The feeding methods of invertebrates and vertebrates are very diverse, as feeding techniques can vary depending on the animal as well as the kind of environment it is adapted to, animals also have different feeding techniques to maximise their chances of getting food. This essay looks at the feeding behaviour of carnivores and considers some of the similarities and differences in the feeding strategies of; vertebrates such as the humpback whale (Megaptera novaeangliae) and the African lion (Panthera leo bleyenberghiand) and invertebrates such as the Wolf spider (Pardosa milvina) and the Ant lion (Glenurus gratus).
Although vertebrates and invertebrates are different in many ways, they can both be deadly predators and have both developed a wide range of feeding strategies. African lions (Panthera leo bleyenberghiand) and humpback whales (Megaptera novaeangliae) are active hunters which means they don’t sit and wait for their prey. Similarly Wolf spiders (Pardosa milvina) are sometimes active hunters. “They can be idle predators that wait for prey to pass by, or they can actively hunt their prey”. (Vickers, 2001) Wolf spiders(Pardosa milvina) have many feeding adaptations Ross (2001) found “They tend to hunt by sight and chase”. Just like African lions where Boorer stated (1969) “stalking their prey as any other cat would, and then seeking to surprise it by covering the last few yards in bound” (p. 91). Wolf spiders also tend to work by surprising their prey as “they will search silently for their prey and pounce as soon as it becomes close enough. Ross (2001) also stated “Wolf spiders are named so because of the way in which they pounce on their prey with great speed and strength”. However another feeding strategy wolf spiders ha...

...nt lion takes its pincers and captures the ant. Then it uses a stinger in its pincers to poison the ant and paralyze it”. Just like the ant lion once the Wolf spider has pounced on its prey it then poisons it. “The spider envenoms its prey with fangs, at the same time puncturing the body so it may suck the body fluids out”. (Ross, 2001)

In conclusion this essay shows that many species have adapted many feeding strategies in order for them to survive. Invertebrates and vertebrates may have many similarities and difference in terms of their feeding habits but they both have a variety of amazing feeding behaviours. Some chase and hunt down their prey, others save energy by sitting and waiting, some hunt in groups, whilst others work alone, many have learnt new skills & learnt how to use tools, whilst others have even learnt unique ways to trick or trap their prey.
