摘要: Dolphin behavior has been observed in both captive and wild settings for years. Comparisons of aquatic mammals have proven difficult because limitations placed on observers arenas; still research conducted each setting provides details often unavailable from the other environment. For example, internal body states (e.g., hormone levels) that might effect expression certain behaviors cannot readily be measured dolphins; however, they can routinely documented during husbandry behaviors. Conversely, detailed documentation dolphin travel patterns is more available long-term studies while are not applicable study individuals, observation movement within a pool examined to provide insight into an individual’s or inter-individual interactions. Long-term observations three dolphins populations presented comparatively illustrate how work groups complement one another. Additionally, data survey trainers (50 surveys distributed with 17 completed received) suggests interpreted several ways were consistent dolphins. tail slapping was reported mainly as irritation(45.5%) frustration (22.7%), but also suggested occur play (31.8%). Pectoral fin rubs used appeasement (15.4%), comfort (7.7%), affection (26.9%) so than sexual(7.7%) contexts at all (7.7%). Jaw claps, hitting, biting, chasing ramming aggressive captivity wild. More significantly, there no differences between by surveyed trainers. The author’s ongoing program merges advantages environments facilitate thorough understanding communication society.
