Purple-faced Langur (Semnopithecus vetulus)

Also known as the purple-faced leaf monkey, the purple-faced langur is a species of Old World Monkey (Cercopithecidae) that is endemic to Sri Lanka. Purple-faced langur typically occur in close canopy forests in Sri Lanka’s mountains and the southwestern part of the country known as the “wet zone”. Purple-faced langur are mainly folivorous  (leaf eating) but are also known to feed on fruits, flower and seeds as well. 

Currently Semnopithecus ventulus is listed as Endangered by the IUCN, as rapid urbanization has led to a significant decrease in their population level.

The Phycodurus eques, or more commonly known as the leafy seadragon, is a marine fish that is found in the waters of Southern Australia. It is known for its long leaf-like protrusions that serve solely as camouflage. As with seahorses, the male is in charge of caring for the eggs, which are usually numbered at around 250.

Wire-crested Thorntail (Discosura popelairii)

…a  rare and striking species of hummingbird which occurs in Colombia, Ecuador, and Peru. Where it inhabits solely inhabits lowland forests, and is not tolerant of secondary habitats. Like most striking plumaged birds wire-crested thorntails are sexually dimorphic with lacking the long “wire” crests and “thorn” tails of males. In typical humming bird fashion wire-crested thorntails feed on nectar from flowers, but will occasionally take insects as well. 

Currently Discosura popelairii is listed as near threatened by the IUCN, as it faces accelerating threats from deforestation in the Amazon Basin.

Blue Club Tunicate - Rhopalaea crassa

Rhopalaea crassa (Enterogona - Diazonidae) is a species of solitary tunicate found in the Central Indo-Pacific Ocean, which inhabits hard substrates in shallow water subject to good water movement.

This sea squirt exhibits an extraordinary ability: its thorax degenerates from time to time and is replaced by a new one. It has been hypothesized that this regeneration process is the intermediate condition between simple ascidians and the formation of colonies.

Woodpecker Tongues
The woodpecker’s tongue can extend 2/3 its body length. Its tongue is covered in sticky saliva and barbs all over with an ear (a hearing mechanism) at the end of it. So it can listen to its prey. It detects sound. The tongue is so long that it fits its tongue in its head by wrapping around its brain and around its eye sockets. It can move its head/beak up to 15-16 times per second as it strikes a tree. This is incredibly fast. It creates immense forces, 250 more times than astronauts are subjected to. It is 1,000 G’s. The woodpecker has cartilage around the brain that keeps it from shattering.
