Tenrec

Lowland Streaked Tenrec (Hemicentetes semispinosus)

…is a small species of tenrec found throughout eastern and northern Madagascar. Like other tenrec species the lowland streaked tenrec is mostly nocturnal hunting for earthworms and insects under the cover of darkness. When threatened this tenrec can erect its quills forward and will attempt to drive them into its attacker. When foraging the lowland streaked tenrec is often found in small family groups that communicate with each other by vibrating the spines on their middle of their backs. They are the only recorded mammal to communicate via this method known as stridulation.

Lowland Streaked Tenrec (Hemicentetes semispinosus)

… inhabits rainforests on the east side of the island of Madagascar. It forages amongst the leaf litter for earthworms and other soft-bodied invertebrates, using its long snout to delve into small spaces.

During the winter (May to October), tenrecs can drop their body temperature to nearly that of the surroundings, but still remain active. This conserves energy, but in the coldest weather they must hibernate. Nesting in burrows 1.5 m long and 15 cm deep near a stream or water body, the lowland streaked tenrec covers the burrow entrance with leaves and often creates a latrine site nearby…

Lowland streaked tenrec (Hemicentetes semispinosus)

The lowland streaked tenrec is a small tenrec found in Madagascar. It is found in tropical lowland rain forests. The head and body are 4.8-6.5 inches in length. It is active during day and night, feeding primarily upon earthworms, but also on insects. The streaked tenrec lives in long, shallow burrows which are usually occupied by family groups. If threatened by a predator, a streaked tenrec erects the barbed quills on its back and on the crest around its head, pointing them completely forward, and drives them in to the attacker’s nose or paws with body and head movements. The nonbarbed quills are clustered in the middle of the back, and produce a faint chattering sound when vibrated, and are used to communicate within family groups.

Three Wee Tenrec Tykes Born at Paradise Wildlife Park

The UK’s Paradise Wildlife Park announced the birth three Tenrec babies! Born to mom Maisy on the 10th of July, these prickly little balls look a lot like Hedgehogs… but are, in fact, completely unrelated! They have simply evolved the same method of defense, which is to roll up in a ball so that predators are met with only their outer coat of prickles. This is called convergent evolution, a process by which organisms not closely related independently evolve to have similar traits as a result of having to adapt to similar environments or ecological niches.

       Evolution Of A Shad by knockabiller

This one kind of blows my mind, it is an extraordinary set of mutations, both inventive and brutal. I almost find it difficult to look at the ones in the middle; such extreme bodily changes must be greatly painful to go through. I feel greater poignancy of Shadow’s combined genetics now then I did after playing his game.

I like the start the most, the symbol on the egg, Shadow as a Death Leech, infant looking like Black Doom combined with Dark Run Speed (also known as Shadow Chao). The Eclipse feet are also a nice touch.

The thought of Shadow’s biological parents giving him up to be experimented on is also very cruel in a sad but compelling way, oh the feels…

Lesser Hedgehog Tenrec (Echinops telfairi)

…Despite its common name this Madagascan mammal is in no way related to insectivores and is more closely related to mammals from the age of dinosaurs. Like most tenrecs this species is only found on the island of Madagascar, this species in particular is only found in the southwestern region of the island. Like a hedgehog the lesser hedgehog tenrec is an insectivore and hunts at night for insects and other invertebrates. During the day they can be found resting either on the ground or in a tree as tenrecs unlike hedgehogs are proficient climbers.

The Lowland streaked tenrec, Hemicentetes semispinosus (Afrosoricida - Tenrecidae), is one of the two extant species in the genus, both are found only on Madagascar [1].

Tenrecs look like a cross between a shrew and a hedgehog, with long, pointed snouts and spines amongst their fur. Hemicentetes semispinosus is a medium-sized slender tenrec (16-19cm length). It is blackish-brown with yellowish stripes running the length of the body and a yellowish band running from the crown to the tip of the snout. It has detachable, barbed spines which are most numerous on the crown. The underside is chestnut-brown with soft hairs [2]
