cylindrical, and elongated body. It has a conical head with large eyes. It has short antennae. The wings are extremely short or absent. It cannot fly and protects itself by camouflaging itself like a stick. It has six long thin legs. It has strong hind (back) legs and it can jump large distances.

Fallacy: a chameleon changes colour to camouflage itself

Is it true that a chameleon changes colour to camouflage itself? This might be a fallacy – a fallacy means that it is not true.

The Chameleon is a reptile in the Chamaeleonidae family of lizards. It is arboreal because it lives in trees. The Chameleon is native to Africa, Madagascar, southern Europe, and southern Asia. It prefers to live in warm regions, such as rain forests and deserts. 

I have written in this website that the Chameleon can be a variety of colours, and “it can change colour to match its environment – this is called camouflage.” But it might be incorrect to say this.

Panther Chameleon

The Panther Chameleon (Furcifer pardalis) is a reptile in the Chamaeleonidae family. 

The male Panther Chameleon can vary in colour from blue to red, green, orange. The female is usually tan and brown with a bit of pink or orange. It has distinctive eyes, with a pin-hole where the pupil is located. Its eyes, with good eyesight, can rotate independently, giving the Panther Chameleon 360 degrees of vision (all around it). It has a very long tongue with a suction-capped tip to catch insects.

It has five toes on each foot, but some are fused together so it looks like it only has two toes on each foot: two together and three together. Its feet act like tongs and can grip branches. Each toe has a sharp claw.

Similarities and Differences in Tiger Stripes: Amur, Bengal, and Sumatran Tigers

What is the difference in tiger stripes between tiger sub-species: Amur Tiger (Panthera tigris tigris), Bengal Tiger (Panthera tigris tigris), and the Sumatran Tiger (Panthera tigris sondaica)? They all belong to the Felidae family and Panthera genus.

As a form of camouflage, tigers have stripes – not to confuse their predators but to hide from their prey. Tigers like to sneak up close to their prey, hide in tall grass and trees, then pounce on their prey.

Their form of camouflage is called disruptive camouflage because the stripes are broken – short, irregular stripes.

Changing colour for winter

What animals change colour for winter?

Many animals, especially mammals, hibernate (sleep) in winter. Some animals lie dormant (similar to sleep, but lie still). Other animals, such as butterflies and moths and other insects, turn into cocoons and chrysalises in winter, waiting to emerge as adults in spring. Other animals grow their winter fur to keep them warm.

But some animals change colour to camouflage into their autumn and winter environment – brown among dry leaves and leaf litter, white in snowfields, and grey in clouded habitats.
