sentence grammars and anomalous grammars as well, demonstrating that the dolphins' comprehension was not limited to a finite-state (slot-based) syntax. The dolphins in this research were named Akeakamai, and Phoenix. Echolocation Pack and Herman (1995) demonstrated the bottlenosed dolphin's ability to recognize the shapes of novel objects across the senses of echolocation and vision. In other words, if the dolphin viewed an unfamiliar object visually, it could recognize that same object and pick it out amongst dissimilar alternatives when presented to the echoic sense only through the use of an "anechoic chamber", a box submerged underwater with a window of black acrylic glass that is opaque to light, but transparent to echolocation. The objects used for generalization trials were controlled for overall size (and therefore echo strength) and composition (all objects were constructed of PVC). These abilities were measured to be equally strong in both directions, echoic-to-visual, and visual-to-echoic. The dolphin used in this research was named Elele. Humpback whale In 1975, Herman pioneered the scientific study of the annual winter migration of humpback whales into Hawaiian waters, focusing on distribution, abundance, behavior, social organization, song, and individual life histories. He coined the term "escort" to designate male whale(s) trailing a mother-calf pair in the wintering waters. He was one of the first researchers to collect a photographic catalog of individually identifying tail flukes in the Pacific Ocean. In 1985, an errant humpback whale, dubbed "Humphrey" by national television media, swam up the Sacramento River in California from San Francisco Bay. Herman's idea was to lure it out by playing acoustic recordings of vocalizations from the whales' summer feeding grounds in Alaska. Cognition and communication Herman has also published on the following topics in animal cognition and dolphin intelligence: acoustic mimicry, behavioral mimicry (inter- and intra-specific), memory, monitoring of self behaviors (including reporting on these, as well as avoiding or repeating them), reporting on the presence and absence of objects, object categorization, discrimination and matching (identity matching to sample, delayed matching to sample, arbitrary matching to sample, synchronous creative behaviors between two animals, and comprehension of symbols for various body parts, and the comprehension of the pointing gesture and gaze (as made by dolphins or humans). Vision Conventional wisdom in the 1970s once dictated that dolphins were acoustic specialists, and that visual perception was relatively poor. Herman et al. (1975) hypothesized that the double-slit pupil shape enabled useful focusing in
