    Hammerhead worm

    This is an unidentified species of a land planarian belonging to the genus Bipalium (Tricladida - Geoplanidae).

    Most land planarians are tropical in distribution due to their requirement for hot and humid environments. All are nocturnal in habit and are voracious predators of soft-bodied invertebrates, which are detected via chemical cues and subdued with copious amounts of mucous and an eversible pharynx.

    Spiny orb-weaver: the Long-winged Kite Spider - Gasteracantha versicolor

    Spiny orb-weavers come in a wide variety of shapes and colors. These spiders belong to the genus Gasteracantha within the Araneidae family, and are remarkable for the hard, horny epidermis of their abdomen, which is also armed with two, four, or six prominent spines, varying in length, strength, and direction, and issuing from different points of the margin. The abdomen is also marked on the upperside, and occasionally underneath, with numerous symmetrically disposed cicatricose spots, varying a little in number, size, form, and position.

    Gasteracantha versicolor is one of the about 170 species currently recognized into the genus. It is commonly named Long-winged kite spider and can be found in the tropics and sub-tropics, where it occurs in forests. It has an extensive range, from central, east and southern Africa to Madagascar.

    The female of this species is 8 to 10 mm long, with a large, glossy and brightly colored abdomen. The hardened abdomen has six peripheral spines, with the lateral pair longer and slightly recurved. Males are much smaller, less colorful and lack the thorny abdominal projections.

    Short-beaked echidna 

    The Short-beaked echidna, Tachyglossus aculeatus (Monotrematae - Tachyglossidae), is the most widely distributed endemic Australian mammal, and echidnas from different geographic areas differ so much in appearance that they have been assigned to several subspecies.

    This is the tasmanian subspecies, Tachyglossus aculeatus setosus. They look a lot more cuddly and have a lot more hair than the ones on the Australian mainland that are all spines.

    Echidnas lay shell covered eggs that hatch outside the mother’s body, and although they do not have teats, secrete milk through several pores in the belly.

    Rosy Maple Moth (Dryocampa rubicunda)

    …a beautiful species of Royal Moth (Ceratocampinae) which occurs in Eastern North America. Like other Saturniid moths adult rosy maple moths lack mouthparts and live short lives dedicated solely to breeding. In the north they typically fly from May-August (with one brood) and in the south they fly from April-September (2-3 broods). Rosy maple moth caterpillars are typically known as Green-striped Mapleworms and are commonly seen feeding on maples (Acer spp.), sycamore (Platanus spp.), beech (Fagus spp.) and oaks (Quercus spp.)
