Predators. The Black Mamba doesn’t have to worry too much about predators out there in the wild. The Mongoose though is one that is does have to reckon with. They aren’t going to be bullied into running off. They are most likely to find the eggs that have been deposited or feed on the young snakes that haven’t been out of the eggs for long.
Crocodile Threats. We often spend so much time thinking of the crocodile as a predator that we fail to see what may be eating it. The smaller a crocodile is the more likely it is to become a meal. In fact, only about 2% of the young that hatch end up making it to full maturity.
Komodo dragons are the top predators in their range, and adults do not suffer predation by any species. Young Komodo dragons sometimes fall prey to predatory mammals, birds and other Komodo dragons. Juveniles live in trees as protection until they are large enough to defend themselves.
Lions do not have many natural predators; humans, other lions and hyenas are sometimes known to kill lions. The lion is referred to as the king of the jungle, but hyenas will sometimes kill them when they are injured and the hyena is extremely hungry.
The large crocodiles are apex predators and, as adults, do not have regular predators. There are certainly examples of other predators killing crocodiles, and even hunting them. You can find video footage of the largest three big cats -- tigers, lions, and jaguars -- all attacking crocodiles.
The Piranha is one of the most efficient predators on the face of the earth. Granted it is not a large animal, with most only reaching about 5 1/2 to 10 inches (14 – 26 cm), but it is known world wide for its ferocious nature. They have razor sharp teeth and are opportunistic carnivores.
Once the tarantula is paralyzed from the wasp venom, the tarantula hawk wasp drags it into a lair, or sometimes even the tarantula’s own burrow. The wasp lays an egg on the spider and then seals up the burrow. When the wasp maggot hatches, it eats the tarantula and then emerges from the burrow as a fully mature wasp.
