Star-nosed Mole

star-nosed-moleTHIS weird and wonderful creature is the star-nosed mole (Condylura cristata), a small, semi-aquatic mammal which inhabits the low wetlands of eastern North America. Like other moles, it ekes out an existence in a network of narrow underground tunnels, and digs shallow surface tunnels where it forages for insects, worms and molluscs. Living as it does in almost complete darkness, the star-nosed mole has poorly developed eyes, and is virtually blind. Instead, it relies heavily on its remarkable star-shaped nose. This organ enables the star-nosed mole to decide whether something is edible with astonishing speed - in fact, it recently entered the Guinness Book of Records as the world’s fastest forager - and also to sniff out food underwater.

Spinybacked Orbweaver – a.k.a. Gasteracantha cancriformis

spinybacked-orbweaver-e28093-aka-gasteracantha-cancriformisscientific name: Gasteracantha cancriformis (Linnaeus) (Arachnida: Araneae: Araneidae)

Introduction

One of the more colorful spiders in Florida is the spinybacked orbweaver, Gasteracantha cancriformis (Linnaeus) 1767. Although not as large as some of the other common orb weavers (e.g.; Argiope, Levi 1968; Neoscona, Edwards 1984), the combination of color, shape, and web characteristics make G. cancriformis one of the most conspicuous of spiders.

The Invisible Glasswing Butterfly

the-invisible-glasswing-butterflyA butterfly with transparent wings? Surely not. Yet there is a species that exhibits this trait. Take a close look at the incredible Glasswing, an enchanting species that confounds science.

Greta oto may sound like the name of a silent movie star from Eastern Europe but is, in fact, the scientific name for one of the most exquisite – and little known – species of butterfly on the planet. This butterfly’s claim to fame is that its wings, spanning up to six centimeters, are almost completely transparent. That’s right, you can see just about right through them. Continue Reading »

Hyrax – Creature that is Very Different from Other Animals

hyrax-e28093-creature-that-is-very-different-from-other-animalsPhysical Characteristics

The hyrax is so unlike other animals that it is placed in a separate order (Hyracoidea) by itself. It is said to be the elephant’s nearest living relative. This is true to a certain extent, but misleading since the relationship stems from a remote ancestor common to hyraxes, sea cows (dugongs and manatees) and elephants. These three are unlike other mammals, but they share various if disproportionate physiological similarities in teeth, leg and foot bones, testes (that do not descend into a scrotum) and other more obscure details.
