The blue whale is the largest mammal species to have ever existed on Earth. Before the whale hunting era started, these creatures could be spotted anywhere in the ocean due to their abundance. At one time in history, there were more than 200,000 blue whales in the world's oceans; now, there are less than 15,000 left. So why are these enormous species on the brink of extinction? It is evident that due to their size, no other creature in the ocean can aim them as their prey. Therefore, the only possible species that can cause any damage to them are humans.

A large chunk of blue whales were killed in the year 1931 by the Soviet Union; 29,649 to be exact. The International Whaling Commission (IWC) declared blue whales as protected animals by the year 1966. However, the Soviet Union continued to whale in the Antarctic Ocean which had an ultimate result of their population immensely decreasing.

Blue whales do not pose any threat to humans. In fact, these poor creatures are victims of their actions which has caused them to be included on the world's endangered animals list. Unfortunately, they are tortured by heavy sea traffic, often getting running over huge ships as they inhabit surface water. Another factor that does not make their population increase is their reproducing rate. A female blue whale reproduces once every two years. It does not help their species range get any larger, thus the IWC has taken many steps to help protect their future. It as our duty as well by doing our part to help any endangered species that exist today (5).

Crocodiles use two strategies to attack their prey. They either sit and wait or they actively hunt. Juveniles position themselves with all four feet on the bottom in shallow water and then wait for their prey to come close enough to where they can grasp them. Crocodiles sense that potential prey is nearby by utilizing their large sensory pits along the sides of their jaws. Larger crocodiles usually remain underwater in the bank or in the water in the bank until they sense their prey. Once they detect it, they head towards its way and submerge in the water till they reach their dinner. The crocodile then emerges its head and if their prey is within striking distance, it will lunge till it comes in its grasp and then slam their paws shut.

Small prey tend to be crushed and swallowed right away. Larger prey are kept in possession of the paws till all movement stops and then are thrown off balance so they can be dragged into deeper water and drowned.
After that, if the prey is too large then they thrash and roll it to dismember it into smaller pieces so they can easily eat their meal (4). 

The bee orchid is a species of orchid originating from Israel that has made a cool adaptation. It is the only species in its genus (Ophrys) that self pollinates. It produces a scent that mimics the scent of the female bee. Not only that, the lip acts as a decoy to make it look like a female bee, the ultimate result is the male bee confusing it as a female bird. After it lands on that, pollination occurs (1).
