Mesoplodon whales signify one of many least studied teams of mammals, as evidenced by the truth that three new species have been recognized within the final 30 years. The newest of those species, the Ramari beaked whale (M.eueu), was described to science final 12 months.
All beaked whales are likely to have spindle-shaped our bodies and small dorsal fins, making the species troublesome to inform aside within the subject. Additionally, since they’re usually present in the identical areas and feed at related depths, they’re thought to compete with one another for a similar prey: deep-sea squid and small fish. Intently associated species usually show completely different feeding methods, reflecting the evolutionary drive to optimize foraging efficiency and decrease interspecific competitors. Nonetheless, this doesn’t seem like the case amongst this group of intently associated beaked whales.
