Monk seals

By Tamara Cruz Ortega

Monk seals are aquatic mammals and It hasn´t got external ears. You can not turn their hind flippers forward under the body and its skin is covered with hair. The monk seal is named for having a fat ring behind the head. Monk seals live in warm waters and belong to the genus
monachus.

There are three species:

  • The monk seal of the Mediterranean (Monachus Monachus).
  • The monk seal of the tropical Indean (Monachus Tropicalis).
  • The monk seal of Hawaiian (Monachus Schauinslandi).

The monk seal of the Mediterranean is one of the 10 most endangered mammal species inthe world. In Spain, contained in the category “endangered” National Catalogue of Endangered Species.

Today only about 500 copies are distributed between the Mediterranean and Eastern Atlantic
persecution by fishermen, the reduction of coastal fisheries, pollution and habitat destruction.

Nowadays to prevent the hunting of monk seals and the extinction of them we have to reduce the fishing and to pollute and destruct their environment without sea pouring harmful products and preventing them from reaching shore and kill slowly on account of that dozens of monk
seals over the years.

The Tiger

The tiger is native to Asia. Tiger is solitary and territorial animal, that it lives in forest and also in savanna. The tiger is the largest feline in the world. Male tigers have a weight between 100 and 306 kg and 220-330cm in longitude including the tail. The females, much smaller, have a weight of 85 – 167 kg. and a total logitude of 210-275 cm.

Most tigers have an orange coat and stripes varies from dark brownto black. The shape and number of stripes vary according to theirsex (if it is  female the number of stripes is lower).

Nowadays, the biggest enemy of the tiger is the human, to take it fur and bones. Tiger bones have been used in traditional Oriental medicine,although today this practice has been prohibited in China. The illegal hunting to obtain the skin, and habitat destruction have reduced the wild tiger population.

The black panther.

The black panther has got emerald eyes and has an incredible adept.  They are usually in India, South Africa, Java and Malaysia.  They can be in hot climates and not cold but cooler. They have lots of enemies in the jungle like the lions, the tigers, the crocodiles, the pitons, the wild dogs and the mandrilles.

But the most dangerous of all is the human. The humans hunt them because of a sport and then they sell the black panther skin.

Mutualism!

Mutualism is the way two organisms biologically interact where each individual derives a fitness benefit.

It is a subdivision of intraspecific interaction. One specie needs the other but can live without it. Both of them benefit from the other. For example, a buffalo lets the oxpecker put on him to eat the flies and release from them, but the bird also benefit because can eat something that seem to it to be good. Let’s see the video of a enjoyed way:

I have taken the information from the lesson and the first part (the definition) from wikipedia.

Predation

In ecology, predation describes biological interaction where a predator  feeds on its prey. Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the death of its prey and the eventual absorption of the prey’s tissue through consumption. It can often be difficult to separate our various types of feeding behaviors.

The key characteristic of predation however is the predator’s direct impact on the prey population. On the other hand, detritivores simply eat dead organic material arising from the decay of dead individuals and have no direct impact on the “donor” organism.
