Okay, so you're wondering why we don't see bones disappearing everywhere, right? Well, think of it like this: bones are tough cookies! They're made of minerals, like calcium, which are hard to break down. While some creatures, like those deep-sea worms and snails, have special tools or stomachs to dissolve and eat bones, most animals don't. It's like trying to eat a rock – not very appetizing or easy! So, while some bones do get eaten, it's not enough to make all the bones vanish. The rest just stick around and break down very slowly over time.

Oceanographer

As an oceanographer, my perspective is rooted in the fluid dynamics of the marine environment. While biological processes like scavenging are certainly at play, the fate of bones on the seafloor is more complex than simple consumption. Consider the interplay of currents and salinity gradients. Bones, primarily composed of calcium phosphate, are subject to dissolution, particularly in areas with lower pH or higher CO2 concentrations. The rate of dissolution is also influenced by water flow; faster currents can accelerate the process by constantly exposing fresh bone surfaces to the surrounding water. Furthermore, the presence of a bone alters the local fluid dynamics, creating micro-environments that can either enhance or inhibit microbial activity, which also contributes to bone degradation. Ultimately, whether "all" bones are consumed depends on a delicate balance between biological activity, chemical dissolution, and the physical forces exerted by ocean currents. Some bones may indeed be completely broken down by organisms, while others may persist for extended periods, becoming integrated into the sediment or serving as substrates for unique benthic communities.

Skeptic

The assertion that "a lot of bones get exposed every day" requires quantification. How many bones are we talking about, and what is the rate of exposure relative to the rate of consumption or decomposition? Without concrete data, this claim remains unsubstantiated. Furthermore, while certain organisms are known to consume bone, the efficiency and scale of this consumption in relation to the total number of exposed bones is unclear. Factors such as bone density, environmental conditions, and the presence of competing organisms would all influence the rate of bone degradation. Therefore, the question of whether "other critters can eat all of them" cannot be answered definitively without further evidence.

Wildlife Biologist

As a wildlife biologist, I can tell you that while many organisms contribute to bone decomposition, the complete consumption of all exposed bones is unlikely. Marine environments, as you mentioned, have specialized organisms like Osedax worms that thrive on bone lipids. Terrestrial environments have their own scavengers and decomposers, including rodents, insects, and fungi, that can break down bone material over time. However, the rate of bone decomposition varies significantly depending on environmental factors such as temperature, humidity, and soil acidity. In certain conditions, bones can persist for extended periods, becoming fossilized or remaining as skeletal remains. The sheer volume of bones exposed daily, coupled with varying decomposition rates, suggests that not all bones are entirely consumed by other critters.
