A brinicle is a long, vertical tube of ice formed beneath the sea. It is known as the icicle of death because it destroys everything it comes in contact with. It’s so cold that it causes the surrounding seawater to freeze around it. The spreading ice kills creatures such as sea urchins and starfishes. (Source)
Formerly considered a subspecies of Phyllomedusa burmeisteri, in 2006 Phyllomedusa bahiana (Hylidae) was elevated to full species status on the basis of differences in vocalizations and tadpole morphology.
This species shows a defensive strategy named shrinking behavior, in which the frog adopts a posture with the dorsum arched and the four limbs contracted bent close to the body, remains motionless, generally with the eyes closed or partially closed.
Phyllomedusa bahiana is endemic to Brazil, specifically, from the state of Bahia.

Metatrichia vesparium is a curious and striking species of Myxomycetes, distinctive by the multiple heads developed from a single stem. The fruiting bodies (sporangia) are 1.0 - 1.5 mm long, with rounded top, dark red, red-brown (rusty red), fading to dark color, shining. Stalks are usually fused, with clusters of sporangia erect on the apex, brownish red or darker.
This species is cosmopolitan and can be found on rotten and very moist hard wood. It is reported from Europe, North and South America, Australia, New Zealand, USA, China, Japan, and Taiwan.
