It was a member of a group of macroraptorial sperm whales (or "raptorial sperm whales") and was probably an apex predator, preying on whales, seals and so forth. Characteristically of raptorial sperm whales, Livyatan had functional, enamel -coated teeth on the upper and lower jaws, as well as several features suitable for hunting large prey.
The killer whales employed a tail outward and tail-slapping defensive position against the bull sperm whale similar to that used by female sperm whales against attacking killer whales. [205] However, at some potential feeding sites, the killer whales may prevail over sperm whales even when outnumbered by the sperm whales.
Should the schizomid not retreat, it will lunge forward and seize its victim with its palps. [15] The prey is then subdued, and possibly taken to the shelter of a nearby crevice to be eaten. [15] The chelicerae dismember the prey item before the tissues are liquified into chyme and ingested via suction with the mouth. [15]
Researchers examining southern right whales found that the median life span for the species was 73.4 years, and that 10 percent of individuals survived past 131.8 years.
The lumbar vertebrae were elongated and may have supported large multifidus and longissimus muscles in the back, likely larger than the modern sperm whale, and so it probably swam faster than the modern sperm whale; [1] the modern sperm whale typically travels horizontally at 4 kilometers per hour (2.5 mph), comparable to other large open-ocean ...
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
With the help of artificial intelligence, the research team from the Massachusetts Institute of Technology (MIT) analyzed data from 8,719 sperm whale “codas” —clusters of clicks ...
Draculoides bramstokeri is a small, troglobite, Australian arachnid.Often mistaken for a spider, D. bramstokeri is a schizomid — a small, soil-dwelling invertebrate that walks on six legs and uses two modified front legs as feelers.
