Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Pelagic species found in tropical and temperate waters worldwide, often migrating between surface waters and deeper zones.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

A highly migratory, pelagic filter-feeder that utilizes both vertical and horizontal habitat migration.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Forms large aggregations in specific offshore areas for feeding or mating.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Pelagic filter feeder.

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Feeds on zooplankton, specifically copepods, and small schooling fish.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Aplacental viviparous; females give birth to a single pup after a long gestation period.

Lifespan EstimatedExpected duration of life from birth to natural death under wild conditions.
Males15 - 20 Years
Females15 - 20 Years

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.

Males Multi-lang

Males possess external claspers; otherwise, sexual dimorphism is minimal.

Females Multi-lang

Females reach similar or slightly larger sizes and lack claspers.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Possesses a specialized heat-exchange system (rete mirabile) that allows it to dive into cold, deep waters while keeping its brain and eyes warm.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Highly susceptible to overfishing, particularly as bycatch in industrial purse-seine and longline fisheries.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

Known for its ability to perform spectacular deep-diving excursions, descending to depths of nearly 2,000 meters.
