Adult seahorses eat 30 to 50 times a day if food is available; due to their slow consumption they must feed constantly to survive. [20] Big-belly seahorses do not have a stomach or teeth, so they feed by sucking small invertebrates in through their bony tubular snouts with a flick of their head. Their snouts can expand if the prey is larger ...
Seahorses range in size from 1.5 to 35 cm (0.6 to 13.8 in). [13] They are named for their equine appearance, with bent necks and long snouted heads and a distinctive trunk and tail. Although they are bony fish, they do not have scales, but rather thin skin stretched over a series of bony plates, which are arranged in rings throughout their bodies.
Short snouted seahorses are considered ovoviviparous meaning that the female deposits eggs into a pouch on the males stomach, called a brood pouch, and the male goes through pregnancy and labour. [9] Sexual maturation occurs during the first reproductive season after birth.
The histological structure of their intestine is similar to that of seahorse species that also lack a stomach (agastric teleosts) such as the H. abdomnialis and the H. guttulatus. Thus, these species may have split from each other from a common ancestor, but more than just morphological data would be needed to confirm this observation. [11]
The seahorse is able to bend its tail ventrally due to its possession of body plates. The hypoxia muscle is responsible for bending the seahorse's tail. The plates send forces to the hypoxia muscles to ensure bending of the tail. These functions of the musculoskeletal system allow us to understand the anatomy of seahorses in further depth.
The lined seahorse (Hippocampus erectus), northern seahorse or spotted seahorse, is a species of fish that belongs to the family Syngnathidae. [ 3 ] [ 4 ] H. erectus is a diurnal species with an approximate length of 15 cm (5.9 inches) and lifespan of one to four years.
This damage disrupts stomach muscle functions by interfering with normal nerve-to-stomach communication pathways. 2. Post-surgical complications: Surgeries involving the stomach or intestines can ...
Hippocampus angustus, commonly known as the narrow-bellied seahorse, western Australian seahorse, or western spiny seahorse, [3] is a species of marine fish of the family Syngnathidae. It is found in waters off of Australia, from Perth to Hervey Bay , and the southern portion of Papua New Guinea in the Torres Strait .
