Spiders can walk on water due to surface tension. Tarantulas can swim by rowing on the surface using their front legs.
The claim that tarantulas can swim by 'rowing' on the surface of the water using their legs is supported by multiple web sources, indicating that the behavior has been observed in some tarantula species. The use of their first three pairs of legs as paddles is also corroborated by similar web evidence. However, sources are mainly of medium reliability like personal blogs and forums, thus reducing confidence. The behavior is reported but not uniformly documented across all scientific resources, which is common for specific species behaviors that might not have widespread attention. The claim about spiders walking on water due to surface tension is a well-known fact in physics.

Science
Spiders can walk on water because of surface tension.
This is a widely accepted fact explained by the principles of surface tension in physics, requiring no further verification from external sources.

Tarantulas effectively swim by ‘rowing’ on the surface of the water.
The claim is supported by medium-reliability web sources that describe tarantulas using their legs to ‘row’ on the water surface. Sources include tarantula-centric websites and forums, which, while not the highest in reliability, provide observational evidence of this behavior, particularly in the Hysterocrates gigas species.

Tarantulas use their first three pairs of legs like paddles.
This specific behavior of tarantulas using their front legs like paddles is mentioned in medium-reliability sources similar to the accompanying swimming claim. This further supports the behavior without expert confirmation or rigorous scientific study.
