We sample their nests at low tide throughout the breeding season where we can easily collect tissues, embryos and nest characteristics from many fish across our different beaches and populations. [3] The other common name, "Midshipman" is based on the pattern of button-like luminous spots (photophores) which resemble the buttons on the uniforms of young naval officers known as Midshipmen. The herbivores which feed on plants are primary consumers and animals which feeds on herbivores are secondary consumer.
