Otter
When examining the criterion of speed, one must first establish the parameters of measurement. The otter, when motivated by either predatory instinct or playful impulse, can achieve swimming velocities of up to 12 kilometres per hour. This figure, whilst unremarkable in the context of motorised watercraft, represents a triumph of biological engineering when one considers the otter's relatively compact frame and the considerable drag coefficient of its famously luxuriant fur.
The European Otter Velocity Study of 2021 recorded a particularly athletic specimen reaching 14.3 km/h whilst pursuing a trout in the River Severn, though this outlier has been attributed to exceptional motivation rather than superior physiology. Average sustained speeds during typical foraging behaviour hover closer to 8 km/h, with brief acceleration bursts punctuating longer periods of what researchers describe as contemplative floating.
It should be noted that otter speed, whilst modest in absolute terms, is achieved without any external power source, infrastructure requirement, or monthly subscription fee. The otter generates all necessary propulsion through its own muscular effort, a feat that WiFi, for all its electromagnetic sophistication, cannot remotely approach.
WiFi
WiFi's approach to speed operates in an entirely different domain of measurement. Modern WiFi 6 (802.11ax) technology can achieve theoretical maximum throughput of 9.6 Gbps, a figure so astronomically removed from otter swimming velocity that direct comparison borders on the philosophically absurd. Converting swimming speed to data terms, the otter's 12 km/h equates to roughly 0.0000033 Gbps in metaphorical bandwidth, assuming a highly generous interpretation of what constitutes data transfer.
In practical household applications, WiFi speeds typically range from 50 to 500 Mbps, depending on router quality, distance from access point, and the number of teenagers simultaneously streaming video content in adjacent rooms. This enables the transmission of approximately 6.25 to 62.5 megabytes per second—sufficient to transfer an entire otter's worth of digital photographs in under three seconds.
The speed differential becomes even more pronounced when considering latency. WiFi can deliver a data packet across the globe in approximately 50 milliseconds. An otter, swimming at maximum velocity, would require approximately 3,340 hours to cover the same distance, and would face substantial difficulties with the terrestrial portions of the journey.
